Experience superior ignition performance with the MSD 8517 Billet Distributor, engineered specifically for Buick V8 400-455 engines. It features a high-output magnetic trigger that pairs perfectly with MSD Ignition Controls, ensuring accurate spark delivery.
The QPQ-coated steel shaft, guided by a sealed ball bearing and a long sintered bushing, guarantees shaft stability across the entire RPM range. The housing and base are CNC machined from billet aluminum for durability and precision.
Fine-tuned mechanical advance is easily adjustable with the included springs and stop bushings, and can be locked out for use with crank trigger systems. The maintenance-free magnetic pickup and precision reluctor consistently generate stable trigger signals.
Finished with an HEI-style cap and rotor, this distributor is ready to install, though it requires an MSD Ignition Control and is not CARB exempt.
