I came across 2 cars tonite- 69 Dart and 63 Belvedere. Not worried about looks. With a 440, both cars weigh about the same +/- 50 lbs. This would be a strip car that can still be driven on the street. I've got a 440/500 HP with a 727 w/2.75 1st with TA "J" converter and 4.30 rear. Shoe horned BB in the A or a bit more room with the B body? At present, I have no preference. Who has what and what ones is better, if there is such a thing?
