Description

Hays Billet Steel SFI Certified Flywheel - Pontiac These SFI-Rated flywheels are engineered to handle extreme duty applications and designed to take the punishment of todays high horsepower engines. Our billet steel flywheels are CAD engineered and precision CNC machined to strict tolerances. For internally balanced engines. Includes a removable black insert that allows this to fit the 2.5" crank and remove to fit the 2.75". Pontiac changed the crankshaft register partway through 1976 on the 350 and 400 engines. The only way to be sure of which flywheel you need is to measure the register (or snout) at the end of the crankshaft where the flywheel mounts. All 455 engines use the larger register. Includes a removable black insert that allows this to fit the 2.5" crank and remove to fit the 2.75".
