Reason I ask is I have had some cams on the cam doctor and they come out a tad lower than advertised with some variations among the lobes. Just curious to how yours came out compared to advertised.
By the way that is why I felt safe with a .477" lift on a Vortec head L31 motor. GMPP book says .475" is max for the Vortec head. Motor is running great.
