As long as you stay with Iron right? The Aluminum DART has a recommended max bore of 4.165 (.020 less than Iron), hence you are limited to ~450 max CID on the Alu block. Just asking so I understand.

You could get up over 460 cubes with the aluminum block as well. Dart says they will allow 4.165" x 4.250" with those blocks, which would be 463ci.
I've never had to take any of these blocks out to as far as we're talking. I generally do the 4.125" and 4.155" flavors. As I said, sometimes customers get hung up on numbers and instead of a 427 (4.125" x 4.000"), they'll want a 434 just to be a little different.
Rod, yes, at some point you would look to a big block. I wouldn't necessarily look to an FE, but the 385 series engines will make unreal amounts of naturally aspirated horsepower and torque. Of course it all comes down to what you want, what you're doing, the style you want, etc.
