What is all required to put a V8 into a '94 that has a V6 in it now? Is the computer and wiring all the same? Suspension? Exhaust? A friend of my son wants me to look for a V8 for him but I thought I would ask first what it all would take to do the swap. Any special motors to look for from a junk yard?

Ted - the practical advice is sell the V6 car and put the money toward a V8 car, you'll be money ahead this way. An LT1 out of a '93 - '97 Camaro would be the easiest retrofit but you need everything from cooling system, engine, trans and computer to get started. My understanding is the engine cradle (like a sub-frame) is different from the 6cyl to the 8. It's not going to be like yanking the inline 6 out of a 1st gen, changing the mounts and dropping in a small block...

By the time you finish funding this swap you could have sold the '94 and bought a decent '98 Z28 with an LS1 and made the 1st installment on insurance...

I 2nd buying a complete V8 4th gen VS replacing a 6 with an 8. I've had 3 4th gens (96 Z28 Vert and 98 and 2002 Z28) and even changing between the LT1 and LS1 isn't worth the cost.

done it. i got a z hit in the rear and swaped it over, alot of work had to swap everything but not that hard took about two 8 hour days with lift, nothing is the same you need a whole parts car . cheaper to just buy one that has a 8 in it but this v6 body had 60 grand in custom body and airbags and all that crap on it for the guy to start over

Not all necessarily true. I have a 94 Camaro that came with the 3.4 SFI and i put a 350 LT1 in it and the only thing i had to change was the gauge cluster and relocate the motor mounts and put struts from a z28 in. granted normally wiring would've been needed to but my lt1 came with the wiring harness. All works fine.
