I think I have a '57 235 cast on Dec 28th, 1956 and assembled in Tonawanda, NY on either January or September 23rd. I'd like confirmation from those experienced members of Stovebolt. Here are my numbers:
Block = 3837004
Casting code = L2856
Serial # = TI23H (the second item really looks like an I rather than a 1 .... could I = September vs 1 that seems to mean January)
Questions:
1) Before the casting code is CONV1 .... what does this mean?
2) Just forward and above the fuel pump is a 1" x 2" plate riveted to the block that states SUN MOTOR SUPPLY, TULSA, OK with two numbers on it, in the lower left 57008, lower right CH20 ..... any idea with this means?
Thanks.

If it were September then you would have a block that was cast in 1956, assembled in 1957 and probably installed in a 1958 vehicle.

It wasn't uncommon to see an "I" stamped on these engines when it it's really suppoed to be a "1". The number on mine is stamped like that as well, with an "II" right in the middle of the number. The "H" in the code means it was originally from a '57 1/2 through 1 ton pickup with manual transmission.
