There is a stamped serial number at the back of the block below where the cylinder head bolts on which reads 22JJ77. Page 11 SPECIFICATIONS SECTION Model 351/4 302/2, 302/4 Bore 4.00” 4.00” Stroke 3.50” 3.00” Cubic Displacement 351 cubic inches 302 cubic inches Horsepower 240@4400 RPM 175@4400 302 2/V 220@4400 302 4/V Intermittent Service 4400 4400 Continuous Cruise 3600 3600 NOTE: Do not cruise at high limits of above range unless propped to turn at. The first number will tell you the year. You do also have to remember that ford sometimes put engines left over from the year before in their cars. To truly tell if it is the original engine a partial vin number is stamped on the rear of the block on the passenger side right below the head on a flat spot on the block. Hope this helps. The 351C block casting number and date code are located just above the starter. This D2AE CA casting number indicates a four-bolt main block according to the Ford Master Parts Catalog, but not all are. This casting date code “2F30” means February 30, 1972. This is a head-on view of the 400 Cleveland block, which has a 10.987-inch deck height.
Ford kept track of the various parts and castings in its inventory by assigning each item its own unique alphanumeric identification number. These numbers provide a lot of information to those who are familiar with what the numbers mean. The unique identifier is a series of numbers and letters that are put in a specific sequence, and the location of the digit determines what that digit designates. Information commonly provided by part numbers includes the decade during which the part was designed or manufactured, the year of the decade the part was designed or manufactured, the car line the part was originally designed for, the engineering department originally responsible for the design, the basic part number, and the changes made to the original design.
What can be confusing about these numbers is that a part designed for one year might actually be used for several years, or a part designed for one car line might be used on other lines as well. For instance, a part originally designed for a 1964 Ford could often be found on a 1964 or 1965 model Thunderbird, Mercury, or Lincoln as well. It is actually quite common to find parts originally designed for Thunderbirds on Lincolns, and Falcon parts on Mustangs. In order to spread out the costs of designing and manufacturing a part, Ford used parts on different models.
