How not to install a Duramax in a M998

[Mogman]

I have a duramax/allison 5 speed in my Civillain Hummer, it has 2.56 gear and max speed is 87 mph then its governed by the ECM, We had one in a race Hummer also and it would only do 91 in baja. You conversion looks great.

If I remove the speed limiter but leave the stock rev limiter in place it will do a little over 120MPH.
Almost 17K on the conversion and have not had to rework anything I can think of, I have blown out a bunch of aftermarket half shaft boots but what can you expect from cheap Chicom stuff.
