Here is a little info that might help in making your cam choice. Cam Change: Typical effect
More Lobe Separation: Wider powerband, more peak power,
smoother idle
Less Lobe Separation: Increased mid-range torque, faster
acceleration, narrower powerband
More Duration: Powerband moved higher in rpm range
Less Duration: More low-end torque
More Overlap: Improved signal to carburetor, lower fuel
efficiency, potential for reversion
Less Overlap: Improved low-rpm responsiveness, better
fuel efficiency, engine may run hotter
