This may be a dumb question, but I was wondering, if I bought a complete crate engine, and had the intake and TBI, what else would I need to get to make the car run?? Wiring harness, chip, what else? Can I reuse my a/c etc. from my L03? Hope someone can give me a list, thanks, appreciate much!

 

You should be able to keep all of your brackets and keep the ac. Might need larger injectors, different knock sensor. Just swap everything you can from the LO3 to the new motor. Get a motor with a one-piece rear main if possible so you dont have to get a new flywheel or flexplate. If you already have the LO3 in the car I dont think you would need a new wiring harness.
