Points have worked for a 100 years. If you want HEI, go with what BBV6 said. A brand new genuine GM distributor, then modify slightly and make/have made/buy the bushing. Search on here to read all about it. There is a fellow member
WE7X@aol.com who may still make the bushing. See our Performance/Jolly
Tip.
You need a lathe and a drill.
