crank doesnt touch the oil in the pan, Look how deep the full line is on the stick when its inserted with no pan. Thats your level when its NOT running. figure about 2 inches of that is going to be upstairs when the car is running. The scraper is overkill, it peels the oil off the crank that naturally clings to it so your sort of adding drag to the motor by constantly scraping this oil off. A windage tray flings the oil off naturally and just routes it away from the crank so it doesnt grab it again in its natural vortex. Ishihara/Johnson sells crank scrapers so they are going to spout its virtues, but do you wind your small block past 7000 RPM for extended amounts of time? If so, go for it. They say a scraper AND a windage tray form a system to keep oil from aerating and flowing to bearings in that semi solid state.
