Thats what i was thinking when i was going through the manual, it was just a little all over the place i guess is how you would say it. Or at least it was to me... is that for the main bearings and the rod bearings?

Yes and generally speaking if you are on the loose side you want to run a high volume oil pump. If it's tight, run a standard volume.
