My '72 is also bit louder than I like with 451, big cam and dual 3" exhaust... definitely not a daily driver but I wouldn't call it obnoxious though. :p
Someday at the track, if it goes as fast as I aimed for, I'll have to put a 6-pt roll bar in it (required at 11.49). Hoping to just break into the high 10's which may require using the 150 hp shot. We shall see :)
Oh, today I put a full nitrous bottle in the trunk. I have to remake one braided hose since I added a pressure switch and gauge.
