I thought I would post up my budget swap to show how cheap and easily this swap can be done for with a little time and planning.
My truck was a 2000 Silverado ECSB with the 4.3 and a 5 speed It was basically the truck I wanted but I wanted the 5.3 which they didn't make with the 5 speed. The 2wd ECSB with the 4.8 and 5 speeds are super hard to find.
So I bought a 1999 Silverado with a 5.3 and a 4L60E as a donor truck. The body and interior were pretty bad off, but the truck ran and drove great, had 134k miles on it and was inly $1300.
I kept everything I needed for the swap plus some and sold off everything left over. I still need to get a tune done on the ecu to get rid of the SES light for the missing trans components. Without the tune, my total cost into the swap is less than $200
