Chrysler SB 318/360 V8 Pro Series Ready to Run Distributor

This Pro Series Ready to Run distributor is built for the Chrysler/Mopar LA small block V8 family — 273, 318, 340, and 360 CID — using a circuit board module with a magnetic pickup trigger in place of breaker points for consistent spark delivery across the RPM range.

This distributor requires an external coil rated at 35,000+ volts (not included) and 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. Vehicles originally built with a 6-volt system (pre-1956) will need a 12V conversion completed first, or this distributor will not fire correctly.

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.

 

What's Included with This Pro Series Distributor?
This kit ships with 3 bushings and 4 springs for the mechanical advance (allowing the advance curve to be tuned), a color-matched spark plug wire retainer with screws, a black vacuum advance block-off plate, a power extension cable, and a tachometer output extension cable.

Performance Benefit
The circuit board module and magnetic pickup trigger hold ignition timing more consistently than a worn points setup, without the gap drift that develops in breaker-point systems over time. The included bushing/spring kit allows the mechanical advance curve to be tuned to your engine combination, and the included extension cables and hardware simplify wiring and cap alignment during installation.

COMPATIBLE WITH
CHRYSLER SMALL BLOCK "LA" V8
• 4.5L / 273 in³
• 5.2L / 318 in³
• 5.6L / 340 in³
• 5.9L / 360 in³

NOTES
• Fits Chrysler/Mopar LA small block V8 engines (273, 318, 340, and 360).
• Not compatible with Magnum 5.2L or 5.9L engines (1992 and newer) — Magnum engines require a different distributor.
• The 360 was used in passenger cars through 1980 only; truck/van applications continued through 1992.
• Designed for carbureted ignition systems only.
• This distributor is designed for a 12 volt electrical system with an alternator and a performance ignition coil of 35,000 V or more. 
• It is not compatible with a generator and cannot be used with a ballast resistor.
• Distributor gear compatibility should be verified with camshaft material before installation.
