Driveshaft Length
By the way, regarding the V8 in the '63. The first year they offered the V8 in the Dart was '64 (273 only). I have seen two 273 V8s installed in the '63 and it took a bit of modification to the firewall. In the '63 the wiper motor protrudes into the engine bay. See the bump in the photo of my card. This bump gets in the way of the distributor on a V8. You have to remove the wiper motor (you probably won't be driving it in the rain anyway) and cut out the bump and fatten out the firewall. See the second picture of a '64 firewall and notice how flat it is.
