Any Cummins Truckers
My old '02 Shaker had a 60 series 12.7, 13, and 3.70 rears would average out around 6.3 some times a little better. That thing was unbelieveable, ohio, and illinois speed killed my mileage. That truck LOVED Arizona, New Mexico 2 AM speeds.
I have driven a couple detriots sence and couldnt average over 4.7, they pulled OK. But nothing like every Cummins I have driven. Had a C-15 Cat twin turbo in my company Werner trucks and a log truck that wernt too bad, but either detuned or just the wrong transmission. Anything under a 13 should be banned.

, I hooked up with 4 other Rooster Cruizers pullin outta the El Paso Petro at around ............ 11 PM or so, needless to say I was in Barstow Cali by 10AM. Loaded, and averaged 6.5 MPG too.
Damn I miss that truck! Ohio and Ill. cut me down to 5 religiously (IF, I ran the speed limit.)
Hehehehe Sorry officer I wasent paying attention....... 76?!?!?! oopppss
Got a seatbelt ticket outta that one in Ohio, nice guy i might add.

I'm looking into buying a 85 W900B w/ a big cam IV 400 hp engine. I've posted else where about it. It's black smoking. Had a sudden loss of power. Oil smells of fuel. Thinking turbo. Gonna buy it and see about putting some power to it if I can just find out how to. Let alone make time to go get it and figure out what is going on with it.
you can get some pretty impressive power out of the big cam engines, hang a good turbo and turn the fuel up a bit and it will be pleasant. If it started black smoking all at once it prolly is the turbo or an intake hose
I have an 81 Peterbilt with a big cam 400. I have had several trucks and tractors with Cummins', but this one seems a little doggy.

2007 Pete Short nose with Cummins ISX set at 475hp. Love my Cummins! Almost wish I hadn't stopped driving, but honestly I like being home!
Also have driven the 670 Volvo's with the ISX, loved both trucks! I know, I know, Volvo is for whimps, but I didn't start having hearing problems until I drove a Pete around for a year!

My 1981 359 Peterbilt that I restored last winter.
Big Cam 400 Cummins
13 spd
Wheelbase was shortened from 237" to 208".
Motor was overhauled before I bought the truck, but it is not as powerful as other Cummins' I have driven. Any advice on what to do about that would be appreciated.
