i had a C-18 built from a s/n feim Oshkosh 950 hp and 2,400 ft lbs at 1,400 rpm. In long hood Pete pulling my 9 axle lowbed. Loved that engine. BuiltSS headers, ran two parallel turbos, separate stacks separate air-cleaners. Fkn awesome! Google Chrome For Kids Burnout. Or Daryl Wear Contracting. My old company. My wife ranmy pilot truck and she hated that Pete, always issue for her to get by me loaded on hills lolLenny, I think two of them are very similar to what you have, the third one seems to be built only for oskosh and is 950hp with split manifold twin turbos on it, it uses what everyone considers to be the 1000hp cam and very large injectors, and revs to 2300rpm.
