5.3 piston question please help!

Those are floating pin rods with the flat tops..... So unless they are from a late 4.8 ( which the rod is a different length) those are L33 rods and pistons shown above.
4.8 has a 6.4" long rod as compared to the 5.3/6.0/6.2 length of 6.125"

L33 is the RPO code for the engine ( like LM7, LM4, LR4, whatever) and designates something specific, not a generalization. So yes, an L33 is a flat top piston equipped 243/799 headed 5.3.
