Help me out here. Working on the subject and can’t figure it out.

9590 cam. 0.426 lift on the card. Adjustable pushrod tool.

I get to 0.426 lift. But the geometry between the swivel foot and the valve is wack. That is shortening the PR.

Stretch out the PR and i get 0.430 lift and almost straight valve to adjuster. The foot is too tight to the 1.7 rocker boss.

Bought some shims to lift the rocker stand and try that.

Question is: why am I so far off the card lift? Does it matter?
