1 One cam will not do everything well, you may have to make tradeoffs. 2  In other words, if you want to drag race with a cam that pulls at 6800 rpm, don't expect the engine to lug a trailer around at 2000 rpm or vice versa. 3  Cams have power bands, sweet spots or RPM ranges that they work best in. This power band or sweet spot does not mean that the cam will not work above or below this range. 2  If, for example, the sweet spot is rated at 2000-5700 RPM, the engine will still produce power above 5700 RPM (at least ours will), but above 5700 RPM, the next larger cam will produce more power.
