I am playing around with the idea of the HEI ignition module swap inside one of our original orange boxes. Done a lot of reading it seems pretty straight forward. The biggest thing i have read, in order to take full advantage of this swap you need a coil that can handle a constant 12v. Unlike most coils that require the ballast resistor on our fire wall to drop working voltage to 8-9v range. I know most of the articles say to use an E-coil, but I am trying to keep it looking stock with a canister style coil. Wondering if anyone has found a coil that can handle the extra juice.??
