Pertronix Flame-Thrower Race HEI III distributor Chevrolet SB-BB, non vacuüm advance.

Race HEI III distributors use all new components and 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.
Features:

• New lightweight A384 cast aluminum alloy housing.
• Aligned and honed high quality bronze sintered bushings for reduced friction and extended life.
• Centerless ground corrosion resistant shaft reduces friction and provides concentric operation.
• Flame-Thrower HEI III module uses the latest technology to intergrate multi-spark discharge thru red line plus an adjustable digital rev limiter with advanced active dwell control keeping the module and coil cooler.
• Distributor gear is ground to exact tolerances for tighter mesh with cam (Bronze distributor gear available).
