Ok, so i have a 91 RS with a TBI 305. An if you read my other post you will see that i had a horibale experince racing a blazer last night. Anyways I've always liked how the intake manifolds look on the LT1's and seein on how it's a 350 an all i know ill get some power gain with further potential than a 305. so i was wondering if ya'll knew what it would actually take to drop this in my car. right now it's a auto matic but thinking bout converting it during the swap. also keep in mine i have acess to a shop with a host, crain, tool, and machine shop, an most parts at cost, so what would it take to do that. also i have a 350 on the floor so i would use that block with LT1 heads and manifold.

 

See if You can find a donor car ( wrecked ) and get the whole package ( engine, trans , computer, fuel system. etc. ) and swap everything out. It'd be cheaper to buy a wrecked car and take it out, a wrecking yard would kill Your wallet.

 

The LT1 heads and manifold won't work on a regular 350, water passage problems. You also need the LT1 block. It would easier to put a good set of heads, cam, and manifold on the 350, or get a donor car as uncle bill stated.

 

I have the exact same car as the guy originally positng here. I have no ability to do the work myself, but I am wondering, if I was to purchase the doner car or the parts, what would it cost me to have the engine-tranny combo swapped? Would it make a difference between LS1 or LT1? I used to have a 96 WS6 Trans Am which was fast enough but my TBI 305 just never cut it. It was my first car and has been sitting for 5+ years now. Still looks good but it needs some major mechanical work. Thanks for the help.

 

I would personally go with the LS1...thats what I am thinking for my 2.8 swap but its that or a 350. I know there is a lot you can do to an LS1. I know someone who owns a trans am LS1 with a rear mounted turbo that thing flies....600HP at the rear wheels

 

LS1 was built for power and abuse. It is a 6 bolt main!

So any idea on the cost of install?

 

IMO you should take the 350 you have on the floor, with a good set of heads, cam and manifolds it cam make as much power as the LT1 or LS1, and save yourself a lot of work and money. Small blocks used in NASCAR racing produce 700 to 800 HP with a 4 bbl carb, so the potential is there.

 

well what im doin now is this. I have a 350 out of a 93 chevy 2500. i pulled the head and i'm havin the milled .20 then im changin all the gaskets an seal an maybe changin the came..dont know for sure. boltin it all back up an putin her back in.
