GM HEI Distributor Black Cap W/ Coil

The PROFORM GM HEI Distributor Black Cap with Coil is a high-performance ignition component engineered for small-block and big-block Chevy V8 engines. This HEI-style distributor combines a magnetic pickup ignition system with integrated coil technology, eliminating the need for a separate external coil unit. The black powder-coated cap provides corrosion resistance while maintaining the authentic appearance expected in classic and modern engine builds.

Built with a magnetic pickup design, this distributor delivers reliable spark timing across the full RPM range without requiring point adjustment or frequent maintenance associated with breaker-point systems. The vacuum advance mechanism provides automatic timing curve adjustment based on engine load, optimizing fuel efficiency and engine response under varying driving conditions. The integrated HEI-style terminal accommodates standard ignition wires, and the included coil eliminates compatibility guesswork—everything needed for a complete ignition system arrives in one package ready for installation on any Chevy V8 platform.

Builders and engine enthusiasts select this distributor for street performance applications, restorations, and high-output engine swaps where dependable ignition control is non-negotiable. Whether upgrading from a points-based system or replacing a worn distributor, the all-in-one design reduces installation complexity. PROFORM's reputation in GM performance parts ensures compatibility and proven reliability across Chevy V8 applications from 1955 to modern crate engine installations.

The 6.95 lb. weight and compact 8.5 x 7 x 17 inch footprint fit standard distributor bores without requiring custom fabrication or adapter plates, making this a direct-bolt solution for most Chevy V8 engine blocks and modern performance crate engines designed for HEI ignition architecture.
