• The included distributor mandates a full twelve volt ignition source bypassing any original factory resistor wires to guarantee a powerful spark.

Installation, Break-In Oil & Priming Instructions

Even fully dressed engines demand careful pre-lubrication and heat cycling to ensure long term mechanical reliability.

• Before firing the engine builders must utilize a specialized tool to prime the oiling system manually ensuring fluid reaches the upper valvetrain completely.
