80004 BBC 8 inch Harmonic Balancer Damper

Int. Balance 427, 396, 402

These dampers are unique in our line in one respect. They are the only damper not made to the original factory diameter. The original 396/427 dampers were 7" in diameter from G.M. When the 454 came out, G.M. switched to an 8-inch damper. We elected to use the 8-inch diameter on our 396/427 model to maintain consistency and also because we use these dampers in conjunction with a bolt-in counterweight to create the 454/502 model. Although we list this as a 396/427 damper, it will also work on any displacement big block engine that has a neutral balance rotating assembly. These dampers feature 60° of easy to read timing marks plus engraved marks each 90 degrees of the circumference.
