Re: DTA360 questions...
I drove many thousands of miles in a bus with a dt360, including a few trips from michigan to nevada and back. (about 5K miles each trip) One trip i pulled a trailer and was loaded about 6K pounds over the gvw. I drove her full throttle for about 110 hours roundtrip. She just kept pulling like a freight train. I had about 200K miles on it when i sold it and still running strong.
I had poor highway gears in the bus. I got about 7-9 mpg at a bit over 60 mph.
The final trip i made to nevada and back i had "turned up" the hp and the speed. I found that if i continued to drive just over 60 mph, i actually got better fuel economy, and i could accelerate and pull the long hills faster.
I definitely recommend turning up the hp and the rpm's. simple, free, and relatively safe. putting in an exhaust gas temp gauge would make it 100% safe.
I think the 360 is the same block as the 466, just different cylinders.
Fuel economy is not that great. My buddy with a 5.9 cummins motor (and better highway gears, and better trans) got about 50% better fuel economy than i did on our trip to texas and back in his blue bird tc2K.
the dt motor was a good cold starter. I could outstart phil's 5.9 cummins when it got below freezing.
the 5.9 cummins is my favorite skoolie motor because of it's fuel efficiency.

They're known for dependability and fuel economy....I don't want to jeopardize either for a few more MPH. I'm sure others will feel differently however.
