This will take you to the menu. Scroll down to 1943 dodge carryall for the Cummins Carryall pictures and a little further down is the M37 Bandit Cummins Build.
By all means you want a Automotive application Cummins. Forgetting all about different injectors, turbos etc, the most important difference is the Governor setup. On a automotive engine, the governor limits the maximum RPM to the Cummins Spec. You control the engine speed !!! On a Industrial Cummins, such as one used on a pump, generator etc, the governor is designed to hold the engine up to a design RPM. As a load on the engine is increased the governor will apply more power to keep the engine at the design for application regardless of load up to the max Cummins spec for RPMs. Typically these engines are designed for idle and the top design RPM. This would be unruly, and very dangerous on a automotive application. An Automotive application requires infinite speed settings between idle and max RPM.
A Marine Application will typically have a different injector and larger injectors. Its also setup with water cooled exhaust manifolds that get their cooling either from raw sea water or a marine heat exchanger. The expense to convert a marine application to automotive would be very expensive. Hold out for a Automotive Application 4B Series Cummins.
GM vs Dodge NV-4500. Early GM NV-4500's had a very low 1st gear. Later, I believe 1996 the 1st gear in GM and Dodge was the same. There are other differences such as output shaft size and spline count. But in my opinion the one very important item to understand is starter location. All Cummins require a Flywheel Housing Adapter for the Brand transmission you will be using. All GM Applications place the starter on the right side of the Cummins (passenger side). All Dodge applications place the starter on the left side of the Cummins (drivers side). If your using a Saginaw Reverse Rotation power steering box, you will have space conflict with the starter on a Dodge Application when mounted on a WC, PW or M37. This can be overcome by mounting the Cummins/NV-4500/T Case, 1.625" to the right. Then you JUST have clearance. The GM Application with the starter on the right side does not have this interference issue.
I have all the part numbers (NAPA and Dodge) and will share all with you. I will help you in any way possible to achieve a Great Conversion ! I suggest we do a telephone call. Its way to much info to try to pound it out on a keyboard. Email me ( ks2krpt@attglobal.net )and we can set a time for the call. Be sure to put Power Wagon in the Subject line so its not trashed as spam.
