So that's it. Why I'm asking this question is because people ask what cam it has? I dont know, some people told me it sounded like a 30-30 cam. Don't know what that is? So I thought it was stock but apparently it was changed with the motor rebuild.

A 30-30 cam is what Chevrolet used in 375hp Corvettes in 1964 and so named since the valve lash is 30 for the intake valve and 30 for the exhaust valve. It's also a solid lifter cam which will be somewhat noisy and have a definite lope.
