Best. Day. EVER!
I sold my 2003 with a 4.8l @ 453,000 miles and it had never been opened up. It got 18.75 MPG every tank too! There are reasons the "LS" swaps are so popular. I would do a hair-dried 4.8 in both my duallys if funds allowed. But TPI small block and maybe a turbo later is the currant plan.
