What's the part no. for the LS4 oil pump and the LS2 timing chain? How do you know it flows more- is it higher pressure or higher volume?

Will the oil pump fit on the LS1/LS2 block without modification?

Where was a LS4 pump tested to flow more than a stock LS1/LS6 pump?

The car has more pressure everywhere... this will be esp. good for me w/ my oil cooler and running higher oil temps at HPDEs. The higher volume pump will keep pressure up even as the oil heats up and thins out.

Thats correct. $139.94 and never failed in all C5-R racing and durability testing.

Can anyone confirm that the LS4 pump will fit an LS1 without requiring any modifications?

I know everyone wants a "bigger" (higher pressure and/or volume) oil pump, but is there any evidence that is necessary? Are LSx engines prone to bearing or other failures due to inadequate oil supply?
