This damper is dimensionally identical to the stock G.M. 6-3/4" damper & our damper has 60 degrees of timing marks engraved!

Notes: Chevy Small Block engines have used three different timing pointer locations. Pre '69 engines have the TDC mark 2° to the left of the keyway centerline. The '69 to '85 dampers have the TDC mark 10° to the left of the keyway centerline. The 1986 to 1991/1992 have the TDC mark 40° to the left of the keyway centerline. All of our SB Chevy dampers, as well as all other aftermarket dampers, use the 10° TDC position. Our 6.75" diameter models have two TDC marks, one that is 10° and one that is 40° to the left of the keyway. If you have a pre '69 vehicle you can use one of the aftermarket bolt-on timing pointers to align correctly with the timing marks on our dampers.

Part arrived on time,good shape.
Works as it should👍

Sound good, fits mediocre

Doesn't REALLY fit a 2010. The muffler tips are recessed into the bumper. It needs a 1 - 2" extension to fit a 2010 well. It bolts up, yeah, but it doesn't actually get the exhaust out past the bumper because the 2010 dimensions are a bit different than the pre-2010 S197s,

Can’t go wrong !

Great FE Balancer. Used on 3 builds, 427 & 2 -428’s.

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.
