help with engine #

for quite some time i have been trying to decipher the engine # on my 52/200. i have wire brushed, sand paper, and chalk. my car has auto trans. does this # make sense?
M344377H
i believe the # should start with J4 , but i don't see that no matter how hard i try.
Does the H mean i have hydrolic lifters....?
the packard record keep-er told me to get the production slip off the top of the glove box.... wow it is so so fragile i did not want to force it. any advice on how to do this. ????
thanks for all your input in advance.
