1963 Dart question

I know the 63s were kinda designed around the slant. I actually think that's kinda neato. I also know the firewall has to be modified to clear the distributor for a small block. BUT, what about a big block? A 383 to be exact. I don't wanna hear about exhaust or this or that. Just a simple question. Will the 383 bolt in the 63 without firewall mods since the distributor is in the front?
