Obvious Facts,
The 340 4-Speed {Barracuda , Duster, Dart and Demon} will hook up much better
than a nose-heavy 1969 440 'Cuda.
Also, take into consideration, both cars are running E70 x 14" Tires.
Remember, these are the 'best' times ever recorded for the 'stock' 340 A-Body, not the
general average.
