Camshaft: The camshaft must be correct for the year, model, and horsepower claimed for the type of lifter (hydraulic or solid). Roller cams NOT allowed. Duration at .050" lobe lift must be within 1% of factory specs. Lift at the valve must be within 2% of factory specs... - Pure Stock Muscle Car Drag Race rules - link



I've read this before and question the whole validity of this "Certified Stock" claim when the fact is Bob's cam doesn't fit these guidelines. That and the fact that the guys who came up w/ these rules still jack around w/ the cams' LSAs as if that doesn't make a huge difference in how the engines run & idle. It's just a bunch of ego-driven crap to me...
