I bought a 79 F250 with the 7.5L 460, hoping to eventually make it a monster of an engine. But right now, I'm having trouble with the ignition system. I have power from my coil to my cap, but no power from my cap to my wires. Bought a new cap and rotor, still same problem. I took the cap off, held the rotor connections together, and got power. But when its bolted on, i dont think the rotor is hiting its connections in the cap. I have a feeling my distributor might need replaced. There is a slight up and down play with the shaft on the distributor. Am i way off? I could use some advice before i go spending a grip of money.
