The oil starvation issue does not cause a momentary stall. You need to look elsewhere, perhaps at the fuel pump, or perhaps if the turn is tight enough and the ruel tank is low enough it may be a normal situation.
The oil starvation issue means that you can loose oil pressure (or better said, no oil is getting picked up from the pan for the oil pump). The biggest issue is that there is not adequate oil drain back from the heads so that at sustained high rpm there is very little oil in the pan. Combine that with a sweeping right hand turn and what oil there is in the pan is no longer under the pick up pipe.
If you loose oil circulation at high rpm, there is a very high likelyhood that you will wipe out a rod bearing.
It helps to avoid driving hard on sweeping right hand turns. It also helps to slightly overfill the oil. I use 6 quarts instead of 5.8, and many here will use up to 6.5 quarts.
Some have installed a Moroso oil accumulator that will provide additional oil under pressure for a short time when the oil pressure drops.
Some have done the 3.0 liter conversion with the 3.0 heads that have better drainback.
