The C7 is a baby Diesel. Used to be known as the 3126. 7.2 liter. RV trim for 2004 was 350hp @ 2400 rpm 860 ft lbs @ 1400 rpm. This was Cats smallest on road engine and the only one with parent bore block. Everything else has sleeves and can be overhauled in frame.
Dennis,
From my phone.

I guess I was in "Vanagon" mode :-) I designed Railroad track renewal machinery for about 40 years so I am familiar with large engines and oil capacities but somehow I didn't switch modes. Steve
