Reply to "Mixed ratio rocker arms"

panteradougMember

Yes, I've used 1.8 roller rockers.

My opinion is that you are better off changing the cam for the increased lift and not risk the additional strain 1.8 ratio causes.

Some of the circle track racers like to mix them usually shortening the exhaust side but I have no experience with that combination.

Those guys are always screwing with something to make more torque out of the turns?

I have broken rocker arms studs in the past and the only difference was they broke with the 1.8 ratio.

Incidentally, the 1.7 arm is Chevy and the geometry is wrong for the Cleveland. 1.72 is what you want.
