My Jones Cam Recommendation

on solid cams .020 or.050 are deceptive and can get you in trouble as lash and intensity make a big difference
Experience, Cam Doc , SAE method for seat timing .200 .300 for power
remember many advertised are marketing driven
does the designer work trying to create the perfect mathematical lobe to a zillion decimal places for his new cnc grinder or does he model valve motion and head flow ?
