Correct, the power gains arent that great that you would swap out an equal cam. In a race motor where you are looking for the optimal performance and another 2hp means a lot, yes.
Anyway, thats 620 rear wheel hp? NICE!!! Figure 15% loss, thats 713hp at the crank. GM left a lot in that motor....a whole lot. This is the main reason I dont see them going to a SC motor in the future unless its cost effective to do so.
