Re: HEI Conversion-Sudden Death

I run a 292 with a GM HEI. I have an AutoSun tach. Never had a tach related problem that wasn't simple, like a broken wire under the dash. [A loopy ground wire got caught in the clutch pedal spring and was torn loose.]
I power the HEI Coil with a red 12 ga. wire from IGN Unfused in the fuse block.
Still running an external voltage regulator, too.
