i just acquired two ford flat head engines one is complete with 59 stamped on the belhousing also 59 ab on the heads pretty sure this is 1946-48 engine the other is just the block I know it's a 24 stud but it has a "B" stamped in the front the block also had HS104 stamped next to it. Any help would be greatly appreciated
Describe center vertical row of water holes in block and measure bore with ruler Look at bottom, pan rails...are there two freeze plugs in each, or nothing? Manifold surface...flat all the way across block, or gasket area higher?? Oil holes at back...two regular holes, but is there a raised boss for a third, or even a third hole?
HS probably stands for hardened sleeves. These are the thin steel sleeves. They started in 1938 and continued through until 1941 or 42.
