Re: V6 vs I6 GH HEI difference. please help identify
There are two versions of the GM HEI I6 distributor. One external coil, the other an internal coil. The internal coil version has a ground wire to the coil, other then that they are identical. I am running an external coil from an 86 Astro on mine and a dist cap and rotor from a 75 292 CID truck.
Of course I am running fuel injection in closed loop mode, but that is another story.
