I'm using intake centerline method, when measuring at .050 valve lift does my dial need to be on the lifter or can it be on the valve retainer(factoring in my 1.5 ratio rockers)?
I keep coming up with the same TDC but @ .050 (dial on the valve retainer) I'm not getting anywhere near the 106 centerline on the cam card.
Any help is appreciated, Joe

if you have a true 1.5 rocker multiply .050x1.5 and thats the cam lobes .050 number at the valve. you cannot check duration, lift, or anything for that matter using a hydraulic lifter. best, and simpiliest is check at the lobe.
