    Default Are these cylinders correct for a 1946 Chief?

    Indian parts books show 93070/93071 and 93072/93073 as standard and Bonneville Chief cylinders, but could not find the casting numbers that are on my cylinders; 93074 and 93076. Are they correct for a 1946 Chief? Thanks

    Hi Shane,

    I have the exact same question :-). My 46 chief has the same numbers 93074 and 93076 on the cylinders.

    Regards,

    Those casting numbers were on all chief cylinders from 1940 on. Even if there were changes in the cylinder the numbers stayed the same at that point. You must know the individual characteristics of the cylinders at that point. Only noticeable changes were the early forties used the round base, the war years the window style, and then 46 and up same except higher compression 52-53 where the land area for the head was cut down to up the compression.
