Except for your thread above, no one has come up with valid reasons why I should use an aluminum block! My car is original and it is currently fitted with a 428!

The aluminum block is lighter (obviously), and can be repaired much more easily than an iron block if your engine builder screws up. Ask me how I know.
In your case, I'd keep the original 428 block, same one they put in the galaxies.
