This was the cam spec you gave to mustangjp for a solid lifter engine with 2v heads. Would you likewise increase lift on a hydraulic cam grind for an engine with 2v heads or should I just stick with your hydraulic boss camshaft grind.
One last question, what do the lobe numbers mean #H295/324, H285/324, are they Bullet Cams blank camshafts for grinding?
Lastly just wanted to say I enjoyed reading your cleveland buildup stickys, great detailed information on an engine I think is special in ford engine line up. Thanks Mark
