On the early 60's Mopars, the numbers for a B series are on the pad below the distributor. The RB series has a pad in front of the intake manifold. My 64 Fury 361 has a V36. I had a 64 Chrysler with a 413RB. It had a V41 on the pad in front of the intake. V is for the 64 model year. So this 63 Dodge should probably have a U36 for a 361 or a U38 for a 383.
