but never got it to run good. On the bottom it's ingraved XS274510 and UH6146.
Greatful for any hints.

Got the tip from a friend that it could be a Comp Cam. Anybody senn these numbers before?

Camshaft is a CompCams XS254S, mechanical camshaft although it was hydraulic lifters in the engine.

The Comp xs274s is indeed a flat tappet mechanical camshaft.

The specs are :

274*/280* advertised duration
236*/242* duration @.050 valve lift
.502/.511 lift with a 1.5:1 rocker ratio
110* LSA


It should work well with 9.5:1 static compression and a 2800-3000 stall speed

Thanks Ron, one can always count on you!! Did put a littlebit mildercam in it, together with the
4,88 gears it was not that fun to drive it. Will have power enough in the Charger if I feel needed
to go fast!
