Rocker Arm Part Number?

[michbc3]

When looking for some replacement rocker arms, I checked NAPA and Summit. Both list Sealed Power part number ZR947. That can't be it as the pictures show a shaft mounted rocker arm - probably for a Buick I'd guess.

1. Does anyone know the correct Sealed Power part number for our TTA valvetrain?

2. Are adjustable roller rocker arms available for our heads? If so, who makes them and what are the part numbers?

Best, Bob

I dont know the Sealed Power number for a stock rocker (last time I needed some the dealer had them), but as for an adjustable roller rocker Harland Sharp is the only compalny I know of that makes a set for our heads. I dont belive there is a part number but give them a call and they should be able to take car of you.

The GM stamped steel rocker arm is serviced as a kit,per.

Group 00.333 part # 12332785 and it would come as the arm and pedastal....if you can find them.

Though I picked up a few stock rocker arms for my TTA original engine, I purchased a set of Harland Sharp rocker arms for my new TTA engine. At first I thought that the rocker arm ratio for the TTA was 1.55. That was a bad assumption. It's very close to 1.7. So that is what I ended up getting. These have a 0.050" adjustment range. Randy Sr. at Harland Sharp is great to work with and it's notable that he builds these things for such a limited production car.
