Block stamping question

[nlneeded]

Hi everyone, new here.
Question I can't seem to find an answer on, I have an older 283 block which I am trying to identify.
But question is, on the top front ridge of block where the manifold would mate to there is a 040 stamped into it.
Does anyone know why? I never seen this before.

Thanks
Dave

Hi nineeded,
Welcome to the forum. The numbers you speak of are assigned to that particular block from the factory to the foundry as a 'run-number' as far as I recollect and has no significant meaning as a builder or restorer. I could be wrong on this, it happens quite frequently. If you don't believe me, ask my wife :lol:.
