Black Cap, SB & BB Chevrolet with Coil 50,000v
These Economy Street Series HEI Distributors feature compact design with Bosch style module, cap & rotor.

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.
