A little advise John, on my 383 I'm running a high volume oil pump and was running a MP windage tray. At high acceleration from stop (foot in the carb) my oil pressure was dropping off 20psi at around 5000 rpm and I nailed it down to the MP windage tray not having enough slots to direct the oil into the pan and instead the oil was going out the back of the tray and starving the pump. This with a 6 quart pan with baffles. The problem went away with the installation of the Milodon windage tray, it has twice as many slots.
