Old school muscle cars are nice, but new tech are faster.

Sorry Boss 429 never had the cobra jet motor. It was it's own beast. With fords version of a hemi head, and converted at Kar Kraft.

yeah they weren't as fast as people made them out to be. but definately better than the 70's and 80's

the super duty trans am could run mid 13's bone stock though

recently on the muscle car shootout they got a 104 trap and a 13.7 out of a stock boss with the original polyglass tires so theyre strong runners stock but add some decent tires and a carb that wasnt made for a 302 and hold on lol. Try a 70 chevelle with a 454 ls6 and let us kno with sticky tires they would run 12.6's
