Check out the isahara-johnson windage tray mods, I kinda like their mini rear tray big block idea too, keep the oil where it is needed. I put one of their scrapers on my sons bmw when he was scca class racing and we never had to freshen the motor again. At the time his class required stock pan and no accusump. If you ever build a bigblock car for cornering get rid of the windage tray, or add a ton of holes to the side by the block, or use a crank scraper, or use an accusump, unless you like blowing motors. The stock trays seem to trap a lot of oil, and stops nothing from going up the rear on acceleration. I am thinking the trays with screen and a scraper would be best on a street car, for best control of windage, vs returning oil to the sump. I would suggest measuring your pan with tray in it to determine oil level, make sure it is below the tray.
