    Straight 8 cylinder head identification

    Hello All,

    I have 2 extra straight 8 heads in my shed and I am trying to id them.

    One has casting # 1318766-1 on it and it measures 31.5 inches long. I believe this is a 263 head . . .

    The other one has casting number 13408273 on it. I donít have the length on this one and Iím not sure what it is for . . . This one is fully rebuilt and ready to go, but donít know what it goes too.


    Any help on the identification of these heads would be great!

    Thank you,

    53_Jeff

    would suggest that your 1340827 head (disregard the number after the dash) could be a 1951, but you will still need to measure it to find out if it is for a 263 or 320.

    1318766 is 263 50-53

    I am not finding anything on the other number.
