any of you guys know anything about the 6at cummins? seems to be a baby brother to the 6bt (obviously, its one series down)

any chance one would be small enough to fit under a rangers hood?

 

I saw one post on another forum that it was the same dimensions as a chebby 235, so I dont see why not to try it in a Ranger. There's no aftermarket performance stuff for those, so you're on your own.

 

never heard of a 6at, see what inforormation I can find. Might be similar to a 6bt cummins which i am quite familar with. But, if I were you I would put a 4bt cummins in a ranger. You can find them in bread trucks and things like that. I've seen rangers with 4bt's in them. A 4bt has a lot of power. Its really similar to a 6bt minus two cylinders, and minus 2 liters in engine size. The 4bt is 3.9 liter, a a four cyliner where as the 6bt is 5.9 liter, and 6 cly. i'll show you a clip from youtube some time. Did you find a 6at?

 

The 6AT is a 3.4L (210 cubic in) producing 108 - 125 hp at 3,300-3,600 RPM. There is more information at Onan 6AT Conversion, How is it? - Pirate4x4.Com Bulletin Board.

 

Thats pretty cool. Sounds more like a 3.9 liter 4bt then a 6bt though..

 

Just think of a 250- 6 cyl out of a Maverick, it's about that size. Very good/ universal size.

 

I'm fixin to put one in my '59 f350 flareside. I'm supposed to pick up a sm 465 tomorrow. I've been running a 6 at in a 54 gmc with a th 400 auto. A friend did the swap about 8 years ago and I've had it for about a year. I don't like gm trucks much and I really don't like automatics, so once this is done, I'm gonna sell the gmc. These engines are really nice power plants.

 

Man that is sweet! I would love to see it with its own build thread!

in the meantime though, how does it do in the jimmy? does (did) it propel it decently enough? any mileage numbers?

 

I'm thinking of doing a build thread, but it will probably be in the 57-60 (fridge) section. I have posted quite a bit there aboiut the sterling 10 1/4 dually pickup axle and my adaptation of the front hub to 8 lug etc. As you can see, I picked up the 9' flareside box as a utility trailer and then had to find something to mount it on. Speedo doesn't work in the jimmy, but we clocked 63 mph between the mile markers while towing our '58 aloha 15' travel trailer. It seems pretty good on the mileage and it's only 210 cu in. The guy that did the conversion repairs heavy equipment and towed a JD 350 dozer with it, but only when his 6.2 was down.... I still have it. I have the cummins book for it if you want some specs.

 

Getting closer to setting this oil burner between the frame rails. I did start a half *** build thread in the 57-60 section called 'kinda like a hot rod but it isn't hot'.... The 4 spd is now coupled to the cummins. With info gleaned from a clutch specialty site (novack) I was able to determine I needed a TOB from a corvair. Todat I bought a clutch slave cyl to adapt and tomorrow it's an alternator bracket for a gm one wire. The entire nose has been pulled from the truck, but it still drives under it's own power for a while so I can move it around. By next week the 223 will be pulled and I will be figuring out the mounts for the cummins. Not a profesional mechanic or welder, but I'm a lifelong tinkerer and ford truck nut. I caught the diesel bug about 10 years ago. I have a 7.3 IDI 4x4 f350, a 6.2 in a grumman ex postal service aluminum stepvan, the 54 gmc with the 6at, and an 83 toyota 2l diesel pickup I bought for 150.00 and we dragged out last week to start driving again with the cost of fuel. Anyhow, take a look at my thread. I have had a bunch of fun in that group, but I'm afraid most of them don't get the diesel realm and instead concentrate on crown vic front suspension etc. I appreciate their ingenuity and awesome work, but some of you here might be helpful to me and enjoy what I'm doing with the more specific diesel stuff. Thanks, GB

 

Sitting nicely between the frame rails.... I will have to eliminate the fan clutch or fluid coupling and bolt a fan directly to the pulley/water pump and there should be no clearance issues. The engine is sitting on some 2x6s while I measure up for mounts and a trans crossmember. It will sit about 1 1/2" lower than the pics and about 1/2" further forward. It;s hitting part of the firewall now. The short driveline from the trans to the center bearing stays exactly the same length, but I'll need one of those conversion u joints because the sm 465 yoke is bigger. Inside the cab everything is great. Shifter is in good position and I'll keep the original e brake handle and mount it on the gm tranny(bolts almost line up already). I'm losing the driveline ebrake, but fortunately I had the presence of mind to coil up the cables on the sterling 10 1/4 and zip tie them to the frame. Amongst many other tasks, I'll be linking all this up. All in all a very easy swap with all kinds of room. This 120 hp inline job might not be for everyone, but it will do everything I need and should get excellent mileage. I can always take the '92 IDI if I really need to tow or haul a lot.

 

finished the mounts......

 

as awesome as your build is, you don't really need to worry about maintaining 2 different threads!

 

Didn't know you were watching the other one, and I figured this was only interesting because of the diesel aspect. This was really a hijack anyways.

 

oh yeah I kept an eye out for it! and i don't mind the hijack, i just know that it would be more work than necessary to post the same on two threads. but i really do love your build, me and my dad still have grandpa's 59 f350 and have been discussing what to do with it.
