1.6

wow fast, thanks i thought it was but i thought it might have been 1.5 also

they vary. i've read anywhere between 1.4 to 1.6 because they flex or something.

Small block Chevy = 1.5
Small block Ford = 1.6
and no, they don't flex. If they did you'd have big problems.

The differences in stock rocker ratios can sometimes differ by .1.....but they're supposed to all be 1.6.
