When I was installing the X Cam on my GT with stud mount rockers and using a solid lifter compressed .040", depending on what pushrod length I used the lift at the valve went from the low .530s all the way up to .545... On a cam that has a theoretical lift of .542....
So quit bustin my balls about the exact number out of the calculator.
your dial indicator is probably just off.
if i pull a car 1 foot with a six foot rope or an 8 foot rope, it still moves 1 foot.
