Ok.. I have been told 6, 8 and 9 quarts ..what do you run in yours????? my 1967 Luhrs has LM318 RH engine with a huge looking oil pan that is cast aluminum .... It has a baffel in it and its almost impossible to get all the oil out of it.. Just how much oil is it suppose to hold anyway...The book says 6quarts but looking at it that can't be right...looks way too big to only hold 6 quarts.. . I have found several of them for sale but none of them tell the how much oil they are suppose to hold. I really need the correct information so I can mark the dipstick when I get it back together... thanks in advance..
