He said stock create engine so that would be the MP Hyd. roller cam, 288/292 ... I forget.... low .500’s in lift..
@autoxcuda could be of a bit help here since he auto crosses is car. He (IIRC) uses a solid flat tappet cam a good bit smaller. If you run at a track you could perhaps discuss the cam needs on such course(s)
My direction would be for a smaller cam for more torque.
