Cummins Deisel Engines

I have 3, Cummins Series AT, 6 cyl, engines all for one price of $1500.00. These are a smaller engine than the B series in the Dodge Pick up. These engines were made in the early 90's, they have manual fuel rotary fuel pump. They are turbo charged. They are about 110 to 120 horse power. On the back is a GM style bolt pattern for a typical Chevy bell housing. They have flywheels, clutches, and bell housings. I only have one rebuilt started for the 3 engines. These are pull outs, I have never had any of these engines running, but I have others and they ran fine. Out of the 3 engines you should be able to make at least 1 good engine if not more. The outside dimensions are almost exactly the same as a Chevy 235 CID 6. 253-380-5517

Never heard of these. Interesting...did he say what they are out of?
 
Very interesting indeed... I'd like to see the torque curve on these. The fact that it's got a Chevy bellhousing pattern makes it especially cool. I bet it'd bolt in with nothing more than the right motor mounts.

:thinking:
 
So far I've found it is an "6AT" series 3.4L I6.

120 hp @ 3600 rpms and 210 ft-lbs torque
220 lbft @2000 RPM

Looks like it may have been designed to be a bolt-in, inplace of the 250 I6.
 
Notice the fuel filter...

Interesting... I wonder how much boost was used to get those numbers.

It's a bit low, but it would probably work in a full-time street K5 on stock tires (like I have :D). I wonder what the fuel economy would be like in that situation. :thinking:

Edit: I think it'd work ok since the 4.1L (250ci) inline-6 was offered in these trucks. The 194ci was the smaller end of that engine family, with the 250ci being the largest (the 292ci was a different block). 3.4L puts this at 207ci. Now granted, it's smaller, but it's a turbo diesel. I have to wonder how it'd respond to some mild hop-up tricks.
 
Wow, I didn't realize how close that was to fitting a Chevy. I've got a 4BT in the garage, but this sounds much easier to fit.:thinking:
 
This motor looks very promising to me too... just gotta graduate from college before I can move on with a big project :doah:
 
How's the parts availability?

Intriguing definitely.

If you buy three... you would have spare parts for a while. But other than that I don't know yet. You would have to call a cummins/onan dealer for parts I would guess.
 
were these used in vehicles, or in ground equipment(generators, etc.)? If they weren't used in a vehicle it will be a maor PITA to get the thing registered in some areas.

What I have found is both... I've never lived anywhere with an emission check so it wouldn't affect me. In many area's with emissions though, diesel would be exempt, but not all area's are like that. So it is definitely something to check first.
 
In that case, it looks rather promising. I would rather have that with a turbo than my 6.2, even if I had a turbo.
 
I'd think if it had a Chevy bellhousing pattern it must have been used in a vehicle at one point.
