Brought the 5.3 home yesterday. Figured it was time to start the swap thread that way questions can be asked and answered from all angles. The 5.3 is out of a 2000 Silverado 4x4. I got it complete with harness and computer minus the starter for 500 bux. It has 130,000 miles on it. The guy I bought it from was financially strapped and I pounced on the situation. I will be doing my own wiring with help from lt1swap.com and will do my best to detail as much as possible. Wish me luck.
