I am thinking of purchasing a 99 longbed with a V10 as I think I can get a steal on it. Currently I have a 2001 shortbed with the 24v Cummins. It may sound like more work than its worth but I would like to swap the drivetrain's on these two trucks. I have found that my family and I would like the room of the long bed for the stuff that we do so this may be the perfect truck. I hate to asume, so I am asking for confirmation. Can I take my Cummins engine with the 47RE and transfer case as one asembly and drop it into the long bed truck as a direct bolt in replacement? The long bed has the V10 with the 47RE and transfer case, and I would probably put that drive train in my shortbed and then try and sell the truck. I am asuming that the frame's are built to take either engine but I dont know that for sure. If I have to do any welding and fabricating of engine/transmission mounts then I dont want to do the project. Also, does anyone know what complications this causes to the vehicle title and State emissions and inspection stuff. I realize that is a question more specific to my State, but I am just asking in General. Thanks

 

everything simply just bolts in, the drive train should be exactlty the same between the two trucks, except for the gears may be different, my v-10 had 3.73's and i love them behind the cummins, even the trans from the v10 will bolt up to the cummins, but you would need to swap the valve bodies as they dont shift at the same rpm's, but short answer, yes it will work if you want to spend the time to do it

 

Just what I was hoping for, thanks for the info. Can you tell me anything about titling issues that you may or may not have had when you transplanted the cummins into the truck? Thanks again.

 

might be easier to lift off both cabs, swap motors on to the frames then drop the correct cab back onto the correct engine, this would certainly eliminate the pulling of wiring harness/ hyrodoost (if the gasser does not have one), might be much faster and easier,

 

This is a major project, very time consuming. the wiring harness is different on both, so that means instrument panels and under dash wiring to be changed, plus all the other wiring underhood I did this with a couple of fords 5 or 6 years ago. I wouldn't do it again instead I would sell your truck and but what I needed, you'll have both trucks down for quite some time.

 

the engine/trans harness is very simple and will connect to either truck, the gauge cluster is different but will swap out between the two, the only thing the wait to start light will not work, no harnesses need to be changed other than the engine/trans harness, the engines will come out with out pulling cabs, the cummins is very tight, but if you pop the oil pan and pickup tube off (very easy to do) and unbolt the enginemounts from the block, it will just slide out

 

Good!
