Chrysler SB 318/360 V8 Pro Billet Distributor

This Pro Billet distributor is built for the Chrysler/Mopar LA small block V8 family — 273, 318, 340, and 360 CID — using a magnetic pick-up trigger with mechanical-only advance for precise, consistent timing control in dedicated performance applications.

This distributor requires a separate ignition box (not included) and an external coil rated at 35,000+ volts (not included), along with a 12-volt electrical system with an alternator. It is not compatible with generator-based charging systems or vehicles still running a ballast resistor in the ignition circuit — the ballast resistor must be removed or bypassed before installation.

Engine fitment covers the Chrysler LA small block — 273 (4.5L), 318 (5.2L), 340 (5.6L), and 360 (5.9L) CID — commonly found in the Dodge Dart, Challenger, Ramcharger, Plymouth Fury, and Chrysler Cordoba. This distributor is not designed to fit Chrysler Magnum-series engines.

 

Mechanical-Only Advance: What This Means for Tuning
This distributor uses mechanical advance only, with no vacuum advance canister — a common setup for dedicated performance and race applications where a fixed, RPM-based advance curve is preferred over a load-based vacuum advance curve.

Performance Benefit
The magnetic pick-up trigger and mechanical advance combination is built for dedicated performance and race applications where precise, adjustable timing control matters more than street convenience features like vacuum advance or a self-contained coil.
