meltdown.

 

Mine holds a little over 6, but I use a longer filter, about the length of the old PF-59.

I'm not sure how much volume my stock pump puts out, but oil pressure has never been a problem for me, not sure what the factory gauge numbers figure out to in reality, but my gauge always pegs at WOT, and is over 40 psi at idle with either Mobil1 or Amsoil 5w-30. Too much pressure can blow seals out and may cause blowby into the combustion chambers...although I'd think/assume/hope that a GM factory part wouldn't have that problem, especially since it's a production part.

If you're only a quart over-filled you should be OK, but too much oil can definitely cause problems. The oil can foam and lose it's ability to lubricate, as well as find it's way into the intake through the PCV system, which is already a problem with the GENIII engines with the oil at the correct level.

Hope the new oil pump works out for you Jermoslin, good luck with your set up

 

If you have had your oil pan off before You will see the full mark on the dipstick is about 1" below the windish tray. Seven quarts don't even fill the pan up completely. the pump I used it for the NNBS with displacement on demand. Yes, LS1, LS6, 4.8, 5.3, 6.0 are the same pumps and you can only buy an LS2 chains all new GM LS motors chains use the new bigger chain.

 

"windage" tray

...the oil pan isn't supposed to be completely filled btw...

 

The dipstick isn't an accurate measurment. GM says 6 quarts, so that's what it is. But what would they know.
