Hey guys I need some research help. I'm researching a future project with a M814. I'm building my project truck to be an RV (crew cab with sleeper) and tow my 35' cruiser boat on a gn trailer.
I know the M814's come with the NTC 250 Cummins... UGH... I am going to need a bit more power than that engine is willing to give me. I'm researching a repower with another Cummins. My options right now are a Big Cam 290/300/350/400, an M11 or N14. For towing the boat and backing down ramps, I'm looking to mate an Allison to which ever engine I choose. I'm not looking for major speed, but 60-65 max towing would be nice.
How many of you have repowered with one of those engines? What Allison trans would you guys recommend? I have a few in mind, depending on the engine I choose, and it doesn't matter if it's a 4 or 5 speed.
For those who have repowered with a higher hp engine, have you changed or upgraded your t case? That's my only big concern that the t case won't handle the higher torque numbers.
Any and all opinions are welcomed.
