Ford, GMC, Chevy, Pete, KW, Wester Star all had Detroits in their engine line-up, the main being the 8V71 because of hp rating of 318 which wasn't far off from the 335/350 Cummins and Cat 1673 @325 hp.
But GM/Detroit would sell to manufactures $500 to $750 less per engine. The Cat 1693 was looked at as a owner/operator spec engine at 425hp, same with the 12V71 and Cummins KT/KTA 450 thru 600 hp
engines. When Detroit came out with the double OO 8V92 it put out power but was nothing more than a 8V71 block and rods punched to accept 92 liners. The 71 main caps did not have enough material
to handle the horse power and main caps cracking was a real common problem. Then came the Silver 92 with redesigned block and heads but because the double OO series had a bad reputation it didn't
sell well till Detroit threw a 200,000 mile warranty at it, then sales took off. Plus Detroit re-rated it to 475 hp which caused owner operators to take a second look. But even with all that said it made a terrible
engine for on highway use. It's a two stroke and those don't like to be idled plus those engines don't like constant rpm swings or to be pulled down and run at lower rpms. Those engines will last and perform
much longer with constant high rpms. Years ago talking with a Detroit rep the on road rated two strokes were designed/planned to burn a gallon of 30-40 wt every 3,000 to 3,500 miles.
