Can a HEI coil trigger a Mopar ECU?
I agree I'd go with an HEI module "rather than." I tried this in the mid / late 70s and of course had no help, no documentation, and no internet. I MAY have had rotor phasing problems, although I'm sure I tried it both ways. Finally gave up, it would not run correctly. This was an early breakerless Corvette tach drive distributor. I believe someone on here ended up with it.
It had been shortened by a "hack" machinist to fit into a bushing made from an old Mopar aluminum dist. body and to fit a SB Mopar.
