Any instructions on doing this modification available? Sounds like a great mod!
I'll get around to writing a tech tip on the procedure, hopefully soon. It involves mounting a GM pickup coil to the stovebolt distributor housing and fabricating a triangular reluctor from plain steel plate to trigger it. The GM HEI module is mounted remotely, even under the dash away from engine heat and weather concerns. A fancy coil isn't needed- - - -just a MOPAR or Ford electronic ignition item that resembles a stock stovebolt coil will work as long as it has the right primary winding resistance (about 0.5 Ohms). Right now I'm dealing with some family medical issues that have me pretty much limited on shop time and other projects. There is some machining and fabrication involved that might be a little beyond the backyard tinkerer's capabilities.
