So looking up the pickup coils for TPI V8's, apparently there are two different ones.
There is a LX324, listed for a camaro, and a LX320 for the corvette. (both standard motor products part numbers)
They both look identical other than the color of the connector. The camaro is yellow while the corvette is black.
The part numbers for the distributors are also different, but they look the same.
Any idea what the difference could be?
The yellow camaro connector fits lots of chevy and gmc, while the black corvette connector fits lots of buick olds, and pontiac

I am pretty sure I am using the yellow connector pickup coil (camaro). I will have to pull the cap back off and double check.
