I didn't know you were aiming for 440 cubes. A 4.155" x 4.000" will get you 434 but I really don't like the thought of a 4" stroke with 2.250" mains. Lots of stresses there.
I would either go for an off-the-shelfer, like a 3.5" stroke, or switch blocks altogether. I know that you said you were working with a $5200 block....is that aluminum, or just the price of a cast iron block to your door? I can get you a new Dart or Ford Racing block to your door for considerably less than that....probably fully machined.
With a 4.155" x 3.500", you'd be at 380 cubes.
