if funds are all right im gonna invest in a 4bt cummins and use my 1 ton 79 axles 4x4 axles. unsure of tranny i know a turbo 350 will mount to them but might have to do some looking to see if a 700R4 will work. gonna put 20 in rims with 8 bolt pattern and put some military grade tires on it either humvee tires or gonna run the duece and a half tires. then im gonna have a local shop build me a 50 gallon fuel tank. any input on what you guys think. any ideas on how to improve or change around

that sounds pretty sick! I dont think i've seen any like that. what would you do for bed?

TH350 and 700r4 are the same pattern. Advanced adapters has a plate fro 4bt to GM trans. Spline is 27 out for driveshafts. Sounds like a cool build.

The older trucks that run those engines run Turbo 400's most of the time. The newer ones run Allison transmissions though.

Sounds like an awesome build!!

I like the way you think

A nice used 50 gal fuel tank should be real easy to find in one of the junkyards that specializes in big-rigs.

Im gonna build a custom flatbed for it. and the local shop said that they could build me a decently priced fuel tank because i want to build it into the flat bed. thinking maybe part of my headache rack. so its centered in the frame.
Another opinion would it be better to buy a cheaper 4bt and pay to rebuild it or buy a already rebuilt motor? oh and i forgot to mention im planning on putting a turbo on the 4bt

Hey Midgets50, don't know if you would be interested but I have a factory flatbed off my 51 that I am not gonna use.

Please don't use the 700 behind that diesel. There's a reason GM only used them for a couple of years and they weren't really that successful.

Midgets50 · 01-19-2013, 08:35 PM

whats the gearing in the allison gonna be like compared to the 700. im kinda looking for something that will still give me decent mileage. i know the big tires kinda kills that. i dont remeber who exactly i talked to but he was running a 4bt in his 4 door wrangler with 38's and pulling a camper or some kind of trailer he was getting 28 mpg

First let me say I like the idea and it would make for an awesome truck. I am saying that partly because I kinda' want to do the same thing but also it just seems to make sense for a heavy duty driver.

I purchased a 2000 dodge with low miles (120k) but the tranny was shot. This truck had pulled a 30 ft. travel trailer about 110K miles. They claim the 47re is weak but many of these trucks have been used and some abused. The aftermarket can make these transmissions very durable. I not sure if the 47re will fit the 4bt, but they are supposedly the same engine minus 2 cylinders.

I am driving the Dodge now and looking for a 47-53 cab. I need to finish my 3100 before moving to another project.

My dodge gets about 22-24 mpg (at 65-70) on the highway but it has to be in over drive (it weighs 7k lbs). I really think you need a trans with OD to get the mileage.

If you do not already have the motor have you thought about an older 12V- 5.9? I see the motor and trans for sale on Craigslist for reasonably prices. The older ones do not have electronics. I am not sure of the year model but I sure you could google that. I do understand using the 4bt if you want something different or if you already have it.
