ROCKER SETUP IS SOLD!
CAM IS SOLD!

1.52 Pro-Mag Roller Rockers are still available.



Oh, if needed I have a set of (8) 1.52 ratio pro magnum rockers, so I can give you a split set if you need one with your setup.

whats the lift with 1.52 rockers? I have a set of 1.6 rockers, but my springs are for .540 lift i believe. Would you trade the 1.6 rockers for the 1.52?

To find the lift, divide by 1.6 then multiply by 1.52 .

BAM is right, the equation is Cam Lift * Rocker Ratio = Actual Lift

So you divide out the 1.6 rocker ratio to find the cam lift and then multiply it by the new rocker ratio.

with 1.52 rockers it would be 0.517/0.526 The problem is that I only have 8 - 1.52 rockers not a full set of 16. These rockers are 7/16 NSA.

You would be better off getting a new set of valve springs. If you are swapping out a cam then you are most of the way there on a spring swap.

True, but they are a set of tfs heads with only 5k miles on them. Let me see what a set of springs would cost, but it still may be a bit much on the duration for ca smog.

This cam has 7 degrees of overlap at 0.050 lift. I would NOT recommend it for a cam if you want to pass smog testing.
