Mike I am running the z5 in my wc 3 6x6 which weighs in at 6600 lbs. I have sta 900x16 and the 4bt is orginally 105 but with the intercooler a I think it is about 120 to 130 hp.The rear end ratio is 4.89
60 mph is 1900 to 2000 and at 2300 it runs out at 75.I kept the tire size smaller than your 40 inches due to the fact the engine is more responsive with less unsprung weight and I didn't want to feel like I was driving the old 84 hp flathead.
1st thru 3rd you have about a 500 to 600 rpm power curve and when you get to 4th and 5th it has a larger power curve.
The truck has consistently run at 25 to 27 mpg at 60 and I am really happy to have a nice road /off road truck that I can afford to drive.
