FAST HEI Distributor Advanced Lock Out Kit

FAST is known for performance ignition and fuel system components. This advanced lock out kit is designed to work with GM HEI distributors that don't use a computer to control timing. It's a solid option if you're building a race car or a street machine that needs to rev high and consistently.

This kit helps you set a fixed ignition timing advance, which is crucial for maximizing power and predictability in high-RPM situations. By locking out the factory advance mechanism, you gain precise control over when the spark plug fires, ensuring optimal combustion even when the engine is pushing its limits. It's a straightforward way to get a more dialed-in ignition curve for demanding applications.
