Here is what I found about my installed cam..
Intake side lift .260 x 1.5 rocker= .390 lift,
Exhaust side .258 x 1.5 rocker = .387 lift.
So its higher then a stock cam..I have to find out what cam number/maker it is for all the information.. So what do you guy's think about it. Thanks again for all your input!

That's more than the stock cam lift, but less than most performance cams. IIRC, there was a Crower Special Studebaker grind with approximately that lift:

Crower E-32794 Special Studebaker grind
260 duration/.392” lift@.014” clearance

Actual cam lift for stock cam should be .2668 (rounded off). To calculate valve lift you have to account for valve clearance. So (.2668*1.5)-.020 = 0.3802 valve lift.
