i am converting my 94 camaro from a 3.4L to a 5.7L. i was wondering wat all i would need to change or modify to do this? i have a flowmaster cat back exhaust on my car now would i have to change that too or would it be alright? i was also wondering wat is the difference between the LS1 and the LT1 engines?

 

you'll need the motor, wiring harness for it, engine bay wiring harness, computer, radiator, bellhousing, transmission, K memeber, tranny k member, driveshaft, rear end advisable, but not a must have. Fuel pump, fuel lines, shocks and springs, I believe that is almost everything, did it a few years back and my head is foggy on everything.

don't forget the 3-4 12+hr days to swap it all

 

Its better to change the whole exhaust to a 3" system. And as far as changing the engine, check up a couple posts at the top. I think all your questions will be answered and gl!!
