You should have at least 20 lbs. of oil pressure when hot at idle, and 10 lbs. per 1000 rpm when cruising.
You will probably experience a slight pull and/or tilt to one side.
The oil pressure reading for a Humvee at normal cruising speed typically falls within the range of 15 to 40 psi. It's important to monitor this gauge, as consistently low readings may indicate potential engine issues. Ideally, the oil pressure should stabilize around 20 to 30 psi during regular operation. Always consult the specific vehicle manual for precise specifications.
If everything is working properly, the oil pressure will be controlled by a "bypass" valve inside the engine. Once the oil pump builds enough pressure, any additional volume is "dumped" back into the crankcase so that the oil lines don't build up too much pressure and damage the bearings and oil pump.When the engine is cold, you should see the MAXIMUM oil pressure. Start the engine, watch the oil pressure and see where it goes. The needle will rise rapidly until the bypass valve starts dumping excess oil. Wherever the needle stops, that's your normal oil pressure. Usually it's somewhere in the middle of the gauge, 40 to 60 psi, but the exact number isn't critical. What's important is keeping it in that range... wherever the bypass takes over. If the engine warms up and the oil pressure starts to go down, you have worn bearings. That's the most common reason for a loss of oil pressure in the 350 engine. It's a great old engine, as tough as they get. If the oil pressure is starting to go down when the engine is warm, just change to a heavier grade oil at your next oil change. If you've been using 5W15, change to 10W30 or even heavier. That will help you get a lot more life out of the engine. The thicker oil will keep the worn bearings lubricated better and help the engine last longer.

A 1996 Toyota Tercel will hesitate on acceleration at cruising speed if the fuel filter or injectors are clogged. This prevents the engine from receiving enough full and will hesitate.
plug wire ... there's one that gets too hot and deteriorates
Yes, i have a 1961 Ford F100 with a 460! Love cruising!
Around 20 psi at warm idle, about 40 - 50 at speed. Should be the same for both the M998 series with the 6.2 naturally aspirated engine and the M1113 series with the 6.5 turbodiesel.
The fuel pressure regulator maintains a constant predetermined fuel pressure regardless of engine RPMs.
Pressure of WHAT .
The pressure ratio in jet engines is the ratio of pressure between the entrance of the compressor and the exit of the compressor.
