Modern GM performance projects require ignition components that can keep pace with upgraded engines and demanding use. Whether you’re refreshing a street-driven classic, enhancing a late-model truck, or finishing an engine swap, dependable spark delivery and long-term durability are essential for consistent results. The MSD HEI Distributor is engineered as a direct-fit upgrade that combines factory compatibility with performance-focused construction.
The MSD HEI Distributor (PN 8366) is designed as a replacement for GM V8 applications equipped with the small-cap distributor and dual-connector coil used in 1987–1993 passenger cars and 1987–1995 trucks. Its CNC-machined billet aluminum housing and base are manufactured to tight tolerances for added strength and durability. A dedicated oil passage at the base of the housing helps improve lubrication to both the distributor and cam gear. Internally, a large 0.500-inch polished steel shaft with a QPQ coating is supported by a sealed ball bearing and an extended-length sintered bushing to promote smooth operation and reduced wear. A magnetic pickup and precision reluctor generate a consistent trigger signal throughout the RPM range, working with a factory-style ignition module that connects to the original wiring harness for straightforward installation. The distributor is equipped with a heavy-duty rotor and a late-model red MSD cap featuring brass terminals to ensure strong spark transfer. It carries Marine UL certification, is legal for use in all 50 states, and can accommodate O-ring seals in modified blocks to assist with oil pressure control.
Ideal for street performance builds and custom swaps alike, this distributor provides robust construction, accurate triggering, and convenient installation for GM V8 applications. Backed by a 1-Year Limited Warranty.
