360 oil psi dropped all the sudden

Agree with Mopekid3. Never use a non baffled pan in a car that you race (even street hot dogging). A windage tray isn't any thing like an acceleration baffle. A pan baffle keeps the oil in place (where the oil pump pickup can suck it up) under hard acceleration. I made the mistake yrs. ago of using a stock pan on a 360 and with stock radials had no problem but as soon as I put sticky tires on it the oil pressure would go way down on takeoff and naturally the bearings didn't last long. As for sucking the pan dry, that's an old wives tale that a lot of us used to believe until we ran across an article the Ramchargers produced way back in the 70's that proved the oil pickup is too restrictive to allow that to happen. In fact it showed the flow results of a stock vs. hv oil pump with a stock pickup and the hv pump didn't hardly pump any more cause the stock pickup is too restrictive.
