If you want more than ~300-320 rwhp on an SR then get cams. The flow through the valves with stock cams is in a choked flow(sonic velocity) too much of the valve event at that power level.

You can easily go from something like 320-330 rwhp with something like a 3071R to over 400 rwhp with just a set of "mild" 256 or 264 cams and lose only a little bit of bottom end in comparison to the top end power.

Below this power level there really isn't a reason to put bigger cams on an SR.
