I have a 383 that I just picked up that didn't come with a cam card so before I put it in the car I wanted to pull it out and check the numbers on it. All that that it has on the back of the cam is XE 285 HL-10 now seeing that I assumed that it was a comp XE but there are no comp cam markings and I called comp and that part number comes up as a big block mopar cam? Any guesses to what I have... It is a hyd flat tappet
At the chain side it has a EP1 cast in the core

I personally would slap it back in and degree the cam to determine the specs. Degreeing a cam is just about mandatory when you get an aftermarket cam as the cam companies all run their bigger cams several degrees advanced to try and recover some of the bottom end that a long duration cam sacrifices for top end power. If you want top end power you would retard the cam which you can not do unless you know the specs up front.

If you don't have a cam degreeing kit I would recommend buying as large a wheel as you can afford as the little eight inch ones are hard to read and as such are not as accurate as an eleven or fourteen inch version. There is no need for the two foot commercial ones unless you are really old like me and have a hard time reading fine print.

You can print out a free one and try and enlarge the JPEG, then all you would need is a bolt threaded into an old spark plug for a piston stop and a $20 one inch travel dial indicator and a $25 magnetic stand for the dial indicator.

I looked around some too and couldn't come up with anything so Big Dave pretty much covered it - degree it to come up with what you have. If you want to do it and have never done one before we'll be happy to walk you through it. Don't worry about doing it - there's no magic or complicated calculations involved - just basic math. Clay
