I think he means 3.73:1, if not I guess he's running 60ft only

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. Life is more fun when you have a child-like mind like I do
