This MSD Ready-to-Run distributor is a complete upgrade for bulky DuraSpark systems or aging breaker-point models on the Ford 289/302, with a built-in ignition module that requires no separate MSD ignition control — just drop it in, connect three wires, and fire the engine.
Specifications:
- Color: Black Cap
- Distributor Type: Ready To Run
- Engine: Ford Small Block
- Part Number: 83525
The billet aluminum housing is 5/8" smaller in diameter than stock for tight engine compartments and induction setups. Supplied with a black small-diameter cap using HEI-style terminals and a race rotor (accepts 8441 Cap-A-Dapt). A maintenance-free magnetic pickup and precision reluctor trigger the module, and a vacuum advance canister and built-in rev limiter are included. Note: will not fit XD and later Australian 351 Cleveland engines.
