Speedway Motors 91012341 Details

If you are racing on a budget, and you need to replace your worn out HEI distributor, this is your best option! These NEW distributors feature with steel gear and mechanical advance for longer starter and flywheel life. Includes cap and rotor with brass terminals, vacuum advance lock plate to eliminate the vacuum module, and an MSD module good to 9000+ RPM. Module features a built-in externally adjustable rev limiter.

Works with cap mounted coil (sold separately) or convert to external coil and ignition box. We have experienced better reliability using an EXTERNAL coil that will withstand the heat & vibration of racing. Includes instructions to simplify installation & eliminate confusion.
