Rocker Arm Ratio

Bill Diehl · 12-26-2013, 08:51 AM

As long as it does not exceed what the spec says at the valve....I don't see a problem.

Of course one could manipulate the valvetrain.....larger cam diameter, offset lifters, change the phasing, relocate the attachment point of the rocker, change the ratio, longer/shorter valve stem, ect. all in a quest to build a better mousetrap.

But, at the end of the day ,if the lift at the valve SEAT does not exceed the spec called for...who cares?
