get rob aka duster idiot over at slantsix.org to build you a distributor none better. You can send me a stock pump gear or after market gear as a core and i can sell you a gear only. Or i can sell you a gear/pump assy all ready to go.
I like hei. Its cheap and simple, works great and wont leave you stranded. Gets rid of the ballest resistor and gm 4 pin modules are a dime a dozen. Buy a good non-ballest coil and you are set. There is a good write-up over at .org along with a thread on questions and where to get what and how to make it work.
Hope this helps,
frank
