Consistently, a single pattern cam (almost) always makes more low end torque over a split pattern. The split pattern was thought up and designed to help a weaker exhaust port which also helps extend the top end punch.

If you look at the old MP cam grinds like the .528, .557, .590 they are all single pattern cams
