I am looking at a cheap MC7 with a bad engine, and a very good body. I want to use a Turbo V8 Cat, 3408 750HP engine, and a 10spd. I would like to get good fuel milage, so i want to run the engine in the power range of 1200. What is the std rear axle ratio of this bus? Thanks in advanced for the help. JB
Dont know the std ratio but the 4 strokes are much lower RPM than the DD 1200 to 2300 {for a while} power band .
Youe gona need a new axle ratio whatever you do.
Why not find out what MCI does with the new stuff and copy the factory set up??
A 750 hp engine {if it will run for over an hour} will be using about 35 gallons of fuel an hour , This is economy???

But just think FF, with 750 H.P. he will be able to go over every hill in high gear.

The standard axle ratio is the 3.73 Rockwell, I have uses the origional 8V-71 with the Eaton Roadranger 10 speed, then installed the 12V-71 with same transmission, still using the 3.7 rear. Then I installed a 8V-92 and changed the 10 speed into a overdrive, this gave two things,
1-Lowered rpm to about 1550 @ 70 mph.
2-Gave top speed way up in the stupid number area.
Still use it and love it, I am now ready for a auto and a 3.33 rear.
Good luck
