Use car-part.com, I have bought several engines through this locator service, as well as other big parts including my cab.
I second used car-part.com Im right around 2K with my swap Only thing I have left to buy is fluids to fill it up and exhaust shop to rerun my new exhaust. That is with a LS style 4l80e too. I bought my transmission from them and accessory brackets and spent 500 bucks for it.
