:thumbsup: That Rupp you just built would probably run pretty well too! Dunno if you have been to one of these yet, but there is usually pretty decent turnout of vintage dedicated competition cars running all day not just car club cruisers so its a pretty fun day even to spectate.
I didn't go last year, but the year before they were pretty adamant about legible numbers on your helmet or bike I think, so dont forget a sharpie, or some tape just in case. They never really bothered with that stuff before.
