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....
Like them all, but love the "B"s.

Could a 21000 be used in place of a cat D333

Cat D-333 is the older version of the 3306 family and are 638 cubic inches. I doubt that you'd be able to install an AC 844 cube engine where a 638 cube engine goes.
