slant cam guessing game...428 lift?

Ok, here are a few specs as far as I can tell. The method they use to get lobe lift must be measured off a foot long lifter on a slant as there is no easy way to mic off the pushrod unless you take the valvetrain off. So I tried a few times and looks like it may be a
.286 lobe lift (.429 at valve) intake and
.282 (.423) ex with a
Intake Duration is 217.00 degrees @.050
Exhaust Duration is 215.00 degrees. @ .050
Installed Intake Centerline is 116.50 degrees ATDC.
Installed Exhaust Centerline is 107.50 degrees BTDC.
LSA is 112.0 degrees
Overlap is -8.00 degrees.

intake centerline looks wrong , I thought it would be 108?

dunno, does this look close to anything? Its hard to get the dial indicator to stay on the rocker as there is no flat mounting surface on the head and the pushrods are pretty far from the mag base so its a balancing act. Made a slick degree wheel for nothing: printed out on photo paper, mounted it to a piece of cardboard and hot glued it to a P/S pulley so
I could bolt it up to the balancer. Turned crank with bolt and 30" breaker bar, smooth and easy. Whatever it is, Im running it. Ill use 10/20 lash.
