Proflow Distributor, HEI Street Series, Vacuum Advance, Black Cap Dual Module Plugs, SB & BB For Chevrolet V8
Proflow Economy Street Series HEI Distributors feature compact design with Bosch style module, cap & rotor. These units offer calibrated advance curves that are optimized for maximum combustion efficiency, and the elimination of detonation damage and throttle ping. The distributors offer longer-term durability and a higher voltage spark that permits a bigger spark plug gap, resulting in more power and reduced plug fouling.
