1967 Camaro Ignition Coils

Thanks very much for the tip. I had thought about the AMA data and I believe I have a copy of the file somewhere as I'm pretty sure I downloaded it sometime in the past. I was going to check it but never got around to it. The AMA data was issued on 10-7-66 which is the same date as the harness number was changed in the AIM. Possibly a coincidence. Looks like the 039 coil on my car is original equipment and meets the date criteria. I'll measure the resistance of the ignition to coil wire tomorrow. Today I measured another 1967 Camaro harness I have and it measured 1.8 ohms exactly as per the early specifications. I also measured a 1968 Nova and a 1967 Firebird 400 that I have and both were 1.5 ohms. Not sure what the spec is for Firebird but the 1968 Nova spec is 1.35 ohms.

I went and checked out the Camaro today to measure the ignition to coil wire for resistance but it was really too difficult to do quickly now that it is pretty much finally assembled with all the sheet metal and wiring in place. I'll have to do it another time. I now know that the wiring harness and the coil were all born together so I'm not worried about an incompatibility problems.

For those who are interested I've attached the AMA spec.
