Hey Greg,
Of the 3150, and 3208 my choice would be the 3208. This engine got a bad reputation in the over the road trucking industry, mainly because of being underpowered for the application, the &#039;big&#039; version was only 325 HP. They are a great engine for dump trucks, local delivery trucks, power generators, pumps, and yes, AG equipment. I had 2 of these engines driving 250 Kw power plants, a little over 4500 hrs a year for 3 years without a minutes problem, then traded them for 3408&#039;s with 375 Kw plants, once they had no depreciation left. Whether this is a good engine or not I feel has alot to do with application. In a 2255 Oliver a 3208 should easily put 250 HP on the ground, with only slight modifications. As far as the 3150, I would say it is a good engine, just not as powerful as the 3208, which once again becomes an application issue.
