I’m using a .670 lift Racer Brown roller cam but the cam is cast steel (not cast iron) and not normal billet for a roller cam. Trying to stay away from a bronze gear if possible. Jim recommended one for a magnum engine (hydraulic roller)
Just get the heavy duty pump drive. The one that has a radius and not a square cut on it. I just bought one from Summit for like 75 bucks or something.
