What makes a cam lumpy?

what makes the cam have that lumpy sound? The overlap of the exhaust valve closing and intake valve opening causes the engine to be inefficient at low speed which results in the lumpy idle. The closer the Lobe Seperation Angle the more the overlap, the more duration the more (typically) the overlap.

What is considered a big camshaft?

It is listed in degrees of crankshaft rotation. When someone refers to a “big cam,” they mean it has longer duration, not higher Lift. … Duration at 0.050″ is the degrees of crankshaft rotation between when the lifter is raised 0.050″ and when it is 0.050″ from its resting position.
