how do i tell what cam i have?

Is it a factory cam, or some aftermarket one? I can't imagine any regrind that wouldn't have markings on it to identify the grind.

If it's a factory cam, just remember which car you got it out of, 'cuz there's no markings to identify them. :-( I hear tell about a machine called a 'cam doctor' or 'cam dyno' which can tell you all the specs about your cam. Then you could cross-reference it with the known specs in tables on thedodgegarage.com.

its a brand new enforcer 1 head from forward motion. its not out of any car. its new. the cam came with the head and it doesnt say what cam it is.

oh. I didn't realize that their Enforcer heads came with cams. In that case, I'd advise you to call 'em and ask which cam they gave you. I'll bet that it's their mildest regrind.
