Any ideas on how to work out if this engine is a 340 or 360 (73 Challenger)

I have tried a lot of the decoding sites but no joy

The plate below the white sticker and bar code has the numbers 2211 and then 469923

Any help on identifying the engine type and year would be much appreciated

 

Just found a video that may point you in the right direction:

 

Look on the side of the engine block to the rear of the engine mounts and see if it says 340 or 360 in the casting...

 

Got it thanks, Says 360
