If you're not that attached to the truck, it would probably be easier to sell or trade it for another. You should also look into your states smog/motor changing laws. If you really want to, swapping an engine isn't that difficult, you just need a hoist, time, and space to lay everything out. I swapped my 4.3L V6 for a 6.2L diesel in one weekend.
What are you looking for in an engine? Best mpg you can get? Or do you still want some power/hauling ability?

Reality Check
If you're handy with tools , go find a decent running truck with the engine and tranny you like , that's all rusted out or wrecked , buy it complete and have at it ~ remove the hood & radiator , rent or borrow a cherry picker and do it . lotsa labor but not overly difficult , having the junker truck handy means all those niggly little bits necessary to make a good job of it , will be right there .
Happily , GM made the frames standard to suit almost any engine and tranny combo so this is do-able on a DIY basis .
Take notes and be ready to repair / change wiring harness and plumbing etc.
to suit .
