Help convince me to go BB in my Duster?

Sounds like you've all made up your minds, but I'd go for a stroked small block. That is my plan as soon as possible. They are lighter, they will drive better, and you can get a ton of power out of a stroker. Unless, of course, you just want a big block. they do look cool.

Stroked small block is worth comparing. You get big block cubic inch and power in a lighter package. Slightly lighter... Again, a stroked small block IMO IS COMPARABLE to a big block.

What do you mean drives better though?
