What size engine is this the number off the head is EAB 6050D 4OU. I think it is a flathead 239 but am not sure.

 

Should be a 239 flathead V8. If I remember correctly, 8BA heads were cars and small trucks, 8RT heads were for larger trucks and EAB heads just had larger compression. I believe that the EAB heads are the best of all three.

If I'm wrong, then someone will be along shortly to correct me.

 

Thanks for the information Panelman that is what I thought it was too but wasn't for sure.

 

I had thought (and this is fairly loose in the knowledge department)...but, I had thought that the 8BA heads were used on the 239s up to 1951, the 8RTs were from the 239s 1952and up. The EAB engine wasthe 239 used in the cars in 1952 and although it had the same bore and stroke as the other engines developed 110 (as opposed to 100) gross horsepower.

This is from looking at the shop manuals from the 49-51 (non supplimented) Truck Shop Manual, and the 1952 Ford Car Shop Manual. There is no mention of EAB heads in the 48-52 Ford Truck Chassis Parts Manual.

Just FYI, the 337s were listed as 8EQs

 

8ba-8ab-eab-8rt the most common heads you will see. i believe 8rt started in 49. you're engine seems to be a 239-100 hp "flattie". pumping out a whopping, (if you're lucky), 90 hp to the back wheels.

 

Thanks for the information people. Ya'll are the best.

 

Thanks for the information on the truck engine size and the horse power on it.
