I know a lady that bought a '72 Demon brand new. 3.91 gears. 100% show room stock, except they bolted on slicks, ran 14.20. Another guy bought a 70 340 Duster brand new with a 4 speed and 3.91's. He only added slicks and tried to get a 100% show room stock car with only traction to go 13's and couldn't do it. 14.0's was the best of the best.
