What have you done to your 351M/400

[LEB Ben]

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.

 

[UNRULEE]

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.

Even though you don't want gpacks, I'll still recommend Cherry Bomb...their Extreme muffler is pretty nice. I've also heard good things about Aeromax mufflers (I think is the name), but they're kinda pricey.

Dynomax race bullets....

Those mufflers?

 

[JBradley500]

yeah but they dont really muffle any sound... ive got the 6" dynomax round race mufflers for my pick up but not installed. when i get the exhaust done ill make a video clip

 

[TexasNomad]

I still like how flowmasters sound better, to each his own.

Those don't look to bad actually. They're not really what I'd consider a glasspack, more turbo style than glasspack.

They sounds awesome

I've never heard any of those other Cherry bombs.

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]

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.

 

[LEB Ben]

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]

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.

 

[JBradley500]

i was reading me jegs mag at work and i see they have heat repelling gaskets too for 15 bucks.

 

[LEB Ben]

Geez man...you just keep making my list longer and longer, you should be making a commission on this or something...haha.
