    Hey all dont post much but was curious about the 63 buick 225
    found one should it have 401 or 455? which is preferred?
    its a 4 door but pretty cool ride only 37k orig miles clean as a whistle body.
    might mess with it says runs but Needs trans work probably leaked fliud out.
    Thanks

    401 most likely , 445 on the air cleaner lid is the torque rating . No 455 engines that year.
    Possible 425 engine would have 465 torque rating on air cleaner , not sure the 425 was available
    in 63 .
