Information:

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".
