drip castings inside were ground off to clear roller's. definitely could use some polishing. 427 cast in them as well as M/T .. these are not copies and have been on this motor since 1974 and the original owner of my boat said he just threw them on there because the motor needed some and they were sitting around his garage for a few years so they must be pretty old. i think i remember seeing a small spot where one was repaired or the casting was blemished the only time i had them completely off. but i could be wrong and can look again.
anyway $75 sounds fair to me...i'll even throw in the bolts and bitchen oil fill cap!
