I bought a few salvage yard LS engines. Only got burned on one. It was a LS6 that was supposed to be 40K miles but after some disassembly it was more like 140K mile rode hard and put away wet. I kept the engine but the local salvage yard gave me a big discount. They didn't want a marginal engine back. I totally rebuilt it and it still runs strong in my 98 Wrangler.
I try to buy the low mileage engines. Check with whoever you buy from the warranty as it applies to installing the engine into a older vehicle. Most won't give you any warranty.
I've found car-part.com to be my go to web site to search for car parts. You can search locally or nation wide.
Just a tip when you get your 5.3. Pull the valve covers to see what the top of the heads look like. Also pull the pan for lower end inspection. Do it right away. Do a compression test.
