Crank scrapers or plate...?
one benefit to windage trays and scrapers no body brought up yet,..all of us spend untold money to balance crank rods pistons ect ect,..if ya don't control the oil in the pan and crank covered with all this oil spinning high rpm's thats added weight that's gonna effect your balanced bottom end,..the harder you spin it the worse the effects gonna be...some folks build the cheapest thay can some build the most hp thay can,..if a few hp and a better oil system that allows your crank a happier life worth the coin do it!!
