In their stock configuration and the way French flathead blocks have been sold previously the bosses, casting numbers, and pads for military applications do not fit most Ford passenger car applications without firewall modifications. SF Flathead blocks are precision milled to remove the unsightly “lumps.” Only a pad remains that carries a SF Flatheads serial number. Stop searching for a savable old Henry lump. This strong, high-nickel casting is the last flathead block you’ll ever need! Please call for availability. Truck shipping required. Rate quoted at order.
