It's possible that cam will work quite nicely at 2500 rpm. ANOTHER big problem I have with a typical T5 is the ultra low first gear, when you combine that with a 3.5 or especially a 3.7 it becomes all but useless. You could use 2nd gear to start out and very likely get BETTER 1/4 mile ET times using 2nd to launch! 1st becomes a 'stump puller' tractor ratio, a real tire smoker of a ratio (might be fun  ).
WATCH out when you grab 2nd gear in a corner even with LIGHT throttle, it will break the tires loose and swap ends on you in a heart beat. I know, I used to run a 3.5 rear with a T5 and Goodrich TA tires, whew, what a lousy combination for traction that setup was. I 'spun out' THAT car with it's measly STOCK 302 more often than I've ever spun my ERA with twice the horse power. The ERA has some fat tires, great traction and a MUCH higher 1st gear ratio. That all adds up to 'control'.
Myself, I'd shoot for gear ratios eqivulant to a wide ratio or close ratio top loader with a 3.5 rear gear and a .8 OD AND some 'sticky tires' (for safety). I think that would be the perfect all around gearing setup.
