    346236.....75-87...oval...OPEN...454, 120cc chamber, 225/116cc ports



    I'm gonig to go with ...you read it wrong. Often old head castings need some "Eye Trickery" to read.

    Could it be "346246"???
    If so it comes back to:
    75-87...oval...OPEN...454, 120cc chamber, 225/116cc ports
    According to mortec.com
    The "120 74"...
    I think it means Jan. 20, 1974 if memory serves.
    That would match close enough to a 74 engine.

    Edit...
    According to nastyz28.com the code with a "3"
    comes back on a 74-67 454BBC
