How much should I expect to have my flathead six rebuilt? There are gobs of info on rebuilding the Flathead V8, but nothing I can find on the Flathead 6!!! I just purchased a 1949 F-1 that I will be doing a restore/customize on. Since I already have this motor and trans in the truck I might as well try and use it! Anyone ever had their Flathead 6 rebuilt? The previous owner said he almost go this thing running but that the starter didnt want to turn.
