The 80008 damper for 429/460 big block Ford engines is made to duplicate the original damper dimensions. It is 6.7" in diameter and features the standard 3/16" keyway plus an additional 1/4" keyway which permits use on some aftermarket dual keyed cranks. Although this engine is externally balanced, there is no imbalance weight in the damper so it comes as a neutral balance damper.

This damper is 7.5" in diameter and is designed to fit 352/390/406/427/428 FE big block Ford engines. It features the same accessory pulley as on the stock damper but this one is a bolt-on unit and can be removed if some other pulley setup is desired. This may be the least expensive, high quality street performance damper for this still popular range of engines.
