gutless 400

[Bleever]

So, my 79 is super reliable, but no B*lls!

should I rip out all the smog junk, thro in Edelbrock 2171pk carb/intake/cam/lifters Voila! 300 HP. Opinions?

F250 with service body, 4x4 4spd man. work truck. used for towing. budget under $1000. thanks. BL

Before you do any of that, do a compression test and make sure the cylinders are good, cuz it would be pointless throwing money into a trashed engine. If that checks out, Do it. Although, I think that 300 is bit optimistic, I'd probably say more around 250 at the engine. Go with the Eddy intake, a carb no bigger than 650 cfm and these engines seem to like the 255DEH and XE262 cam kits from Comp.

Can buy a Weiand Stealth intake for cheaper but if yours comes in a kit then you're probably better off with the Edelbrock

Weiand Stealth isn't made for a 351m400. There are two current bolt on choices, the Edelbrock Performer or the plain Weiand.

I did a 265Deh CompCams valvetrain (bumpstick, lifters, pushrods, straight up timing set, valve springs and keepers), Edelbrock Performer intake, and a Holley 670 T/A carb. It turned my 400 into a completely different animal.

I think the compression test is first on the to-do-list...thanks

you forgot to add a couple hundred for pistons

also forgot to add the valve springs... although if it were me i would buy the cam lifter valve spring and timing chain kit. so you aernt just mix matching parts. and a lot of times the valve springs are going to be pretty close to the best combo for the cam and lifter kit. this being said cam and lifter kit should be revised to about 350 to 400 if he runs comp cams

To the 77 400 in my 'scapers F-250 converted to dually we added Weiand intake, Holley carb, Summit 14x3 air filter, Summit air cleaner tri bar nut, Summit headers, cam/lifter kit, timing chain set, Fel pro gaskets and Edelbrock chrome valve covers for about $915 from Summit Racing to the shop door. Got rid of the emissions crap, reassembled and he had the biggest smile as he smoked all 4 rear tires leaving the shop. If your long block is good with compression and oil psi that's less than a grand, take out the chrome and save $75 bucks and $850 will wake her up. I don't know what the exhaust starting at the headers will cost by you, He got away with 18' of 2 1/2 pipe, 6 clamps, 2 Cherry Bomb Turbo muffs and 2 turndowns, ends just before the back axle cost around $100 or a bit less, which may put you over budget but not by much.
