Where to start LM7 Swap So I have been building a 67 Camaro for a few months now and yesterday I picked up a 5.3L LM7. I just honestly don't know where to start. I read that I can use an intake, cam, and heads off of an LS1 and I would like to do that but I really need help with the wiring first. The engine has what looks like most of the harness but there are things cut off of it. It still has the fuse box and what I think is the ecu. I'm 16 so I don't really know much about the electronics. Can I use the current harness with ls1 intake, cam, and heads? I would like to get the engine started but I'm reading that the ecu needs to be reflashed with a new ignition barrell (correct term?) If anyone has been here I could really use some guidance. Anything helps
