"guys is their any way to decode the "stamped #'s" on a 235?"

I think that only (3) is stamped/pressed into the block; and, (1) & (2) are casting numbers (not stamped").

(1) The block casting code, 3836233, was used on 1955-1956 truck blocks (this guess came from information found at various reference sources on the Internet).

(2) F 2 55(above starter) june 2 55' - sounds good to me

(3) 033804I755Y
might this be 0338041 F-or-T 55Y ? That would be a Flint (MI) or Tonowanda (NY) built engine used on an early 1955 1508 series sedan deliver with a Powerglide transmission (does it have hydraulic lifters)???

(4) Nonetheless, it is most likely a 1955 235 block.

(5) A 54-62 235 head will bolt to a 1955 block. The rocker-arm assembly and oil feed connection to the rocker-arm assembly might have slight differences from 1954-1962.
