6bt in CUCV

I'd love to see how this turns out!

I would not do the swap,unless you have tons of cash and time to spare. I have a strong mechanical background and have retrofitted 2 different engines into a 71k5 rock crawler build that took 12 years. I have the nv4500 now behind an LS 6.0 a good set up but do not need 5th with 42" tires.

Hey Cletus09, I see you're in Norton. I'm right next door in Barbertucky. You wouldn't happen to live near the Old Stone Jail, would you? I've seen someone near there with an 08 and an 09, but haven't had a chance to stop to look at them. Hit me up if you ever have questions or need help on yours. I've got an M1010 and a M37.

just goto youtube and or internet search cummins k5....HUNDREDS of people if not more have done 4b/6b swaps into square bodies at this point....all it takes is $

Also don't worry so much about the "redline" as you put it. A 6BT can rev to 2700rpm all day long and never skip a beat. Actually with valve springs and adjusting the governer (as well as a good damper) they can be pushed up to 4K. Fuel economy is what suffers though.

Agreed! The bottom end is good for 1000hp! The guys running in the badger state super street diesel class have been doing it for years! Indisructable if you can keep em cool IMO!!!

These guys make the motor mounts + trans dapts to any GM trans except glides and 350's. . . . Just use proper judgement w boxing frame for long term. I was thinking about a manual valve body 700R floor shifted would be cool behind a 4b or even 6b. 700R4 can handle 1000ft lbs all day if kept cool and 'dumb' inside.

Thinking about buying one of those p30 bread vans with a 4bt and swapping it. I hear they bolt right up with the th400s and a 4bt would be a better to modify/build up seeing as how you cant squeeze much power out of a 6.2. I've seen a 1009 with a 6bt but the guy reinforced the frame and threw some bigger axles under the truck. I believe he fabbed up some motor mounts too. Just my but a 6bt would be great! if only I had the time and money...

A 4bt would be a good choice in a 1009. Don't want to be too front heavy, and the modifications will be less. 4bts can be souped up too.

Need I say more....DO IT !!!

These GM 6.x motors are a poor excuse for a diesel. My biggest regret when I did my NV4500 swap was not using a later model NV4500 with the universal Bolt pattern.
A fully built 6.2 runs like a worn out Cummins..
This guy is a friend of mine. This truck is BADAZZZ!!

If your looking for a cheap 4BT I was out at Bergen auto parts and they we're pulling about 10 of the bread trucks apart with the 4bt's in em, I think they said $1200 incl the tranny.
