Stock Distributor and Coil?

If wiring from scratch, it would be a bit easier to use a GM 8-pin HEI module w/ the GM coil & cable that goes with it. That would give a slightly stronger spark and you can toss your ballast. Many posts on that. TrailBeast (above) sells a kit w/ new parts if you can hit a junkyard (85-95 GM V-8).
