Cam Lift on Solid Cams

You mean those lifters with the tiny laser drilled hole? There a new idea on the market, so "Needing" them is a option.

I have a cam be way off from many manufactures.

FWIW, I have a Comp solid lifter cam in my 360 now with .022 lash. The cams lifts is .525.
525 (lift) - 022 (Lash) = 503 actual (In theroy it should be by the numbers at least)
Measured .510 at the valve. Also, rocker arm geo. isn't perfect nor is the contact patch and travel perfect. The Edel. heads still need some work in the valve area and there stem height.
