The biggest problem with the 4in bore is the block Running Hotter along with thin walls Just really doesn't make for a good daily driver.In my personal oppion. As to how much hotter it would run That i don't know. But as for testing the Block Yes that i'm sure could do to Hope for the best block to bore that much. which would let you use maybe just about any v8 piston. But if i do remember right the 327 is the better choice.
