HEI Conversion Question and Holley 2280 Lingering Issue

It is a good idea to twist the p/up wires, but not mandatory. Check for p/up air gap, should be 0.008". Make sure there is an air gap for each reluctor tip. Contact between p/up & rel tip results in no spark on that cyl.

Keep the p/up wires away from: coil - wire, tach wire, high tension leads. Too close can induce no-fire or misfire.
