PerTronix D1070 Flame-Thrower Black Cap Race Distributor HEI for Chevrolet Small Block/Big Block

I enthusiastically purchased this Pertronix HEI in hopes of enhancing the responsiveness of my big block Camaro. Unfortunately, I was not able to map the advance curve. I switched springs, and could not get more than 29* @ 3500 RPM. Pertronix customer service reps were very friendly and tried to assist, but were not able to resolve. In the end, I switched to an MSD 6AL system with the MSD billet distributor. That did the trick... approx 14* initial advance, and fully open at 32* @ 3500 RPM. Runs great.
