That truck is AwESOME! And mean too! That’s a lot of engine for that long ago. Did you build the engine?
It wasn't really that long ago. I bought the truck in late 09 out in Phoenix. Motor was done by a friend who was an engine builder, he'd built NASCAR and off shore racing boat motors. He'd even work with Smokey Yunick on a Indy 500 project. The motor was built for low end grunt. I pulled one year with 4.56 gears and the next year bought a bigger trailer and changed to 3.73 gear. That was a big mistake as the mileage went down the tubes. Pulled through Mt. Id. Wy and the mileage dropped into the 5's. The problem with the 3.73 gear was that I was unable to run OD many times while with the 4.56 I'd have been able too and at lower RPMs I bought my 07 diesel that fall and more than doubled the mileage.
Here's my 07
