rocker ratios
Considering a freshen up on my 302, and replacing the World Product Windsor JR. heads I currently have with AFR 185's. Thought I'd go with some Scorpion roller rockers, and am considering moving from my 1.6 ratio rockers to the 1.7 rockers to get more lift and duration from my not-quite-lumpy-but-not-quite-mild cam. I don't know the spec's or type of cam.
Anyone using 1.7's on their 302? Does this put too much stress and wear on the camshaft lobes? Do I need beefed up push rods? Do the AFR 185's handle the angle shift on the push rods with the contact point on the rocker shifted toward the pivot point?
Curious if anyone has experience and advice. Thanks, DD
