To add to the confusion you can also throw the Lunati Voodoo hydraulic flat tappet lobes into the mix....
Part Number: 10510704
( Previous Part Number: 60904 )
Advertised Duration (Int/Exh): 276/284
Duration @ .050 (Int/Exh): 233/241
Gross Valve Lift (Int/Exh): .504/.527
LSA/ICL: 110/106
Similar .050" duration as the UD 288/296 & Crower 60919 cams but with less seat timing and additional valve lift. And some will suggest the Voodoo lobes are quieter than UD grinds, and especially the Comp XE lobes.
