Whatever trans you are using, you can use it over-like the Allison HT740?  Just need to change the throttle position senser out to an electronic one.  But-if you're changing from a 8V-71 or 6V-92, you should either change the rear end ratio out, or the easiest would be to use an Allison World transmission with the two overdrives of .74 and .64.  Running a M11 at 1800-2000rpm is alright, but for best fuel mileage, it should be cruised at 1500-1700rpm.  Good Luck, TomC

Lot of Eagles with the M 11 check these guys they know all the scope www.eaglesinternational.net (http://www.eaglesinternational.net) easiest engine to install in a Eagle,most of the guys use a 740 Allison with 3:36 rear gears only one has the world and he just uses 5 speeds

Yep some Eagles came from the factory with a 748 and M 11 with no drop box just a flipped truck rear end with 3:10 gears but not with the retarder transmission probably will work since the 748 is not that long to start with


good luck

So do I still keep the drop box and think I have a 373 rear end will
this motor and trans and gearing work together?

All the M11's I've seen were 12 volt.
