You could have one of four 5.3 engines....LMG,LC9,LY5,or LH6.

Look at the eigth digit of your VIN...

0 is LMG

3 is LC9

J is LY5

M is LH6

I guess what I'm getting at is what valvetrain do our engines use? LS1 cams, etc...

  Good to hear you got it figured out. Did you grease the upper ball joints before you put the caps on? I don’t believe mine were greased from the factory so I greased them when I installed them.

  In the top photo, option E ( the bottom dipstick ), I always find very satisfying for some reason after I've run the engine to fill the filter and after a period of time check the level and see that hard to see translucent oil at the area of the full mark ( and typically check the next morning to confirm the exact settled level ).

  The 6L90 in the 2020+ trucks has several improvements over the 6L90 in other trucks, so the comments made about issues with previous versions may not apply. I have been totally happy with the 6L90 in my 2021 3500 HD. The L8T has plenty of torque over a wide speed range and does not need to be held in a narrow rpm range unless you are towing near the maximum weight. Even then, six gears works just fine. Personally I don’t like what i consider the excessive shifting of most ten speeds, but i have not towed with one of these trucks with a ten speed. If you are buying used I would prioritize condition, miles, maintenance records, absence of stupid unreversible modifications, and towing history as more important than ten speed versus six speed. Make sure you try the seats out before choosing a trim level. I can drive my SLT with the leather bucket seat (premium pkg) option for 8 hours and get out feeling fine. I was uncomfortable in the SLE cloth seats with fold down center seat by the end of a 20 minute test drive. My wife loves the SLT leather bucket seats, too.
