63 Dart 383
Been there, done that! My first Mopar was a 63 270 Dart in 1968 that I swapped out the /6 for a 66 273. Luckily I bought a 66 Dart that was complete, but wrecked. I used as much of the 66 stuff as possible to do the swap. The reason being is that the 63 was never designed for any V8 and that includes the steering set up.
