Pertronix II users
I use The Pertronix Ignitor III with my old point dizzy, with the correct recommended Pertronix coil. 383, 292/509, zero deck, TRW .30 over forged FT. I run Pump rec90 with shim .020 head gaskets.
The ballast is in place but bypassed from behind with a solid piece of 12awg to hide it. Timing is initial 18 deg @900 and all in to 36 deg at 2k total. No Knock or fade! 800 CFM AVS Eddy.
3500 Stall 727, 3.55 gear. Cruise great at 185 degree and long idle at 195! Perfect BB A-body Factory Example IMO! With a few Day 2 upgrades!
