Hahaha...

I think the 444 engine is a bit lightweight for a bus unless the thing is driven carefully.
As far as all diesel v8 engines, the main reason i bought this skoolie instead of another coach, was for the turbo 3208 Cat v-8. And the fact that it is a THOMAS body, and not some

Just having fun all ya v-10 lovers.
BTW . have 92 ford pu for sale or parts...

If ya want a junk engine.. the one in my 1 ton 4x4 chevy is a 6.5 chevy turbo diesel... they are real junk...
Guess I shouldn't mention the fleet of beer haulers A-B used, then? 52,000lb GVWR (12K front/40K tandems), 170HP T444E, MT643 transmissions, steel springs all around. Ran them about 250-300,000 brutel miles in and around Boston...retired most of them after 10+ years, still have a couple as spares. Drivers hate them...steel springs, no A/C, and some have no radios...but out of 25, only two have had engines replaced.

And I was there towing them and doing road service when they were DT's and 3208s, many moons ago. Not many engine problems. Then again, if you were just banging them around the city is one thing. You surely wouldnt want to get on the outskirts of 128 and drive them much. Driving those rigs from Boston to Syracuse everyday would be a total different story.

They saw plenty of highway time...A-B runs out of Medford as far out as Newburyport, Quincy, Framingham, and even Fitchburg! Many of their routes are 150+ mile days.

Re: DT444 or Cummins 8.3?

Having crunched truck and construction fleet data for a living for 15+ years, I must say I find it funny that people have this misconception about the powerstroke/navistar V8.
VERY few of them blew up in fleet service. (In the five fleets using this engine I have done data for, the oldest in the fleet were seeing 250,000 miles in 24 foot trucks.)
Actually, there were a lot more problems with the B series Cummins when they made those 53 blocks (I think it was the 53 block anyway).

Though I would prefer the 8.3 myself, if I were looking at a 190,000 mile 8.3 that was a bit beat...versus...a 120,000 mile navistar V8 that was clean, the V8 would not bother me.

Few of the buses I've seen, that end life as a camper, clock more than 25,000 miles on the road before being so old they become hunting cabins or scrap metal.

We viewed a group of DT466 flatnoses with stickshifts and split rears from the midwest recently. Those would have been my best drivetrain if every one of them had not already been run to the 300,000 mark.

Re: DT444 or Cummins 8.3?

I have a t444e (199 runs great, no problems with it 200000kms on it real happy. One good thing is if you do need any parts or service you can get them just about anywhere, even a ford dealer if you dare. they are also somewhat easy to work on(I think),(I do my own work) there are lots of 444s \ 7.3 around there must be something good about them

just my 2 cents

Re: DT444 or Cummins 8.3?

what would be the rough mpg difference between the dt444 and the 8.3? especially in a mid to smaller size bus? or more likely the dt444 vs a 24v cummins 5.9 in a mid size bus (say 30 feet or less). that is what i am intently looking for right now.

Re: DT444 or Cummins 8.3?

I can't comment on the mpg of a 444 vs cummins 5.9, but if I didn't have my 466, I'd like the 8.3 Cummins.
