The always elusive CAM question..

I agree with ya we need to know the exact CR before you can decide on cam that's the situation we have but I would like to know ruffly the cam spec first and let that determine my CR, stall and final gear ratio than the other way around. And yes I think you should know what cam your gonna run before machine especially on more radical ones, piston to valve clearance, CR and valve spring heights etc... Are gonna be effected by cam choice.
