I can get that from a 42 yr old '70 340 duster by just giving it traction. Just how far did GM get? I thought certain Camaros ran that time in '69? Oh, sorry, forgot about the corners.... lol
what that 40 years got GM was a well rounded car that does a lot of things better.
they now run better in all different weather, more comfort in all weather, stop better, corner better, are safer, and get 3 times the MPG, and not to mention fit and finish is light years above what ya got in 69..all that while weighing what 1000 pounds more?. like i said they were built to do many thing good and that is what they do.
