... no wonder I wasn't impressed with its power.
It's a 472ci, all cylinders have about 9.5:1 compression.
Took out a timing light and it flashed on only 3 wires.
I took distributor apart, cleaned corroded breaker points, adjusted a screw, but it still fires on only 3 of them.
What could it be? A capacitor, wires, what else?
