I have a D2AE-CA listing here mabey it's CA instead of CO.
The D2AE-CA casting number is listed as 71-4V 351C.
Also it is listed as 72-74 351C Boss,71 CJ, HO and 72-74 4V 351's. They are all 4 bolt mains.
Either way it should be a good motor. Check the last 2 letters again the C could look like ab O.
