Matching Numbers???
2465330= the casting part number of the block. The 65 has nothing to do with the year of the block itself. There are no hidden messages in the casting numbers of block castings. As stated, 2465330 indicates a 273 block for 1964-66. Now, if you'd like to date that block, look under the drivers side cylinder head on the front of the engine. Right below the cylinder head there will be a couple of stamped numbers...A=1965, B=1966, then the displacement which should be 273, then the assembly date. I am not familiar with what 64's were stamped, but I know that 65 motors started with "A". In the included picture you can faintly see the information of my block. It is a 66 (B) 273 with an assembly date of 1-14. Hope this helps, Geof
