You might have a .280" lift measured at the cam lobe with a 1.5 rocker ratio for .42" lift measured at the rocker arm.
It may be packing' the same duration numbers as a .450" lobe lift / 1.5 RR roller cam that measures .675" at the rocker.
That's .170" difference in lobe lift. Picture that in your mind.
And it really is fun on test-n-tune night beating the back-halved, roller camed, dominator equipped big engine with a Stock Eliminator car!
