I just attended a 2 day HAMB ignition class and it was great. Bubba's hot rod shop will convert your stocker 235/261 distributor to HEI using machined Chrysler Reluctor and pick up with a GM module. I did mine at the class and then ran it up to 7000 rpm just for fun and it worked great. had a printout of the spark too. I think their cost to re-do it is about $150, or buy the parts and do it yourself.
We also reworked the stock points distributors and the 235's really are good units. I dont mind points so I found it interesting.
After this class, I'll never buy another distributor
