when looking at a cams rpm range the best for torque is the lowest correct? so if im looking at a 1000-5500 rpm range is that pretty torquey? also does the lopeyness of the cam change when you go higher or lower in rpms?

 

Yes, yes, and higher Which cam are you looking at?

 

+1 with starfury, and you have to start chnging valve train gear with a big cam. Be careful.
