Pulled camshaft today and have no idea what it is... I bought a new one but I am curious as to what was in the motor originally. All I can find on the cam is a CWC, CMC, 1539, 1.5, and MTCI. Anyone have any idea what this might be... Thanks

CMC may mean Camshaft Machine Company, but other than that I have no idea.

You can at least determine lift like this: Using calipers, measure across the smallest part of the lobe (width) and then subtract that measurement from the largest part (height). Then multiply the result times 1.5 to get lift at the valve.

For example, lobe width might be 1.100" and lobe height 1.380". So, 1.380 - 1.100 = .280 x 1.5 = .420" lift at valve.

BTW, on a small block cam, the front two lobes are exhaust, the next two are intake.

With the cam in the engine you can measure duration and lift using a dial indicator and degree wheel.
