Is this VIN a 68 340S?

`69 is where things get confusing for me , I`ve seen 340 Barracudas with both "`Cuda" badging and/or with one formula-S badge on the right rear deck lid. Were P, H, and M-code cars "`Cuda`s" or Formula-S cars, or are they one in the same? Didn`t the P-code 340 turn into an H-code once the 383 was extinct?
