700R4 with a 454 is a joke. Not an option IMO.

In most cases it will, but not with big blocks.
I get 9-10 all the time. It doesn't matter if I am driving empty, towing 8,000 pounds in third gear. The same is true with my rollback. It gets 9-10 when empty(9,000 pounds) and gets the same when fully loaded(15,000 pounds) and in fourth gear. That has 4.88 rear axle and an NV4500.
You can look on this site and many others and see what kind of mileage big blocks are getting.
You don't buy a truck with a big block for mileage. You buy it to haul/tow.
