Evo rocker ratio?
|
Getting ready for lifter replacements on 93 EVO, Motor has been modified a bit, milled heads. 065, with screaming eagle high lift springs. I want to replace rocker arms, along with lifters, but stock ratio is 1.625, and I am considering the "Ultima" 1.675 ratio. Would someone way smarter than me please explain? can I use these?? Thanks

You can use them, but we STRONGLY reccomend that you do not.
They are made offshore, and are soooooooo loose, that your OEM hammers will be quieter, and perhaps more accurate as well.
S&S offers a 1.725 that we use with great confidence, when needed/required.
