Okay so im attempting to do some research about the Cummins 4bt. Im interested in the engine for my CJ-10a cuz the Nissan Diesel was junk. Anyone know of good sources of information or what these engines originally came in? Thanks for your help.

 

I know of a few small Cummins (not sure on model though) that came in bread trucks and the like...

 

yea thats the one! im doing research on it now and it seems that where they where most of the ones that you find come out of.

 

www.4btswaps.com they have all the info you will need. The engines come mainly from frito lay trucks and bread trucks.
