A while back I talked with the folks at JE Pistons. You can buy off the shelf pistons with 4.125" bore for only a couple of strokes, and 4.250 was not one of them. On their web site, that still appears to be the case. When I talked with them, they said they could easily make them, but they don't generally stock them. So they had to be special order and custom made = expensive.
Same thing with the Eagle crank. They can do it, but it's a special order. That doesn't seem to affect the price any, though.
I'm not sure what rods you would need, a little shorter than normal, I would think. Eagle doesn't list a package >445 cubes; and that uses a 4.100" crank, and a 4.155 bore.
If you use a Dart block with max bore and stroke, you can get 468 cubes. But the engine is maxed out, the stroke is huge, and the price is even bigger. I thought about it for a while, but then decided not to do it for a variety of reasons - price being one of them.
