Can you put a 350 Chevy engean in plase of 3.4 Chevy engean in a 1994 Chevy Camaro?

if you mean 4.3 then the answer is yes but you will have to change the brain (computer) to one out of a camaro that had a 350 alreadyand you will have to change the frame mounts and the wireing harness will still work but you will have to extend the alternator wire.hope that helps.

You would be Putting Alot of power in that Chevy my father had a Chevy suberban custom 350 in it and wow that big rig moved fast!
