Back when my orig 74 was fairly new I hit a long straight away on rt 80 bout 11;30 pm, 3 lanes, a couple a miles of straight new blacktop & not another car in sight,eased the pedal to the metal & held it as long as I dared, a quick glance at 127, it had a little more but I didn't, backed out gently & went on about the task of gettin home(safely) !
