5.3 truck oil pump vs LS6 From what I have read here is that the 2001+ LS1 oil pumps are the same as the LS6 oil pumps. Does that hold true for truck motors as well? I have a 2002 5.3 and was wondering if I should swap the oil pump or just leave it alone while I have the front cover off for a timing chain and cam swap.
Future mods include a front mount single turbo, but the car will be NA for a while with just an LS6 cam and upgraded springs/pushrods.

They're the same. The pump that came off my 03 LQ9 is the same part number as the LS6 pump. Furthermore, I bought a brand new LS6 pump, and now they're made in Mexico and the inside looked like it was machined with a jackknife. I wound up porting and re-installing a used pump instead of the new one.
