My buddy has a 4106 with 8V71. His oil pressure is about 10 at idle and 40 running down the road. Is that right? My 6V92 makes quite a bit more oil pressure.

The other difference we were pondering is why my 6V92 stops in about a second while shutting down and his 8V71 runs down to stopped in about 5 seconds. Is that normal?

oil presure is OK, shutdown time OK

I have a 8V71 in my Eagle. Idel is between 5-10 psi. Running down the road 1900-2000 rpm, it's between 30-40 psi.

Let's talk about climbing hills. That will break your heart.

the great racing pundit & engine builder, Smokey Yunick always stated that a good rule of thumb on oil pressure is at least 10 pounds per 1000 RPM. Old Jimmys fall right into this. i.e: 500 RPM = 5+ PSI,
2000 RPM 20+ PSI etc.

Da Book says 1200 RPM Normal 40-55, minimum for safe operation 25. 1800 RPM 50-70, Safe operations minimum 28. 2100 RPM 50-70, minimum safe operation 30.

It's not unusual to find a difference in the reading on the electric gauge on the dash compared to the mechancial gauge that is usually in the engine compartment. The mechanical gauge may read significantly higher. I would tend to rely on it as being more correct and then use this as reference. If the numbers from the mechanical gauge are within acceptable range, whatever is shown on the electric gauge for the same temperature and rpm should be okay.
