if you have a cam card you can multiply lobe lift by the rocker arm length. if it says .450 you multiply that at 1.6 and it equals .720 lift or 1.7 is .765

Does that pertain to Solids only, or does it also affect (most likely not as much) Hydraulics? I.E. Valve lifter preload being .050 if you go to .075 would that affect the duration? Also do you have a tech article on this?
Thanks Roger
