Asking here as this is a recent thread and no sense in starting another “what flat head do I have”. I haven’t seen any references to cast in numbers/letters on the block flange where the bell housing attaches. My motor has the letter “M” cast in the 12 o’clock position and “M2824” at the 10-11 position. On the intake deck passenger rear is stamped a box with a 4. It also has the Mercury heads. It’s in my ‘39 Tudor Standard with a Ford carb 94 with and Autolite tag 8RT 9510 F and a 8RT /8BA intake. So I know 8RT/8BA. Any comments would be appreciated.
