to my knowledge none. the C&S never had anything bigger than 74 (an arguable point but considering the contender is no longer in existance.... ) i belive the largest engins of a conventional nature able to fit are the 40 and its sisters but if you had 9 60 71 and 74 on the property in an "operational rotation" (as in three runnin one down for heavy repairs) this way you can run them a bit under tonnage and still keep up with rider flow and reduce the risk of causing damage outside normal mechanical wear
ahh for dreams to come tru
