    I found a fairly complete 273 commando with block cast number 2465330-3 and below left side head stamp number A2731022

    Before 1968 I believe, vin numbers weren't stamped on engines. That is a plain old 273 that could have came out of pretty much any A body. The engine has some value to the right person as well as the Commando components.

    Also on the front of the block (near head on driver side) it may be stamped A-273, B-273, C-273 etc.

    To confirm it's an actual Commando, you'll have to check to see if it has the 10.5:1 hi-comp pistons, etc, that all true Commando's came with.

      Correct, the blocks, cranks, rods, heads are all the same.
      Commando = Pistons, cam, intake, (valve covers, carb, distributor, air cleaner...)

      Appears to be an aftermarket intake on it, but the real test is having the "domed" hi-comp pistons, dual point dizzy, slightly hotter cam, etc, etc. I see in your other thread "31" under "AB", so I believe that indicates the car came with a Commando engine.

      Also appears to have been changed over to the more modern dual braking system. The original would have been a single pot master cylinder. Good feature!

      The power disc brakes was a dealer option...
      On the tag under the letter “C” has the number 5 which is power brakes option

      You can have power disc's, but you'll still have the single master cylinder.
      Kinda hard to read that, but I still maintain the dual system master cylinder was not available 'til '67...just the single pot unit up to then...

        If you have a snall enough boroscope, you could look through a spark plug hole to see if the piston is domed.
