305 TBI to 350 TPI

Currently I have a 89 firebird formula with a 305 TBI. I'm wanting to do a 350 TPI with maybe a turbo, but don't know exactly how. Right now I have a TPI Plenum, Wiring Harness, runners, Intake manifold and a fuel rail. Also, I have 58cc corvette aluminum heads that I want to be sticking on the 350. I'm looking at getting a 89 corvette 350 block to go with it. I want to make the 350 put out around 425 hp and 425 torque and use maybe a T-4 turbo to pick up on the top end. This is the first 350 I'm going to be working on, I usually work on 283s, 305s, 396s, and 454s, but never a 350, so I don't really know the weaknesses and strengths of a 350, if someone could clue me in on those, that would be great. Thank you.

Re: 305 TBI to 350 TPI

First of all, your doing the same thing im doing.. post is in teh engine swap forum.

I want to get my L98 TPI into my 89 RS LB9 TBI car, im just missing a few things that you have.. So maybe we can work on this together! (it will be my first 'fuel injected' swap.

P.s. I cant believe you have never worked on a 350? I dont think i would work on any other!
