There is one on an Oshkosh truck that powers the snow blower. I believe it’s on Sullivan auctions.

21000 was a 844 cubic inch straight six cylinder with a turbo charger. One use was in the 21C Dozer at 325 HP ....... similar in other applications... If you wanted MORE HP, you changed it to a 25000 which was the same engine with an intercooler to lower the air inlet temp after the turbo....
