The CAM that you have now should provide peak torque at around 4500 RPM or so. That is already pretty well up there for a street car. The other cam that you are looking at has both more duration and overlap which will raise the RPM range of the motor even more. You are already probably making close to 600 hp/600 ft-lbs at the flywheel. If you're not going to race the car (ie an application where you need high RPM HP), I'd stick with the CAM that you've got. I have a 482FE with a TWM setup from Keith Craft with a cam with duration figures of 242/248 @ 0.50 and around .645 lift and a 112 degress LSA and I'm making 650 hp and a peak torque of 630 ft-lbs at abour 4500 PRM.

If it ain't broke, don't fix it ....
