I run a BB-T-70 Q trim with a 3500 stall and I think it runs great on the street. I drive it everywhere weather permitting. Hell I drove it to NY city once (8hrs) to visit CK performance, never skipped a beat. I wouldn't hesitate to go a bit bigger next time, say 72ish. Still wayyy to fast to stand on it much on the street though. People hear you comin for miles.
