did you upgrade anything else with the cam? or is it all stock?

With exaust headers, heads, and an intake you will get the effect you desire. Also, make sure your valve springs can handle the lift of the cam, that's a pretty big lift and some springs may bind.

Do you know the lobe seperation angle? I'd say 109 up won't lope much. Add the intake centerline and the exhaust centerline, divide by 2, see what you get?

that cam doesn't have a ton of lift or duration, thats probably why it has no lope. it should sound okay though. idle it around 800 for the most"lope"
