Of interest. Not Pontiac specific but here they mention cavitation....

"While most applications – whether stock or performance – use a wet sump system, it should be noted that they have some rpm limitations. There is a physical limit related to rpm on a wet sump, where once that threshold has been crossed, the gears or rotor sets can no longer continue filling with oil, and cavitation will begin. This happens typically somewhere between 6,500 and 7,500 rpm, but may occur at lower or higher rpm levels."

Mark at Luhn used a pick up tube simlar to this:

Oil Pump Pick up tube (15/16) for Ford Modular Engine 4.6 / 5.4

The early Luhn design pick-up was based on the oil pump study by Ford and Aston Martin and had a proper oil inlet tube diameter for high performance use at high rpm.
It was similar to the Ford Mustang Cobra Pickup

As Dragcar did, we bought one similar in the Ford system for our own use and cut it to length.
