Keytag1 No the original owner did the build at around 20,000 miles on the truck. Second time he blew the engine. Chevy black listed the truck so his warrant was gone. He forgot to unhook the big tune on it. Thinking he had around 500HP out of the Duramax both time it ate a piston.
They were pulling a 45ft inclosed trailer full of Custom motorcycles around the country with it. Over grossed and high HP got the best of it for him.
So he bought a 10,000 mile 2000 5.9 275HP engine out of a Diesel pusher. IT had burned from the Fridge. So engine sat for a few years. Then he took around 1 year getting the build done. Destroke build the trans box for him. That from what I found out was the first one they did for the 5.9/Allison for the chevy. Hundreds of hours later and 3 days of someone from cummins main office at the shop. They got it to run right. Pulls great and not bad on Fuel when I drive it right. If I keep it around 65 it will get 12 MPG. IF I run it had 8 MPG. Grossing most times close to 30,000 lbs. 6th gear 0.61 ratio, rearend ratio of 5.13 and 19.5 tires lets it run 70 MPH at 2150.
Also have all the paper work on what work they did parts for the build.
If I don't get the engine and trans to work out. And don't sell it and buy a Semi to pull our camper. I'm thinking a newer 6.7 cummins and trans out of a Ram may find its way into it. That or a M11 cummins.
