ulss tractors can run basically whatever you want as long as its under 650ci and loosely came in a tractor. The engine doesn't have to match the hood on any class running a component chassis(non ag rearend). The rules originally only allowed engines from 2wd tractors. But somehow a 903 cummins got in which was used in 4wd tractors and now there a handful off them.
