Factory electronic distributor so you can set the timing up correctly. HEI control box and a HEI coil. One ignition wire and your done. Best thing I ever did. Some will ***** that it's a GM part. So, it works great. I like to drive my cars.
@halifaxhops has some slick GM module mounts made up to convert slant 6 distributors. I wonder how close they are to working on the standard V8 distributors, point or electronic style? [FOR SALE] - Slant six HEI plates
