All cam grinders have a different method of measuring "advertised" duration. For a more "straight-forward" comparison, the @.050 numbers are more useful. Also, each cam grinder has a different "approach" to making power and the corresponding lobe designs or "shapes'. Not all cams are "equal", even if their "@.050" and lift/LSA numbers are the "same".
That being said, what is the brand name and part number? That's the best way to determine if this cam will suit your needs.
