Keep us posted on this transplant please.fastvicar said:Just got ourselves a super-clean '72 F250 Camper Special that we'll repower with a 4BTA & 5-speed.
We must have a good one. 7.3, one of the last years for it at 2001 model, mated to the automatic. Gets 17mpg all day long, no matter what task you've set before her. Towing, hills, empty, city, highway, fully loaded, bobcat hauling... always the same, 16-17mpg.Oil_Burner said:I'll believe 22mpg out of a Struggle Stroke when I see it. Nobody I know gets better than 14mpg. And I know a few dozen Phord drivers.

It very well could be off a display. They also never give an exact number so who knows.![]()
Yeah I had hoped for a little more with the Sprinter but I replaced an '88 step van with a 6.2 that was getting 9-10 mpg.
A local carpenter with a lwo roof model in my area says he gets close to 30 with his. I'm not sure what exactly "close to" means though.
Thanks, that made me laugh pretty hard.Bob S. said:The Ford Super Dutys have the areo dymanics of a cinder block with Dumbo elephant ear mirrors sticking out to the side.
That was very interesting Rob, thanks for the tidbit. So you're saying that this configuration could fit into a 1971 GMC too? Possibly?UnclesCamino said:The old chevy p30 delivery vans had a 3.9L Cummins b4t. Its the 5.9 engine with 2 less cylinders. The motor is a direct bolt in into a 70's to 80's chevy half ton with the van motor mounts. They are about 110 hp and move the little half tons around pretty well with the right gearing some guys are getting 37mpg with them.
Rob
Yes should fit into that with out any problem. You might have to fab some motor mounts, I am not sure if they have the same frame design as the later 70's early 80's mounts. If you get the cummins out of one of the Chevy delivery van it will either come with a Turbo 400 auto or a muncie 4 speed with a chevy bellhousing. The engine and transmissions are on Ebay alot for about $1500-2000 with about 100,000 miles.

But what is the point to drive a dually like a granny and not towing anything ?2171Jetta said:. It could be possible to slip into the 30s if you drove like a granny and were using propane.
actually, i knew a guy back in savannah that had an '04 F250 that used a lot of propane. his diesel consumption was has high as 36-38mpg, because he is offsetting the diesel with propane. after he calculated the cost of propane and usage and comparing to the [at the time] price of diesel, he actually came out w/ a comparative cost of 26-27 mpg of diesel.2171Jetta said:...

not arguing, just sharing what i've seen w/ adding propane. you gain a little bit after a lot of work. in my mind, i'm not sure if it's worth it.2171Jetta said:There is no point to drive a dually if your not towing anything. I was trying to point out the absurdity of getting that kind of mileage with a Powerstroke dually.
