Julian date coded 409

Block 3844422 is 1963 or 64 or 65...correct? Jullian date code 325. Both heads 3830817 (QC)... left Julian coded 324 and right Julian coded 353. Since the TXXXXQC stamping gives the month and day but not the year, in this example how can one decipher the casting and build year?

OK thanks fo the info but please educate me.....why coulld it not be built late 1962 for 1963?

The 814s came out after the first year of production of the 068 blocks, and most 814s went into the 1963 models, then after that came the 422s in 1964 and finally the 656 castings in those last years (as it pertains to 409 blocks).

4422 motor is late 63 or 64 motor, not 62.
