Talked to the guys at on3 today, kit will not work with the 351 unless I lighten the cross over plumbing. Don't want to n*****rig it so I'm gonna stick to the 302

Ya I found a roller block for $100.. cheaper and less of a headache

Revhead I e-mailed on3 performance to see if the kit would work with a 351. If not I think the easiest rout would be to just buy a stock bore 302. Found some one craigslist for $50-$200.

Good point

No they do not. But I don't think there would be much difference other than it being taller. So maybe just add on another peace of plumbing to reach the top hat?

I just found a 351w roller bare block fir $100. Simple to convert mine or just take a drive and $100 for the roller block

What all do I need to make it a roller. Would everything from my 302 work? Sorry only thing iv ever messed with is 302s and mopars

have a non roller 351w. was wondering what all id have to do to make it a roller. i have a tfs1 cam, roller rockers rods ect all new out of my 302. dont know what will fit and what wont, or anythibg extra i will need. its going in a sn95. with an on3 turbo kit

That's kinda what u was leanin towards. I planned on just goin with stock internals gettin rid of my 13.1cr pistons and shooting for 8.1 and leaving everything else alone. And while I play with that be building my 351 on the side so when the 302 fries I'll have something fully built ready to rock

True. The tranny, diff, and suspension is still stock. should b ok as long as I run street tires. As far as boost I'll probably be around 10psi - 12psi. But we all know how that goes, first time u get beat u start turnin everything up. And I have been doing as much research as possible on the...

Just buying the sn95 kit. its for efi but it won't take much to make it work. I'm lookin for low 11s to mid high 10s. iv seen dyno vids of the on3 on stock 302s with cam only around 420hp to 500hp. As far as the 351 would I be able to use my roller rockers and everything. I think the deck hight...

My car is carb. Just getting a blow through. And as far as the heads I have gt40s with a lot of port and polishing work.

any certain years stronger than others? I can't find a Mexican block anywhere. But worried about gettin another stick 302 and crackin it

Thanks for the quick response. The problem with the 302 it was already bored .030 over. The shop checked it and almost every cylinder was a different size. And it only had 6000 miles in the last build. So either the last machine shop that did it messed it up or There was a problem internally...

First off I'm new to the site as of 5min ago. I have a 95gt. I believe it's and 86 or 87 block. I stripped everything last week. Took it to machine shop it has to be bored .060 over. First question .060 over, wouldn't that be alittle risky with that thin of cylinders being around 500+ hp and...
