Oil Pressure goes to 0 off of a hard launch

As aid, pan to pickup clearance should be no more than 1/4". I aim for 1/8, and it should have an acceleration baffle. The windage tray would help once things are moving...But the pickup is being uncovered at launch. If this has shown as 0 on the gage for more than 5 seconds more than once, I would tear it down and inspect the bearings. It's easier to do that while the pan's off for the clearance check...
