Put it on a stand and tear it down for inspection/measurements.

the first part of a rebuild is to tear down the engine.   send the block to get it magnafluxed and/or bored.  order parts depending on how much  bored. Send heads out for valve/seals.  Get all parts back at about the same time and have fun with a toque wrench. Nuttin to it, huh?

That doesn't look too bad - I've seen junk yard motors much worse than that brought back to life ;D

I would use a new intake though

You can clean all of that up. Send your parts to the machine shop for a hot tank and bead blast the intake.

i think it takes a 400 crank to make a 350 a 383 so could i make this 383 a 396 some how?

A 400 c.i. Crank and a matching 400 c.i. flex plate/flywheel.  There is also a minor thing about the piston rods needing milling or shaved slightly for clearance.  They sell these complete sets from summit or jeg's.
