Points ignition systems can easily be replaced, and probably should. I have a Mallory Unilite distributor on my 351W, with a Mallory promaster e-coil. I use the fatty 8.8mm Accel 300+ wires. Wires are like garden hoses, the fatter they are the lower the "pressure" and less chance for voltage leaks and cross-firing. The Uniite is opto-electric, no points or condenser, no dwell adjustment, etc. Check the plugs for weirdness as has been said, but consider a few hundred bucks for the switch.
