With the 3.78 gears I have never needed to down shift on any hill with my roadster . It will burn rubber from a stop light if I would let it . Reground cams do cause power loss if the core is worn out . The core needs to have a lobe diameter of 1.225 and a center bearing diameter no less than 1.557 . I measured lots of cam cores before I found a suitable core . Most blocks have wear in the cam bearing area. A new cam with oversize bearings would be better and would compensate for worn block cam bearings . As long as I can find suitable cores and have Bill regrind them I'm happy with a regrind . Lift can be increased by grinding off the heel and using longer or adjustable lifters , that is basically what was done with the B cam .
