    401 Pistons Wanted

    I am looking for a set of .30 stock cast 401 pistons.

    I was told by somebody that I need to look for the 1971 pistons because they have less of a "dish" and I can get around 9 -9.5 to 1 compression ratio with the later 58cc heads.

    Anybody know if this is true? If it is, does anybody know where the "hot" deal is on them?

    Thanks,
    John

    401 compression

    Yes as far as I know the 71 401 came with the 50 cc heads and less dished piston dome for a compression of like 10.2 to 1. The 72 401 had both a deeped dished piston and 58 cc heads resulting in a compression of just below 9:1.
