RSR, I hear yah. It seems that with 33's (which is the size I'll be using so I don't have to do any suspension lifts) the 4.88 gears are recommended, as well as the 5.29. With 33's the 4.88 is about 100 rpm above stock configuration, and 5.29 a bit more. These numbers are according to the online calculators. So, with the setup I want I'll be revving a bit more, with that logic the oil circulations should be fine.

This brought me to another question. I'm surprised to be reading an array of answers on this forum and other to the question "at what rpm is the engine at in 4th gear Auto OD at 70 mph. My car gives me exactly 2500 rpm. The online calculator says it should be giving me 2350 rpm. So with 5.29 and 33's it calculates 2640 rpm. If I extrude the same difference, my tach will show 2800 rpm. Everyone says 3000 is normal for these cars, but it seems a bit high to me.

Another late night long thought.

 

Keep in mind that 33 inch tires don't actually have a rolling radius of 16.5 inches (half of 33). It's more like 16 brand new, and 15.75 once they get worn some. Tire manufacturers tend to "inflate" (bad pun, I know) the size of their tires a bit.
Best way to figure the actual rolling radius is to measure from the ground to the middle of the hub when on a hard surface at normal inflation.

 

You bet, locker in the rear. Power and milage is back to if not better than stock, 4.88 is perfect for 33s, even with my 750lb quad in the back.

 

And I used a company in BC that gets all their stuff from marlin crawler, brand new drop I units.
