I have an "MSD style" GM Performance parts small cap distributor you could team up with a hidden GM hei module. I also have the GMPP box and coil that goes with it. it looks like a points distributor but no vacuum advance.
I used to have a small aluminum finned heatsink with a HEI module on it that we had on an old car with a ford pick conversion points distributor and it worked fine, gotta dif it up though. email me at
