Distributor, MSD, Pro-Billet, GM HEI

Chevrolet Small Block/Big Block Pro-Billet HEI Distributor by MSD®

A billet housing, performance module and cap-mounted coil upgrade the conventional HEI layout.

This MSD® Pro-Billet HEI distributor combines a CNC-machined aluminum housing with a QPQ-treated steel shaft, sealed upper bearing and lower bushing. The magnetic pickup works with the integrated performance module and ignition coil, so a separate ignition box is not required. Adjustable mechanical and vacuum advance let the timing curve be tuned to the engine. The coil and module combination is specified for high-rpm HEI operation, while the cap and rotor complete the assembly. Select the desired cap-color version and verify distributor clearance before installation.
