Chevy Big Block 396/427 Damper. These two 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"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.

On a LS with 20lbs boost

I got these for my mechanic. He has a LS with an 88mm turbo on 20lbs. Wires look great and perform great.

Great fitment

Fits great. I wish they had written in BOLD a reminder to put RTV around the coolant ports on the gaskets, because you know, I had to do it twice. This intake looks great and is superior to the Edelbrock, if you want it to last more than half a dozen years. They tie the rear coolant ports together with a passage that Edelbrock just blocks off. Electrolysis goes to work and rots the E-B. Again, this is a much superior design to convert a 5.0 HO fuel injection to carb.
