oil pan

Small Block said
Now lets just think about this and give me some good answers. When the pan is on and all the specified amount of oil is in the motor on any motor whether it be a slant six or a 440 or a 426 hemi. What would be the oil level in the pan in comparison to the bottom of the lobes on the crank.

Depends ont eh engine. In small blocks, about 3", on a big block, slightly more.

The crank doesn't run in the oil so how far below the crank is the oil level not running. Does it vary from one motor to the next?

Yes, there is about 2qts in the sump in a factory 5qt system, the rest is being pumped thru or in process of draining back to the sump when it's running. This varies engine to engine.

I guess one could fill a stock motor with oil and drop the pan and see how far down in the pan the oil level is and then see how far the crank lobes set below where the pan flange bolts up to. Anyone ever heard of a crank scaper?

Crank scrapers are the best way to control oil. The majority of oil drains back past the cam, fallign on the crank, and getting caught up around it. The scraper removes this parasitic power robber and directs it to the sump much faster. In a modern engine, oil control, rather than volume or weight, is MUCH more critical. You want to pump just enough to keep it together and keep things cool, with the least amount of power robbed or heat created, and it needs to drain back without getting caught by the crank.
A modern Stock Eliminator will reduce the oil in the system to less than 3qts to back up a record. Some run that level all the time. It makes that much of a difference.
