Pertronix Race HEI Pontiac 301-455 blue cap D1272

Description:

Race HEI units use all new components and feature an electronic module and coil combination that optimizes spark energy and peak current to the spark plug in the 6000 to 8500 RPM range. Compared to our street or strip version, race units produce 42 percent more energy with 46 percent faster spark breakdown time allowing 48 percent more peak current to reach the spark plug. This abundant energy doubles the spark intensity during the critical one millisecond of burn time. Great for both circle track and drag race applications where factory type HEI distributors are mandated.Flame Thrower Street/Strip distributors have a speciallFlame-Thrower Street/Strip distributors have a specially designed HEI distributor module and coil combination which operates without misfire beyond 7500 RPM.
