Junkyard LS

The 5.3 and the 4.8 look the same from the outside. It the motors are in the truck you can check the Vin for the motor displacement. Otherwise you have to look at the top of the pistons. The 5.3L's have a dished piston, 4.8's are flat. That way GM could use the same cc heads on both motors. The 6.0L is cast into the block. Watch for Escalades and the like for the big motors. Also more likely to have DOD installed. This can be deleted. If the motor has a drive by cable it is likely from the early 1999 and the early 2000. More likely to have high mileage. Learn the what the different generation ECM's look like. This will get you to the General year and motor series.
Happy hunting.

The engines listed for sale are removed already, so I would have to find pedal linkage and such separately.

I'll just share the auction link, below, if anyone is interested. Hopefully I don't end up bidding against a member.

Given the info provided maybe someone could tell me which one they would buy if they had the chance. Lots of transmissions and diffs, too, of course.
