Do you allready have the 1227730 computer? If not, there are several Chev Cavaliers at the local Pull-A-Part. It is the same computer, you will need the chip for the Camaro. I don't know if my son still has the Z28 tpi program. He used to do a lot of chips for the TPI. He did the one in my Cutlass that has a 383 w/ tpi. The chip is an eraseable programmable chip, so 15 minutes in a uv light will erase it. We did have an eraser, but he and I have both moved a couple of times since we used it so I am not sure where it is. He also had the harness and software to program the chips too.
