What cam should I get?

OK I don't know what the gear ratio is exactly, I don't know the wieght of the car, I will eventually change the wheels but I think I will try to run the 235/70/15s on the rear. I probably go with a 275/60/15 latter on. The car will see only street use. I might take it down to the drag strip once or twice.

The valve train is the basic Mopar design with the none adjustable rocker arms. I took the valve covers off and checked that out.
I might be just better off now that read these posts to leave well enough alone. It performs well but dosn't have that big cam sound that I like. It does however have a little lope to her.
