(96.85.4.38)		expensive....expensive...……..and heavier on the back end...…
we used a 1989 12 V Cummins & 2008 6 Speed Allison.

We went with the 6 speed to avoid changing anything on the rear
end...…
it took us a whole year to complete the task, do to funding problems.

(98.174.214.34)		Are you comfortable with extensive wiring mods or just mechanical and metal fabrication?

(154.20.196.160)		Duramax/Ally vs. Cummins 12 valve/built 47RH?

I'd be only guessing: 10-12/K vs 5-7/K.

(166.137.240.16)		You can also find Cummins Allison combinations in step vans and some other pusher motorhomes so don't limit yourself to pickup donors . There are also duramax 4l85e combos from express/savanna vans

(71.92.153.147)		Have you read thins thread? http://fmcowners.com/mbbs22/forums/thread-view.asp?tid=295&start=1 and the associated photo album?

Also this thread and the associated photo album? http://fmcowners.com/mbbs22/forums/thread-view.asp?tid=683&posts=18...

When I was at the considering/evaluation stage, there were two main factors that pushed me into using the Duramax. One is the lighter weight of the engine and the second was the the much broader torque band. In practice, that wide torque band has been wonderful to work with for the last 44,000 miles or so. The Duramax torque band is from 1600 to 3200 rpm. Compare that to any other diesel you are considering.

Remember, once you start the project you have finish it!! There will be many things to figure out as Len and I and Rico and others found out. Read the above threads and the compete photo albums to see what all can be involved. The mechanical engines have a little less, but still lots of things to consider.

There are lots of "good" diesel engines out there. The question is "which one is best for the FMC?".

(172.10.134.245)		I'd look for a cleaner (less rust) one, but this configuration would work well and already has the heavy duty parking brake installation.
