Oil change and other changes

My whole point was that because a vessel's capacity may be X, does not mean it's best for the engine (which is dynamically in many different positions other than flat and level) to run at that capacity.

I know by measurement that my 8 qt Canton runs best at 7 (in the pan, static) with nearly an inch gap to the tray. With 1.75 qt in rest of the system, the sump does not pump itself dry. Pat, speaking for myself, my Shelby heads and the block's valley do NOT hold a ton of oil. Attention to the oil drains on assembly assured that.

Ray runs a 460, 385 with at least an 8 or 9 qt capacity pan with no ill effect with 7 in the pan and at least 4 in the whole system.

There's just no need to run so much excess oil IN THE PAN. And since you asked the question and described your situation, Pat, Doug, John, Fred, Ray and myself have told you that there's a better, safer way.

Your engine has no greater oil requirement than a rebuilt 390-Joe builds 70% of his ERA-based FE's that way.
