this is how they read on the firewall end of the cam

cam#1 . cam#2

4710 . 7812
4 22 . 4 06
7031 . 7193

are these from some independent grinder stock cams? isky, comp, & lunati do not recognize the numbers

 

can i buy a vowell? anything i can explain better? any other numbers somewhere?

 

If you don't get any good info on here you could look around for a speed shop with a cam doctor. They tested mine for $12, gave it back with all the specs.

Goodluck.
