that 7200 operating range for the cam is likely sized based on a 440, for an SR the lift is a little short for that @.050 duration but it'll make plenty of torque and power. It's probably a street endurance grind which to me is perfect because with a wedge head the peak lift isn't as critical as long as your in the sweet spot of the head flow (85-95% of peak).

Should work great, I'd look at the Indy dual plane (383man, BSB67 and myself all run them on ours ) and look close at a custom calibrated pro-systems 1000HP or similar. 10.86:1 calc'ed should be fine and a little lower than what I typically run on a 500 incher.
