Chevy V8 Distributor W/Lock Out Advance

The MSD IGNITION Chevy V8 Distributor with Lock Out Advance is a high-performance ignition component designed for serious engine builders and bracket racers who require precise timing control. This pro-billet distributor is engineered to eliminate mechanical advance curve variables by locking out the advance mechanism, allowing tuners to set a fixed ignition timing strategy tailored to their specific fuel, compression ratio, and RPM range.

Purpose-built for Chevrolet V8 engines, it replaces the factory HEI distributor while maintaining OEM-style terminal compatibility for straightforward installation. The distributor features a magnetic pickup ignition system that delivers a consistent spark signal independent of engine load, eliminating the inconsistencies associated with points-based ignition. Its locked-out advance mechanism prevents centrifugal weights from advancing timing at higher RPMs, giving the tuner complete control over spark curve programming through external timing control.

This distributor is ideal for dedicated race engines, drag racing builds, and high-performance street applications where locked timing provides a competitive advantage. It is compatible with gasoline and methanol fuels, ensuring versatility for various performance setups. The pro-billet construction ensures durability under sustained high-RPM operation, while the slip collar design simplifies rotor alignment and maintenance.
