Oil flow path?
What is the path the oil flows in a LS2?
is it - oil pan - pickup - filter - pump - bearings - pan - cam - pan - rockers - pan
Dose the pump supply everything at once or is there a priority like main bearings, then rockers, finally cam?
Are there diagrams for this anywhere?
Pictures work better for me.

I found it
The stock GM Gen III/IV oiling system routing goes like this:
Oil pan – pickup tube – crank driven gerotor pump – main oil galley (driver’s side of block) – oil filter – up rear driver’s side of block – main feed galley (runs through the lifter bodies) – up to top of engine through pushrod passages – drains back to pan through drain-back passages throughout the heads and block – oil pan.

WOW I just read the article on that page, what a great write up!

Since the LS engines drive the oil pump at crankshaft speed rather than the former camshaft-driven pumps, is the oil flow twice the volume at any given RPM as compared to the older systems at the same RPM?

I wouldn't think so. Designers sized the oil pump flow for the engine requirements.
