[Not that it was even legal to do so at the time I owned them] Huh?! Even a 1bbl 199 american with slush-o-matic bald tires and 9" drums should do 90, even if it's gotta work to get there, and not vibrate noticably. My Hornet does 90+ easy with no vibration, and my driveshaft is 1" too short. (I know, I'm an idiot.) My disaster of a 59 American with *flathead* 196ci did 80 with the pedal literally on the metal (I was an idiot -- 20 yrs old :-) though it did not like that one bit thank you. Didn't vibrate that I recall, or at least that wasn't a memorable part of the otherwise unpleasant experience. There are no intentionally built-in vibrations reachable through (ab)normal circumstances. _______________________________________________ Amc-list mailing list Amc-list@xxxxxxxxxxxx http://www.amc-list.com/mailman/listinfo/amc-list
