C'mon Howard. Everyone knows that the only thing better than cubic inches is..........MORE cubic inches. 
Actually, what Howard suggests isn't a bad idea, 427supr. Especially if you're worried about your stock block not being able to handle the extra cubes (although keeping it in the 392-408 range should be fine).
He also brought up a good point about the restrictive sidepipes. You can pick up quite a few HP by changing out those SPF pipes for something better. -But good headers & pipes aren't cheap either.
I guess we could all help you out more if we had an idea of what your budget is. Can you give us a clue? Also, what do you want to do with the car? If it's just a street car (like you mentioned above) then I wouldn't be worried about taking it to 408 - especially with your 6000rpm rev limit.
BTW: If you want "low rpm TQ" like you mentioned above, you need a BB!
