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. (IMG:http://www.914world.com/bbs2/html/emoticons/sad.gif) --DD |
