Big Block Chevy V8 - Internally Balanced396 400 402 427
This damper is unique in our line in one respect, it is 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.
