I have an opportunity to pick up a flathead Chrysler that was used in a wooden power boat from the late 40's. It is marked "reverse rotation" and was used with another engine that went the normal direction. Does anybody know what was changed to make it go backwards and how hard it would be to return it to "normal"? I'm thinking it's the cam and distributor... is there more? Do the oil returns run up-hill?
Thanks!
