I have a 1985 monte carlo with a 4.3L V6 engine and I want to swap it with a 350 from an 88 Caprice. Any advice?? Suggestions, etc???

should bolt right in, motor mounts might be different but if they are there will be little to no difference. the exhaust your running now should bolt right up also. we put a 350 in a astro mini van, and to our suprise the down pipe that was used with the 4.3 bolted right up to the 350. i figured we would atleast have to move it a bit

more than likely you will have to get different motor mounts. That's what I had to do to my g-body.

change your radiator too.

 

[REALTALK]

yeah what he said. Change the radiator.

and the fan shroud?

 

[REALTALK]

gotta do that also. also gotta get a new fan. Unless your gonna run an electrical fan. Just a suggestion.

the chevy 4.3 is basicly a 350 or 305 with the two front cylinder off that 350 should bolt right in like a glove all the front parts like the power steering pump and all the alt. brackets should bolt up to

In every g body 350 swap topic everybody says to watch out for fan shroud, radiator, motor mounts, etc. BUT, what about the issues with EFI and computer issues? Does anybody have input on this?

 

[warning]

are you using efi? if so then keep the computer from the 350 donor and get awiring harness from painless wiring...........its all so simple......
in theory

I got more money than patience, so I'm debating on whether or not I should attempt this swap by myself or take it somewhere. I know I should probably try it myself, but I don't know.

And I do have an 85 MC SC, 4.3 EFI.

 

[warning]

if you got the money then let some one else have it........
