You guy's are terrific! Thank You especially thatdarncat for doing the web searching/links
Bothers me the reproduction mounts could sit differently and suddenly I have header clearance issues or clutch linkage issues etc..
I know, Murphy's Law, mine will show up the day after I get another set...
My Marine 427SO's are the real deal (nothing,nada,zilch center oiler at all)
I've only heard of one other pair of true side-oiler Chris Craft 427's like mine in somebody's hands. Oddly I guess, I have never seen a sideoiler block drilled as a center oiler.
I'll just keep looking for mine and keep in mind where I can get replacement.
