this is a debate that i doubt will ever end.
for some fun facts,
some of the cars back then were ringers, but only a few.
those old muscle cars also were not high priced for the day. many times for just a few hundred dollars more you could get the big motor.
those old big Mopars, depending on what site you look at were 3500~4000 pounds, they were huge cars. to run the quarter in the 14s or better in a car that big & heavy was, & still is fast. and to think they were doing it on tires that by today's standards are junk is amazing.
back then it seems few cared about aero dynamics, the Vette had it, so did the Daytona & Superbird, but most all the others had the shape of a brick.
