I went from a 454 to a 6.0 GM gasser. I wouldn't go back the 6.0 does much better lugging my 7500lbs trailer around. I found my 02 no options truck 3 years ago with 23,000 miles on it for 12,000 out the door. Deals are out there you just have to look high and low.
The re-vamped 454 to the 8.1 496 would leave the 6.0 gasser in towing...it'll also love gas stations:), I had the 8.1 in an 01 Chevy 2500 and it comes with the Allison transmission...one heck of a towing machine if you can find one in pretty good shape.
