When I do a swap, I don't want a 350. I want a 5.3, 6.0, or a 400ci.

You can get a 5.3 from a junkyard here for around $500
But for a 6.0 they want more than twice that. Probably because 5.3's are a dime a dozen now.

Cory, a bone stock 5.3 with just a good tune would make that S-10 run like a raped ape. My 5.3 can scoot my big ass Burban and I know my truck weighs more than twice as much as your does.
