I can tell you've never been in a 403 powered Trans Am. Regardless of their advertised HP rating, the torque is what made them fast. ....and they were fast.
wasn't the little red the faster at the time.. a nicely tuned one would only run a high 14 second quarter mile so the T/A couldn't have been all that fast.. i'll admit when i was young even a 15 second car seemed fast though..
