You might try on the cummins site or even go to the top of this forum section and under the main header for power train you can find the information to come back into cummins. On their site they offer registration for owners for free and will provide about any information.

You will however want your serial number. My 8.3 ISC 350 has it on the end gear cover.

If you can get your engine number you can register it with Cummins online. They have all kinds of interesting information available there.

A Google search makes it pretty easy to obtain basic information such as this. Here's a link to a table that provides the torque and horsepower pairings for the entire Cummins engine line. Your 8.3L engine is known as the ISC and in configurations with horsepower in the range of yours it produces 800 ft-lbs of torque.

I wish that was true. Tried that with my ISX and nothimg shows up as warranty work, but I found a statement from a Cummims shop showing an engine repair for over $15,000.
