Likely 383 swap-parts advice requested

So, I'm at a bit of a loss here-what kind of water pump housing do I need to drop a 383 in my Scamp? I'm guessing the driver side outlet isn't really a problem as long as I'm using the correct radiator-could someone out there running a B engine take a few pictures of their engine/radiator or maybe some part numbers for what I should start to source for this swap?

Any assistance is greatly appreciated.
