Founding Member. The good thing about the 1.7 rockers is that it takes the b-cams.480 and turn it into a lift of.510. SO you will get more out of the cam. I know this because of this Forumla To calculate the affects of increasing rocker arm ratio, use this formula: Lift with new ratio = Lift with stock ratio X new ratio / old ratio For example. The Ford E303 cam is a Crane 2040. Here are the specs for the 2031 with 1.7 rocker arms. 214/220 @.05 276/282 Advertised Lope Seperation.
