Wanna have some fun? Put a 428 crank in a 455 block with some light pistons and longer rods, good flowing heads and a nice cam and get ready for power out to 7000+ RPM.

I did the opposite about 22 years ago and put a 428 crank in a .030" 400 block, turned down the mains. Basically a small main 433 CI engine. I ran the snot out of that for years. I liked the combo for the most part.
