Oh, yes, that probably didn’t make any sense. The guy told me it was a 2001 5.3 non-flex, and 5.3 flex didn’t come out till 2002-2003 (depending on where you look), which made it confusing on what it actually was, and with a “4.8” stamped on the head gasket tab made me think twice (or three times...)
Overall I now am confident it is a 2002 flex 5.3 - injectors, crank/piston/rod casting, and non-DBW throttle body all say 5.3.
