anyone know fo sho?
Full Version: What are the stock rocker arm ratios?
anyone know off hand?
It is "about" 1.3 for both. But tolerances on them are not the tightest, so the ratio can be closer to 1.25 than to 1.3... Though I don't recall offhand hearing of one that was significantly more than 1.3?
Anyway, it varies from rocker arm to rocker arm.
