I have a NOS Crower that I could not find specs for, and Crower does not keep records past 15 years (so I am told by another person)

I came here for help and the HR guys suggested I use a dial indicator, a set of V blocks, and a degree wheel.

I made a chart, plotting the lift at what degree, plus the duration. (by the way,I was told to use a lifter to get a more accurate reading; so I set up an old Ford lifter on some angle iron)

We also found out that hyd cams have a very short "lash ramp' at the very beginning, compared to a solid cam. Once you figure out it is a solid cam, you can get the valve adjustment specs from those "lash ramp" measurements.

Sounds like a pain, but if you can't get Crower to ID it, then you need to try it yourself

My cam turned out to be a hyd, with .577 lift and 277 duration
