No. Starting in Nov 1966, the Monthly Serial Number/production reports started listing the beginning serial number for the month, of both the chassis S/N and the engine S/N, but the engine numbers do not always fall in sequence. Example: the 1st engine number for Mar 1967 was C159281, but the 1st number for April 1967 was C21738. The 1st number for July was higher than the 1st number for Aug, Sep and Oct. The engines were bought from Kohler, and were used in what ever order they came in the back door at the Louisville Plant. There was no attempt to match engine S/N to the chassis number, even on the farm tractors built at Louisville and probably the other plants. I don't know of a way to determine the build date of the early engines, the only published Kohler engine dating codes I am aware of start with the year 1965.
