Hard to beat a 96-3 for short track racing. 07-3 works well also. Properly setting up the cam is probably more critical to your application than deciding between a couple particular grinds.
Consider valve overlap, centerlines, ignition timing, strong fuel signal in the carb, and pipe choice into your equation as well.
I have found that the cam that creates the best HP on the dyno works well no matter what size track (large or small). I listed the 96-3/00-5 combo because it made great power over a wide range of spring pressures.
