    Early sixties merc 400 and 500 differences??

    Can anyone tell me what the differences were between an old merc 400 and an old merc 500?? The block is the same part # so I am assuming that the intake side of the crankcases are the same. The exhaust baffle plate #'s are the same as well, so I don't think there is any difference in that...
