and MOPAR Cams
Sorted by MOPAR Duration for DC/ MP and factory cams with SAE duration (.006 at the valve or .004 at the seat with 1.5 rocker approximately placed in the list

all are in the same order but the board software will squeeze out white space
Lift (lobe lift) adv or .004 Duration - seat timing - at .050 timing LCA icl excl



Crane .904 lobes H2 street and strip H3 have higher acceleration = will need more spring

Compare Crane .904 lobes- which are fairly mild with the Detroit Grinders Grinds
