Stage 3 HC will have most of the power at the end of the RPM range, but like hoser started to mention, HP doesn't =faster. You could have any cam you want, when you change gearing it effects whatever the motors supplying in that gear. Yes stage 1 power peaks lower in the rpm curve, stage 3 power peaks at the end of the rpm curve, Stage 2 is basically the HRC cam's twin brother, he just wakes up a little quicker. But, you take any of those cams and change gearing your changing the ratio of power to RPM. If you have TALL gears you wont be in that gear long before rev limit and shift is needed. So, if you just want to be the fastest out of your bunch, with the info you've provided (no distance to get to speed etc) I believe you ll want as few teeth as possible on both sprockets. There is limits as the chain has to have the right amount of adjustment or your chain will be too long to tighten. I'm no pro at any of this, just going off what I've learned over the years. Also sent a link to gear ratio/speed calculator which allows you to enter a few parameters (tire size, sprocket teeth #, etc) and the calculator will throw back a graph with a lot of useful data, for you its top speed in any one particular gear with your entered setup. www.gearingcommander.com

Also, changing cams can lead a lot more possible mistakes being made during dis-assembly re-assembly, and the time to do so, compared to swapping sprockets just to show your boys what time it is....Make sure your running low psi in your shoes for high speed runs. The psi will almost double spinning that fast in theses little tires which effects circumference, which can lead to wrecks at top speeds, especially on pavement/asphalt
