So, I know that I will need Motor mounts and transmission (Or a big-block bellhousing for my 4-speed).

But will the Radiator, fuel tank and lines, and front axle be up to it? on a dodge site I was told that gaspot front axles are rated for 3000-something pounds, while diesel axles are rated for 5000. Considering I don't have the door sticker anymore, I don't know if those ratings are for Dana 44/60, or if there are two different Dana 60s that were used in these trucks. :confused0006:

Another question is, whats a good price for a running 12v Cummins engine? The one I found is selling for $2450, but that is all included.

Whaddya figure? [cheers]

unless youve got a lot of money/connections, that swap is gonna knickle and dime you.


You need a 60 front,new motor mounts, gonna have to fab up a new crossmember for teh tranny, new drive shafts, wire it up,gauges,new front leafs,better front shocks,might have to change the crossmember,have the KDP tab'd... still interested?

You're gonna spend easily 5gs on teh swap,

motor/trans/tcase=3gs
dana 60=1g
misc.=min 1g


edit-my friend might have a wrecked VE cummins w/trans that he might be willing to part with

I have a 60 already, and I think the NP205 Tcase will hold up to the power.

89-93 cummins: 12v, bosch VE rotary injection pump. Autos where 727 and 518. Standard trans was the getrag g360 which was alright but its max power input is close to the cummins' 400ft/lb.

94-98.5 cummins: 12v, bosch p7100 inline injection pump. Easier to mod and get more fuel out of. Trans' is the nv4500, dont bother with an auto.

89-98.5 where mechanicaly fueled, no electric injection pumps. Easier for you to swap, 99 and up had vp44, cp3s.... etc.

if i where you, i'd fine a 89-93 model with the VE rotary pump because my understanding is the fuel pump runs off a diaphram in the crank case, so once its getting fuel it needs no electricity.

But, if you run an fuel shut-off selenoid and it doesnt work, you have to climb under the truck and starve the fuel pump. My suggestion, run a cable to shut the fuel off. Simple, easy, cheap and reliable. Look on pirate4x4, i read a write-up a couple months ago and it was informative.


To see if a cummins is good, i'd do the following:

check the turbo impellor for excess play and fuel pressure test. The engine will have to be running to check fuel pressure.
