So this is my first post to this site. I have a 72 Fastback that I put a 429 Cobra Jet, bored and stroked to a 472ci. The engine was run on a dyno a couple of years ago. The problem I am having is I am fouling plugs almost immediately when I run it. I marked the distributor from where it was from the dyno shop so I believe it is in the same spot. I am thinking that I have an ignition problem because the carb has not been changed or adjusted since he dyno. I thought I might have hurt the ignition module because I shorted out the starter solenoid when I was debugging the wiring. It has a Pertronix distributor and I tried a new ignition module, but same results. It just acts like It is not getting voltage to the plugs. They are pitch black and dry. Any thoughts ?
