I think he means 3.73:1, if not I guess he's running 60ft onlywikd69 wrote:7.73 ? As in 7.73:1 gears ?jaspermaggie wrote:not much doing a rebuild. 355 or 383.

Well, I've known people running 6.30's, etc., though I can't imagine that sort of gear reduction. I don't have enough time on the track to know what's typical with different classes and/or engine/trans/gear/build combo's. I'm constantly amazed by the stuff I see here on the forum.
