I understand that the later 460's (mine is a 1990) had a 1.7:1 rocker ratio. Does anybody know of higher ratio rockers available through the aftermarket?

 

I think Ford Racing has some 1.73. Do a search on Google for 460 rocker arms. I assume your talking about Roller Rockers?

You might try contacting Crane.I think they offer rockers for late-model EFI460s.

 

try cat performance(i think...i know its cat somethin) they have 1.8 for the 460's. we didnt have much of their stock at work, so i dont know what the part number would be. ill try to get their website on here soon.
