Designed in an HEI-style configuration, this distributor provides a practical replacement or performance-oriented upgrade for compatible GM V8 applications.

Before installation, verify engine application, cap and rotor clearance, firing order, ignition wiring, and available accessory clearance. Correct timing adjustment and proper connection to the ignition coil and control components are essential for reliable operation. Professional installation or service by a qualified technician is recommended when application compatibility or ignition settings are uncertain.
