Choosing the perfect cam for your Harley can be quite daunting, with so many choices to choose from. Here is a quick cheat sheet.
General Rules for Cam Duration:
- 220-235 degrees of duration = low end torque
- 235-250 degrees of duration = mid-range
- Over 260 degrees = top end power
Camshaft overlap durations: less than 30 degrees = low end power
Lobe Separation Angles (LSA): 100-103 degrees = low end power
