Hey folks,
I'm breaking down my engine (289) and just finished pulling the camshaft. Other than measuring lobes and such, is there an easy way to identify if the cam is stock or HP? On the back end, next to the last lobe, there is "20" stamped on one side and "A2" stamped on the other. On the front end, next to the distributor gear, "D3" is stamped on one side and "C3" is stamped on the other (I believe thta's what they say, it's a bit rusted and hard to read.

Anyway, just checking to see if, say Edelbrock cams have "Edelbrock" stamped on em or is there some other tell-tell sign to look for.

Thanks!!

 

It is possible to plot the profile of your cam, but this has to be done with it installed in the engine. You set up a degree wheel on the crank, and a dial indicator on the cam. As you turn the crank, you plot the dial indicator readings. Do this for No1 Intake and Exhaust.
This will give you and idea of both the lift, and the duration of your cam. It takes a while to do, but should hive you the actual info you are looking for.
