the 400 with the small block bell housing are hard to find, but some where made, 1 year only. The 400 deck height is 10.2", a full inch taller than the Cleveland. If an induction system poking through the engine screen would bother you, forget the 400. The 400 is a thinwall casting and has all the structural problems the Cleveland does, plus there are fewer aftermarket choices with that engine.
With a stroker kit (377 cu.in.), aluminum heads from Australia (CHI or AFD) and a roller cam, your Cleveland can make 500 sreetable horsepower. This is too easy. No need for an engine swap.
