My best friend Rick, (RIP) ordered a new 1972 340 Duster, 3.23 SG, 4 speed. We took it to Dragway 42 early spring 1972 when it had about 5000 miles on it..
He only made one pass and it ran 14.51. That was pretty good for a totally stock 1972 car except for G70-14 Pokyglas tires on the rear. His mom had a Goodyear credit card, LOL.
