Motor Swap on a 63
No, the wiper motor is in the same piece of real estate that the distributor needs. You can modify the firewall to duplicate the 64-66 firewall where the wiper motor mounts differently inside. There's also a member here who has shortened his distributor to work. That's a little more in depth than most people can do at home, but it was really cool. Option number 3, which I am rather fond of is simple. Put a V8 in there that requires no firewall or distributor mods at all. A 383. Distributor in the front, bolt in swap with the right mount kit, 68-69 B body HP manifolds are almost a drop in fit. Why there aren't more big block early A bodies I have no idea. It's so easy to do.
