That is a strange one. M would indicate a 54 engine but even so, the numeric range is way higher than any listed end number. Kev has 321199 as top but for some reason the Kimes edited book doesn't list an end number in the M3 series.

Wonder if they built some service replacements with an M designation but a high number. There is very little info on how service engines were numbered. There is a Studebaker bulletin referring to replacement engines in the 300000 range but we are missing page 6 in the bulletin which gives the details. The H could mean hydraulic option was installed as M3 would be the solid lifter 327 in normal designation. There was a bulletin saying all replacement engines had hydraulic lifters though but no info whether H was still used in those engines.
