The HEI from any GM I-6 with a 4 wire connector will work. Started in 73 as an option on Olds, all cars had them in 74, pickups in 75. You want one with a vacuum advance, which was into the 80's. Whatever you use, if you want performance, you will want to recurve. These distributors are getting hard to find, and are commanding a premium price. The last one I bought was $25, but that was over 10 years ago.

Biggest issue I have is with the large cap. Somewhere I had an article on converting a small cap from a 2.8L v6, but I cannot find it.
