Hello all, i have a question that I hope someone can answer. My 07 got ran out of oil and seized the crank, but later freed up and now has a rod knocking..only 75,000 miles on it..anyway my girlfriend(responsible party) is paying for new engine. We found on craigslist here locally a 6.7 that was used in a school for cummins techs..so has no mileage on it, just some run hours on stand...but here is my concern, iam wondering if cummins made a different 6.7 for like 18 wheelers, or other industrial uses. There is a tag on the engine that states 190 hp, and as you know the ram 6.7 is rated 350 hp. Also there are differences inthe intake manifold, exhaust manifold and the harmonic balancer....which i know can and will have to be changed. The exhaust has the turbo mounted right at the head between cylinders #3 and 4...Anyway does anybody know if this engine will work on my truck? I have serial number of engine and more that are on the tag...thanks all
