I'm trying to find out if my cam has a lobe ground down on a cylinder - trying to measure the cam lift at the rocker.

What's the best way to do this? They're stamped rockers, so the dial gauge keeps falling around the indent for the pushrod. I don't have any spare push rods to weld a tab to.

I guess I can wait to get a spare set, stupid magnetic base broke. :rolleyes:

Just take a look at the cam lobe. The lobes are cut at an angle so the lifter will spin. if the lobes are worn, it will be flat on the head of the lobe.

I haven't taken the cam out, yet. :D I'm still trying to diagnose the problem at this point. The one header tube runs cherry red.

Can I even (accurately) measure the cam lift with a hyd. lifter?

I'm just thinking here, but why can't you measure the compressed spring? For example: I've got a .317 lobe X 1.6 = .507. Shouldn't my spring compress this amount?
That may work - I assume they're stock rockers, as long as they're consistent, I'm in business.
