Looking up the parts on rockauto, a 1985 camaro with the 305 tpi V8, and a 1985 corvette with a 350 tpi V8, they both show a large cap HEI distributor and they both look identical, but have different part numbers.

The pickup coils look identical but have different part numbers.

The coils (both large cap hei coils) look identical, but have different part numbers. The corvette has a red and yellow wire, while the camaro has a red and white.

The 7 pin module is the same part number.


Ok, doing a little more digging, I found reference to different ignition coils and that they need to be matched to the pickup coil. He says the coils function the same, but the polarity is reversed on the two, so the pickup and coil have to match.

I think I am just going to have to pick one (either camaro or corvette) and order both the pickup and the ignition coil, just so I know they are both matched, as right now it is a mix of junkyard parts.
The pickup I pulled out had the yellow connector and I am pretty sure the distributor came from a camaro. So I think I am going to pick that.
And yes, I do have the ground strap in place. I specifically remember putting it back in there.
