Hi can any decode my 24 stud flathead V8

casting in centre 12 o'clock rear of block either O or C

followed by a casting R/H rear of the block M1294

The answer is no. Those numbers have meaning only to internal activities at the casting factory unit.

Do a search on Google for "flathead identification Ford barn" there's a good thread on here with all the info.
I use the Google way as it seems to work better than the search function on here.

What Martin said, but it is going to help you ID the engine by characteristics of the block, not numbers cast or stamped into the block in most cases.

Shapes of water holes near center of decks, plus presence or absence of this stuff will ID a prewar 24:

2 Vertical ridges on each side of block leading to freeze plugs on pan rails

manifold gasket shaped cast pad on top of block where manifold goes

Small round boss near oil sender holes at rear of block

what does small round boss mean?

Think he is referring to the one I have drilled out in this photo. This block came out of a 48 truck.

Bruce Lancaster · 09-22-2016, 02:45 PM

No proof, but I believe that boss came along in '42-3 for military carriers and heavy trucks using a cooler or full flow filter. Many of our '42 "raised deck" engines are actually WWII survivors.

I just dismantled a '59' block standard 3 3/16 bore and has the round boss. didn't notice it until I saw Bruce's comment. so many variables with these flatheads!

Do you just have an engine or might you also have the car. We can answer most questions but photos or characteristic information will get quicker answers. Welcome into the barn.

On that boss...if you carefully scrutinize the pictures, you will see that the engine used for many of the photos is a '42 type block with all 3 oil bosses open...it is a wartime motor, probably from a Canadian carrier or truck!

Bruce, Every Universal Carrier produced by Ford of Canada had an oil cooler and the third hole in the block. The first one rolled off the line on 8th Feb 1941.
Prior to that British built carriers (many of which were lost at Dunkirk) had oil coolers. The British supplied specialist parts (which included the cooler bypass valves and oil coolers) for the first 1200 approx Canadian carriers.
Basically the third hole in these blocks I am guessing was a British idea, because they were using oil coolers with Ford V8s of British origin in 1938. New Zealand received 6 British Bren carriers in 1938.
Ford USA supplied GAE-6004 US engines and GAE-A-6004US engines in this 3 hole style to Britain for installation in carriers early in the war.
Maybe someone has info on the build specs of these two engines? I would love some details. They both had 14mm plugs and probably std. American electrics.

The universal carriers ran warmer due to the way the cooling system was designed so they used oil coolers from early on to augment cooling duties so they could operate in harsh environments of the tropics and North African desert. A lot of the Canadian production used them in CMP trucks too. Many of the vehicles produced by Ford USA had 4-cylinder engines or 6-cylinder engines such s in GPW jeep type vehicles and the G8T trucks. Ford USA still manufactured V8 engines during the war but there is not a lot of information about how many or for what vehicles. It's known they manufactured fordor sedans and several types of trucks for fire engines and other purposes too but not a lot of info there either. Ford Canada made a lot more V8s than Ford USA and in more than one configuration too. Ford USA converted to build tanks, B-24 aircraft, and Pratt & Whitney radial aircraft engines as well as GPW jeeps and G8T trucks. Ford USAs big V8 GAA tank engine was a work of art.

The little undrilled boss in the 59 series engines was a carry over from war time specifications. It makes it easy to add a cooler or a partial flow oil filtration system if a person wants one. On the blocks that don't have the boss, you have to be more careful about drilling in that location but it can still be done.
