1.7 rockers effect the lift ratio, not necesarily the total lift.

the reason for longer ratio rockers is to lift the valve faster of the seat, they arent used for more lift.

lift is easy to grind in a cam, a lobe face that is radical enough to lift the valve quickly is not easy in a hyd, or ft cam.

Hey dirtrace, valve lift is lobe lift x rocker arm ratio, so the greater the ratio the greater the v.lift.
