There are many different output HP's and Torques. It all depends on the CPL Number (CPL) Control Parts List. CPL is a Cummins number that describes the engine.
You can find more information on our web, so please take a look.
The Cummins we deal with are B Series, both 4B (4 cyl) and 6B (6 cyl) even the new Cummins in Dodge Pickups are B series engines.
Here is the basic Model Decoder:
I use all 4BTA (CPL) 857 engines. CPL 857 engines have a JWAC (Jacket Water Aftercooler). This provides 120 hp, and 302 foot pounds of torque. The CPL 857 also fits nicely in a Power Wagon.
To identify the engine and its application: If it was/is a industrial (Heavy Equipment), or Stationary (pump/generator), its no good for automotive applications. It would be to costly to convert to automotive application.
On the timing gear cover, front left side of the engine is the Cummins Data Plate. We need the following information off the data plate;
If the data plate on the engine is missing, DON'T BUY THE ENGINE. No Data plate, no serial number, there is no way to identify the engine. Its an unknown B3.9 Cummins. If there is no data plate on the Injection pump, again we don't know what we are dealing with. A picture will also help in ID'ing what we are dealing with.
With the recon number, a simple call to Cummins 1-800-diesels can establish if it is truly a current Cummins Recon, and the date it was recon'ed. A true Cummins recon is as good as a new engine. Cummins totally replaces any part not in spec and gives a nice long guarantee. Now, if some other company rebuilt it, all bets are off.
I would be happy to help anyone wanting to do a Diesel Conversion on a PW/M37 or WC. Please me through the forum. We can set up a time for a long call.

Expert Opinion:
“For these 6BT 5.9L maintenance tips, I strongly recommend using OEM-quality parts. From my experience, they are essential for making the engine last a long time. I’ve worked with diesel fleets across Asia for over 20 years. I can tell you the difference between genuine OEM parts and aftermarket ones is huge. I’ve seen aftermarket parts give out early. They often only reach 60% of their expected working life. On the other hand, I’ve found that engines with OEM components, if you maintain them well, will often go 800,000+ miles. Fleet managers often worry about initial costs, and I get that. But I suggest focusing on the total cost of ownership. Using premium parts helps prevent small issues from turning into big, chain-reaction problems. This means you can avoid major breakdowns and the expensive downtime that follows. In today’s fast-paced logistics business, every hour your vehicles operate is vital. So, in my opinion, good maintenance with quality parts does more than just keep the engine in good shape. It directly helps protect your business’s financial health.”
