I just thought of a couple of more questions on the 744/2802 cams. Even tho the 2802 has a lot more lift, can it get by with less spring pressure than the 744, because of having a smoother profile, rather than the "bullnose" lobe, as someone described it ?

I assume this "bullnose" is similar to the NHRA Stocker grind profiles, just not as pronounced. Is this correct ?

What exactly was the higher spring pressures that Pontiac used on the RA3 and SD455 engines, with this 744 grind cam ?

The popular spring for many Pontiacs seems to be the Crower 68404's. So are these springs strong enuff for a 744 grind, or will it take something stronger ? Will they work on the 2802 ?
