1930 Ford Model A help?
I have a 1930 Model A im making into a hot rod im starting the engine work and i need to know how far i can over bore the engine i was looking at pistons from Mac's auto parts and they go to .125 is that ok to go that high? will the walls be to thin and
Im assuming that you are referring to the original 4 cylinder flathead engine. If so, then don't go any larger with the boring than absolutely necessary for a good cylinder clean up. There are not maany of these engines left, and they were'nt engineered
