engine identification
 

I bought this 21 bolt, water pump in block(covered) Heads are numbered as for domed pistons Block has the pictured markings. There is a sticker on the head from a ford approved rebuilder. What year is this block ?

Think it would be very difficult to tell with the information you have posted. Keep in mind that external parts are easily swapped around.

21 stud pump in block is 37 and most 38 ford

I was hoping the block could be furthur identified by the photo of the block stampings I posted but expect that recast blocks had many different than original Ford stamps. It should have domed pistons but will have to remove the heads to be sure.

21 stud pump in block engines were exclusive to '37 & '38 cars and trucks, but continued to be produced for service replacement and stationary industrial engines. I have no idea how long they continued to be made.

They were manufactured long time in Canada and the UK. Both before and after the war. Ford casting numbers/letters of the era are largely a mystery about what they represent.
