I've recently purchased an 81 CHevy C10 aswell as an 02 Vortec 6.0L V8, complete with ECM wiring harness and 4L80E. I'm getting complicting stories on how this must work. I've been told that aslong as there is no BCM (Body Control Module) I wont have to have that portion of the ECM reprogrammed. Also I have been told that I must purchase a new wiring harness. I have the wiring harness on the 6.0 all hooked up and ready to go. I have the stock wiring harness in the 81 ready to go. Will I somehow beable to splice into the stock wiring harness from the ECM of the new engine and make it control only the engine and tranny?

Motor mounts, I have the mounting plates that attach the engine mounts to the frame, what kind of adjustments am I looking at here?


Any input will be greatly appreciated!
