Alright now...gonna try to liven up this section a little bit. I'm just wondering what you guys have done or plan to do to your 351M/400. I realize most folks regard these engines as boat anchors and swap to a 460, but I love them with a passion. I'm also looking for ideas for the engine build in my Bronco.

Here are the specs on Red's 400:

Holley 4150 650 cfm electric choke vac secondaries
Eddy Performer Intake
.030 overbore and hypertuetic step dish pistons
XE262 Comp Cam
Sanderson FC3 Headers
True Duals...2.25" pipe through 12" Cherry Bombs

Dyno numbers= 347hp/442tq

Future plans call for a Barnett 496 stroker, CHI 3v heads, Holley 4150 850cfm, offenhauser intake...that would be 550+hp/600+tq on premium fuel


Here are the probable specs on the Bronco's 351M build to be done by Easter:

Holley 4150 650cfm
Eddy Performer intake
.040 overbore and TMI pistons
XE256 Comp Cam
Hooker Headers
TMI 400 crank
True Duals...2.5" pipe through 8" Cherry Bombs

Desktop Dyno=342hp/440tq


So please guys, share what you've done or plan to do, and even give me some suggestions.

I'm going to be upgrading to a 351 soon I hope but I want to stroke it out to a 383, I don't understand why so many people don't like the 351/400 engines I think they are great engine and the people who have had them really love them.

Yanked mine out of a Lincoln Contenental that had been sitting in the wooods for 8 years.

After a tune up, oil change and fresh gas, it got transplanted into my flatbed car hauler.

The car hauler was used for a few years then went to the scrapper. The 400 was once again transplanted, this time in my 66 Scout. It even got headers. :D

Hey Tony...always good to recycle a 400...I love the headers on the corn binder. I've always had a soft spot for IH's...my dad used to have '78 1 ton sitting on 38's when I was a kid...it was a dark purple metallic and it was named the Executioner, he used to show it up in Wisconsin. When he sold it, the guy owner let it rust away.

Another reason I can appreciate a recycled 400 is because I have a 400/C6/205 combo in my 73 Waggy that I let my girlfriend 'wheel. I just feel you can't kill that combo.

Once again Tony....I hate you so much right..
You know i've been thinking about getting a stroker but would a 400 be more then enough engine for a good street truck, i'm looking for the best low end torq with out getting in to larger big blocks..

01-08-2009, 08:04 PM
A 400 has plenty of low end grunt. Just replace the retarded stock smog timing set with a new one, set straight up.

When work picks up again this spring, I will be putting a 400M in my '77 F-250 4x4, to replace the current 351M that has 300,000 miles and a broken connecting rod.
The 400 will be getting an Edelbrock 4 barrel intake, a set of Flow Tech ceramic coated headers, and a 670 cfm Holley Street Avenger carb.

The old 351M will be getting a 400 crank, a cam that provides better torque, have the heads rebuilt, ported, polished, and shaved, (just a hair) new forged rods and pistons, bored .030 over, Edelbrock 4 barrel intake, 770 cfm Holley Truck Avenger carb, new timing set, and Flow Tech ceramic coated headers.
Not sure what I'm going to put it in yet.
Thinking about putting it in my '77 parts truck, if it doesn't sell by then, and making it a trail rig.

C'mon fellas, I know there are more guys out there with an M series. Even if all you want to do is get better oil pressure or stop blow by, post what you want your engine to be like.

I feel like the 335 series is commonly overlooked and misunderstood, and we need to get this section going and show the 335 series the love it deserves.

I'm with you there!
My first vehicle was a '79 Bronco w/ a 351M, and I loved it!
A buddy of mine in upstate New York bought it from me, and drove it until the body was so rusty, that it started falling off of the frame.

He then transplanted the engine into a '79 F-250 4x4 Ranger that he was restoring, and unbelievably, it is still running with over 500,000 miles on it!

He says that he is going to rebuild it this spring though, as it is getting weak and using 2 quarts of oil a month.

Never had a 335 series motor, had friends with them, but never owned one, didn't really see problems with them, its just for the money you could put into them to make power you could put the same into a 460 and make more power...
So that makes since... I dont hate the 335"s by any means.... Not sure what everybody has against them.

Yeah yeah...sure sure, bring that blasphemous talk to the 385 series section...haha. I 100% agree with you though, no replacement for displacement. So I guess the reason I feel so strongly for the 335 series is because I had one in my first truck...Red. And when I gain a connection with a vehicle, I try and keep as much original as possible...now when it comes to engines that to me means, basically just keeping the original block. Another contributing factor for me loving the 335 series is probably out of mere necessity, it's soooooooo hard to find a good donor 460. Now believe you me, if I had a good 460 lying around and a vehicle where I didn't care about originality, the 460 would go in hands down. But the fact of the matter is, in my area, usually the 460's need too much work to get them right, and then build them.

I love the 400. I've had a 460 and it is awesome, but if 385's weren't available we'd all be raving about the size of the 400 - I mean come on, 400 cubes is a bunch. Besides, torque is cool!

I probably posted this before, but I have a 77 F150 2x in the pasture waiting for a transplant. The 351M/C6 is worn out.

In the shop waiting for me is a 400. On the shelf is a collection of parts including: .020 Badger pistons, 268 Comp cam (IIRC) and new lifters/springs, new timing set, Weiand dual plane intake and a 650 Street Avenger carb.

I got distracted by flatheads a few years back and so the mighty 400 sits patiently waiting. Plus my shop is usable for only 3 seasons (unheated) so repairs and rebuild depend on the calendar.

No worries man...some of their bigger stroker engines aren't really great street applications obviously and I've been told by a few guys that some of the Barnett engines are pushing the structural integrity of the block and don't last much more than 50-60,000 miles. However, if you can tone down the ego, and get a better street application, not too many problems that I've heard of.

I agree, the bernett engines are just for TOWING aplication, other than that why go higher than a 434 small block? anyways they warn people to use barnetts strokers softly, why would anyone want that=? engines were made to be tough.............. hmmm wasnt that fords idea??? Oh yeah Hiii

How the heck do you use a engine softly whats the point of even having it!

hollenjoe
01-13-2009, 12:08 AM
exactly my point, he advertised his stroker a while back in fte, i asked about a 498 cid stroker he said something like they shouldnt be streesed, i dont remember exactly but thats the idea... anyways, what have i done to my 400? as the thread syas, I have 10:1 scr a costum made extreme enrgy xe269h comp cam, stock heads ported a bit on the exauhst side, large tube headers 750 eddy performer

Im pushing 400hp @5000 and 462lbs of torque @ 3500

I have the michigan bad year block (`73) (still waiting for it to crack jejej) in my 73 mach 1, and i love it, good fuel economy even for a 6.7lt engine and amazing pulling power even with my 2.75 gears...

01-13-2009, 12:40 AM
10 to 1! wow are you running Race gas?

hollenjoe
01-13-2009, 01:49 AM
93 octane, thats the reason i designed the camshaft, it lowersmy dynamic compresion down to 8:1 perfect for 91-93 octane, its even lower than having 9.5:1 and using one of the rv cams most people use, like the xe252h or even the xe262h. oh and these cams have a 4 degree advance set on them so their ICA is set by default on 106 giving you a higher dcr , my xe269h has it straight up(110) lowering even more my dcr. And the results are great mid range (streetable 400hp) and amazing torque comparable with those obtanied with an rv cam...

Remember, static compression ratio doesnt determine your octane needs, dynamic compresion does...

Is that how you work all your magic...using those two links? Looks like I'll still have to ask you for help though. I have no clue what some of the definitions are of those terms. On top of that, when I did try to input some info and calculate, it said:

Warning: divinding by zero is prohibited...and then gave me danlee's username.


Looks like you still got a job from me at least...haha.

hollenjoe
01-13-2009, 11:27 AM
those pages got me started, anyways, you have to set everything in order from top to bottom, calculating first rod ratio, static Cr etcc... after setting each item use the back on your browser and continue, use 170 operating degrees cuz these settings where calculated using old under the deck pistons...

Most engine builder dont know what dcr is and its the most important factor in engine design acording to its purpose and octane needs thus making the most efficient engine you can calculate on paper...

First off high to all, my first post here in the boards :wavey: !

I love my 400 in my 79 250. Yeah stock it was pretty doggy but I've added an Eddy intake, Holley 670 TA, Comp Cams 265 Deh K-kit (cam, lifters, t-chain set, valve springs), Heddman headers (Sandersons are in my basement rusting away) and a DUI/HEI Dizzy. It'll easily turn well over 5500 rpm now. Completely different truck.

Once it gets tired I plan on doing a teardown and putting some higher compression Tmeyer pistons in the holes on the rebuild.

UTfball68
01-13-2009, 07:52 PM
Hey man...glad to see you over here. If you got Sandersons rusting away...I think I may be able to put them to good use for a good price if you're not gonna use them...haha. How's the 400 like that 265 cam? It isn't too much is it?

UNRULEE
01-13-2009, 10:38 PM
Actually rusting away is a figure of speech, they better not rust since I spent the extra coin on the ceramic coating! I just need to find the time to take my terrible Heddmans off and put the Sandies on.

You stated that you have Sandersons on one of your trucks? What method did you use when you installed them? Did you use the optional copper adaptor (4v to 2v) that they also sell? Or just regular 2v gaskets?

No, the 265 isn't too much in my opinion. With my current tire size and gearing (35's and 3.54's) a 255 stick would put me in a better rpm range, though. But I tried to do this build up with the future in mind when I regear the truck to some thing like a 4.30 or 4.56. This cam really sings in the midrange and deeper gears would get it there faster. Don't get me wrong though she still has plenty of grunt down low.....just has more lung capacity now.

Allot of people talk highly of this Tmeyer guy, one question about the 351/400M do all the aftermarket parts for a 351c/w cross over to M model engines? I can find 351 400 M engines allot easyer then the C or W's?

I figured you were just being facetious about the headers. I do have Sanderson's on Red. I just went with the 2v gasket. As far as what method I used to put them on...I got them on before I knew too much about working on vehicles, and I had the shop that rebuilt the engine when I first got it do all the work.

As far as I know, NOTHING from the 351W is tranferrable to the 351M/400, although I've heard of guys using the SB starter on a 335 series, but have yet to actually see it. As far as the 351C is concerned, I really don't know how much can be used on the used on a 335 series. I know there are adapters for intakes, and the Sanderson FC3 headers are actually a 351C header, so those are interchangeable too. I don't believe you can swap too much of anything internally, but I could be wrong about that.

The 335 series market seems to have 2-3 producers of a certain part while the SB or 385 series has upwards of 10 producers. You just need to know where to look. Keep in mind, anything besides the crank is swappable between a 351M and 400.

Well the SB is obviously smaller, so I don't think it would physically fit, but I don't claim to know anything about SBF's. As for the the 351C intake, it can be adapted, I know it's been done, but the kit costs about 4-500.I don't know why the 351C doesn't fit, never had/looked at one.

01-14-2009, 05:43 PM
I know that if you swap the drive gears on distributers they'll swap.


As far as Cleveland swapping, correct me if I'm wrong but the cams will work, heads, water pump, timing set, valve covers, and 351c pistons will work in a 400 if you use a bushing to make up the differece in wrist pin diameters.

hollenjoe
01-14-2009, 09:20 PM
exactly like unrule said, between a W and a C(or m), olny some accesories would swap, besides that nothing else, although if it counts a 400 crank fits a 351w with some mods, it was a popular mod till forged steal cranks appeared of such stroke...And cleveland heads work on Windsors ith some mods and a boss or costume inatke..

400 with a C6 = different starter.

The 434 I am having built for that 1979 truck will have the 3V CHI heads, CHI manifold, 780 carb, roller rockers and cam, obviously the stroker crank and will do the 4 bolt main caps. Tim figures around 12:1 compression and I should be able to run that here on 91 oct. with the altitude and the AL heads being a closed chamber design.

I don't think I want a engine that I can't swap simple things like intakes, headers dizzy's off other engines I don't the have money to buy every thing new so I buy allot of used stuff off ebay or CL and its not easy to find used parts for M engines.
And on top of that every thing for the M engines is more expensive then the Windsor and Cleveland blocks I can't see the reasoning behind owning a engine that cost more and is harder to find mods then to just find a Windsor block..

The 434 I am having built for that 1979 truck will have the 3V CHI heads, CHI manifold, 780 carb, roller rockers and cam, obviously the stroker crank and will do the 4 bolt main caps. Tim figures around 12:1 compression and I should be able to run that here on 91 oct. with the altitude and the AL heads being a closed chamber design.

Holy hell, 12:1 and 91 octane. Hell even with my engine at 350hp/440 tq it's gonna have to run premium (but I'm only doing bare minimum upgrades, no heads, or valve work, etc). I always loved Tim's 434 and will have one eventurally. If you don't mind me asking, how much is your total build gonna cost?

I don't think I want a engine that I can't swap simple things like intakes, headers dizzy's off other engines I don't the have money to buy every thing new so I buy allot of used stuff off ebay or CL and its not easy to find used parts for M engines.
And on top of that every thing for the M engines is more expensive then the Windsor and Cleveland blocks I can't see the reasoning behind owning a engine that cost more and is harder to find mods then to just find a Windsor block..

Well then buy a Chevy, I hear all they're junk swaps...As far as I know, Ford Small blocks are only swappable with eachother and some 6's, 335 series have some swappable stuff, 385 series are swappable within eachother. Given that's a loose statement. The stuff you listed, for a SB, you'd need another 302 or 351W, with the 335 series, you'd need a 351M or 400 (and sometimes a 351C) and with the 385 series, you'd need a 429 or 460 to be able to swap stuff. SO it's not like the 335 series isn't like every other Ford engine family. And there are plenty of places to find used parts too, type in 351M/400 in ebay, craigslist or google...lots of results. I guess I don't really see or understand why you think the 335 series is so hard to find parts for, or why you think the series is any different than anyother Ford engine family.

It should be around 6k US, that is with me getting some machining done here and a friend giving me a hand with the build as I really haven't put an engine together in 20 years. The altitude helps here, our bikes run almost 11:1 and they are air cooled...they can be made to ping if you lug them....the cam Tim is using (which I don't fully know the specs yet) will help as well.

hollenjoe
01-15-2009, 07:55 PM
thats hwere 335 series engines rock, theres a large selection of heads for the cleveland engines or 335 series (302c 351c 351m 400), even people with windsor use cleveland heads on their engines. The cheapest but great way to go are the aussie heads, you can get them with tim meyer..

TexasNomad
01-15-2009, 08:08 PM
I was reading about the aussie heads some place else.
They sounded really good.

Behemoth
01-18-2009, 02:49 PM
Yup, the aussies are a fairly good and economical way to go. Tim Meyer is a dealer in those heads, as well as those from Cylinder Head Innovations (CHI). If you're willing to blow a bit more cash, the CHI heads are a good way to go as well.

Myself, I'll be going with the CHI 2V heads when Tim does my longblock in the next month or so. I could go the same direction like Dan, and go with the 3V, but the CHI intake doesn't support Ford linkage nor does it have the mounting positions for the factory cruise either. I'm hoping to place my order with Tim in the next few weeks.

As for interchangability of parts, it's 6 in one, half dozen in the other. Every engine class has parts, some harder to find than others, but it still boils down to a matter of taste. I'm going with the 434 option, as the 400 was the largest V8 put into 79 4x4's, and I want to at least keep marginally to the spirit of originality. Besides, when you see 460's all the time, seeing something weird like a 400 that's been all done up is refreshing (my opinion).

On that subject, when I last spoke to Tim, I believe he said that there either was or they were working on a set of adapter plates to make a Windsor intake compatible with the 400. That would open up a couple doors for folks here, as the 351W has EFI options all over the place. I think a 400 with a 351W GT-40 EFI intake would be quite the sight (pity I sold my GT-40 351W last summer).

But then, if I was truly sick in the head, I'd use my 428CJ parts and drop that into Buford. Now THAT would be interesting....but way more work than is necessary.

Oh, by the way....I find it odd that this forum only has the 351m/400 in the title. Where the heck did the 351C go? It's in the same family, and it's not listed in the index. I think an administrator here might want to revamp in that area, especially considering all the Cleveland stuff that works on our engines. Just a thought.

Anyway...thought I'd blather a bit...especially since it's my first post here. I'm still torn about the idea of splitting the crowd from the other site, but I suppose those things happen.

Yeah, I'll never argue that old worn out 335 series have oil problems, or that there is no replacement for displacement. BUT...if you have the time and money to show them a little TLC, they're a great engine. I believe TMI showed that the 400 is about 150 lbs lighter than the 460.

.060 over...holy crap, how'd those cylinder walls hold up? I've always been told you don't wanna go with any more than .040 bore job. As far as the 4bbl Holley, it couldn't have been tuned properly or was too much carb for the engine. The 4bbl will always give more power and better mpg's. Dyno proven in my case...I use the Holley 4150 650 cfm on all my rigs, and I always gain 12-15 hp and 2-4 mpg's.

Yeah no kidding 60 over is way to much, the only times I ever hear about going that big is the cylinder being way out of round and then they have to sleeve it.
If your having a issue with PVs blowing out then you need to get the PV blow out protection kit, you'll never blow have to deal with blown out PVs again.

I will give the 335 props there. My tires hit the fenders occasionally now, they didn't with the 351m, my 460 has iron intake and exhaust manifolds 'smiliedoh' .

01-25-2009, 07:25 PM
Yeah...as far as I'm concerned it was the best of both worlds...it was like a big block mixed with a small block. It's lighter than the 460, and can still get the job done, and yet it's got more power than a small block and not too much heavier.

Yeah, I've heard that too. I knew .060 was about the limit you wanted to go on 335's, but then you have to start worrying about cylinder wall thickness. As far as the .125 on FE's...I have heard of that too, something like some folks were trying to turn there 390 into a 427 sideoiler or something. Anyways, I've talked to some experts, and they say that there's only a handful of blocks out there that can actually hold that .125 bore, the rest fail miserably.

My 428 that I blew up was .060 over and two cylinders cracked so Im thinkin maybe see if we can get er sleeved but its down the road. The 427s bore was 4.23 and a 390s is 4.05 but the 427 was a reinforced block with thickened up walls too. We were thinkin about borin out the 352 I have to match the 4.08 bore of my 390 which would be .080 over but thats another story for another day.

01-25-2009, 08:03 PM
Yeah I know Don, but this is just an extremely mild build and can't afford much else. I'm doing the exct same build in my Bronco as I did in Red, which is a Dyno'd 347hp/442tq at the rear wheels, and this is all for under $3000. So I'm pretty happy with that, right now I'd be happy if I could keep good oil pressure and stopped blowing oil all over the place in the Bronco. But after the Bronco comes a moderate to wild build on the 460 in Thunder, since I have the first engine on a stand. Then comes a moderate to wild build in Red, then the Bronco will be up to bat again.

It's on a stand right now, and I haven't even started researching on it yet. I was thinking a 557 stroker, but Don showed me some info and convinced me that a 521 would be the way to go.

Nothing wrong with Rochester...good carb. As for the whole Eddy vs Holley thing...I always run the 4150 650 cfm e-choke and vac 2ndaries, great street carb, good offroad carb and can be tuned well for power. One of the main reasons I prefer Holley is because they are wet tested resulting in a mor accurate cfm rating which allos for the 'more power' tuning. Eddy's are dry tested, thusly, the actual cfm's are much lower than the advertised cfm's.

A mild or wild build can be done with EFI, but you need to plan for more expenses...
Fuel pump, pressure regulator, injectors. New comp probably, and a good tuen....
With a good tuner you can get different power levels for different gas....
And by tuner i mean somebody to tune it for you, not a little hand held unit.

You can get mild tunes, to wild tunes....
Its all up to you.
Tuning is something i am starting to get into...

where would you recommend i do that?

I've found the easiest way to post pics here is through photobucket. Upload your pics there and then copy the IMG code, and paste it in your post.

Hey Wyazel...I gotta ask, where did you get those valve covers from? Most the time all I see are for 351W's. I can never seem to find a place that has 351M/400 VC's. And I gotta ask you, what made you decide to go with Hedman Headers?


I had always heard good things about the Headman and i was also concerned about being able to change a starter without header interference. So far I like them alot. I got my VC's thru summit. I didnt spring for the chrome but i am looking for a good cleaner to polish mine with.

it would be nice to make that kind of hp but i'm not really sure to be honest...i was going to guess right in that area but if i only see 425 or so id still be quite content.

UNRULEE...looks like a nice clean build, going from that stock power to built power is one of the best feelings in the world isn't it? My Bronco is so worn out it's probably only getting 90hp to the ground...yuck...I can't wait to finally get into the tear down/build up stage.

PS...I'm still veeeeeeeeeeeery willing to take those Sanderson's off your hands...with some compensation of course.

Yeah it's defintily something that I an very proud of. It's an amazing upgrade from the stock 400. Not bad for not even pulling the heads off or breaking into the bottom end. Shows just a hint of the easily tapped power in these engines.

Oh and on the Sanderson issue................HAHAHA!!! That's funny! Well my plan is to actually get them installed by summer. I just need to decide on mufflers??? I know that I want 2.5" pipe with a x-over, just not sure on the mufflers. No glasspacks though, been there for the last 15 years, want something that sounds throaty untill she really starts working. Flowmasters or Magnaflows probably. Tired of the "rappiness" that comes with the 'packs.

Anyone here use a carb spacer? Are they worth it or just hype? I don't know a whole lot about them except on design is supposed to help in the low end and another design is supposed to help top end. I also believe the taller the spacer the more it helps top end...so any info, please post.

JBradley500
02-09-2009, 11:36 AM
its all about what your engine will want so a dyno is the only real way to optimise a spacer for your engine. but a 4 hole phenolic is the best for a truck and 1" is a good size. thats what i went with, an edelbrock, and i think its worth the money just for keeping my carb from gettin hot.

35 bucks isn't too much money for the one i have but if you have 100 you should get a HVH super sucker.

UTfball68
02-09-2009, 11:46 AM
Thanks for the info man...I don't think another $100 would hurt too bad. Just looked at their site...and it says the super sucker could potentially add 47hp to a NA engine...sweet. I realize, with my setup it probably wouldn't be anything over 10hp. I do have a question though, they have a 1" spacer for the 4150/Performer combo, but it's only aluminum...aluminum transfers heat pretty well...should I steer clear of that, or don't you think it'll make that big of a difference?

JBradley500
02-09-2009, 11:57 AM
you can stack them... if you wanted to get a open .5" phenolic spacer to keep out the heat. i do worry about heat transfter.

Ding Ding Ding...we have a winner. They're not the biggest with the most power (see 460) and they're not the best high winding (see SB)...but daggon they can be made into a pretty sweet engine, and with so few guys wanting to build them...they add a unique factor.

I had my cel with pics of 400 psitons and 400 intakes, I debated the guy in front of alot of peolpe... Showed him my car, He was so embarassed ....

Ha! that;s funny, at first I was very misinformed about the 351M/400 engine but even I knew new more then him, uh, I think.
And i'm pretty sure a 460 is much heavier then a 400, I know a fully dressed 460 is in the 650 700lb area..

Yes Tex...the 460 is about 150#'s heavier. IIRC, TMI had/has some pics of some SB's, 335's and BB's on their site on the scale. I'm pretty sure the 460 came in at 725-750 and the 400 was 125-150 under that.

Cuz they're not the big boy on the block, and cuz they're not high winders. Bad factory specs play a role with that too. Figure you want the baddest gas engine...go 460, want a good towing rig...go diesel, want high revving and racing...go 351W. So there are better platforms to start with than the 351M/400. So most guys just start with the best they can get to begin with. Figure you put $3000 into a 400 and you put the same amount in a 460...the 460 will put better numbers out. A 400 isn't really designed to compete with a 351W...so why go that route? So they are misunderstood, but most people want the best possible platform for their application.

TexasNomad
02-14-2009, 10:04 PM

Your guy is wrong, its pure geometry man, i measured my heads ccs, pistons ccs and compared them to the full strokes volume and ended up with a 10:1 relation, anyways i think on the contrary, people are having more compression than what they think they have.

I'm not sure why I like the 400's, but I do.

Maybe it's because they're the only stock 4" stroke motor.


Ive never heard that before, is it the only ford motor with a 4" stroke or did chevy make one also? What is the stroke on a 460?

Quick! I need a way to add about 300hp to my 400 for next weekend. I have a budget of $65. :D

Yes it is. The 460 is a tad shorter.

The modular motors (5.4 v8 and 6.8 v10) actually have a longer stroke (4.15 I think), but before them the 335 series 400 had the longest production stroke of a Ford motor.

Ive got nothing done to this motor aint wasting any money on it neither not doing oil changes either. The modified is a waste of money i would rather save up and buy a 429 460 and blow up the m and use it as a boat anchor.

A 400 would not make a good boat anchor. They weigh, what about 500lbs? Try lifting it and throwing it off the bow of a boat. Try pulling it back in. Not good. :p

When I find a 460, I'll give you my 400. Only catch is, you have to pick it up. I don't deliver.

not that I dislike the 400, but in a mud truck, I prefer the extra cubes of the 460.

Dang...completely forgot about this Thread. Red's 400 has remained the same, but the Bronco's has drastically changed. The 351 was pulled out, was holding about 15psi at highway speeds...had almost ZERO compression in 2 cylinders and #6 had a busted piston skirt. So I pulled it out and threw in a 78 400 with roughly 90k on the clock. Threw that engine in right from the field. Drove it around for 6 months like that until every seal and gasket leaked. Then pulled it apart and did complete re-seal/gasket job to it. I threw a Comp double roller TC in, some Taylor 8mm wires, a Pertronix coil and called it good. Now it's looking like it's going to get a fresh distributor too.

Well, I haven't done much to my '90 except replace the whole damn thing. It came stock with the 5.8L option ticked, but I blew a head gasket last fall and did enough damage to it that I decided to just swap in a new motor.

So I bought a new ATK Stage 1 351 Windsor, rated by the manufacturer at 300HP/370lb-ft of torque. Haven't had it dyno'd yet, but I'll get there. I've also got a nice little K&N cylindrical-style intake, as well as a cheap-o Flowmaster Hushmaster exhaust. Single pipe, side tip. Makes a nice rumble at idle, but doesn't sound too much different from the stock system at highway speeds. Until you gun it, of course. ;)
