Picked up an engine yesterday from local salvage yard for $425. It came out of a wrecked 2003 Silverado. But it was an engine swap for factory 6 cylinder. Therefor, mileage unknown. I used my boroscope to look down oil fill tube and super clean. Then pulled plug to look in cylinder, again super clean and confirmed dished pistons making it a 5.3L. Rear main seal is bone dry. 706 heads. Will check casting marks to zero in on manufacture date.

Got it home yesterday, will clean it up this weekend and drop it in next weekend.
