Crank scrapers or plate...?

Do a search on engine masters challenge an see what the guys did , a few years ago full lenghth tub style pans were allowed with a good kickout on one side , that is what seemed to work best!The deeper your pan the further away the oil is the better , screen and louvered trays both work adjusting your distance can make a difference , crank scrapers have worked and in some cases have had a negtive impact on output , only dyno r&d will tell for your combo , directing the oil away from the cam valley , channeling it back to the bottom of the pan and away from the crank works good too.Concetrating on having constant reliable oil supply at the sump should be #1 priority , baffles around pick up , and make sure you dont have too much oil , somtimes those dip sticks are highly innacurate or mismatched .
