Would a late 25 hogs head have the ears to bolt to the engine block and still have the small pedals or was the block changed prior to the hogs head being changed? I have a late model year 25 block without a hogs head and need to know which style to look for.
Does the block have the threaded bosses on the back ? that will tell you which hogshead to use.
Yes, the block has threaded holes but I was unsure if the changes to the block came before the updated hogs head or if there was a hogs head with ears to bolt to the block in the earlier narrow band/pedal configuration.
Also, you need to get the correct hogs head to match the brake drum. The narrow brake band needs the correct hogs head to match. The engagement part is located further to the rear on the 26/27 style hogs head and does not line up with the earlier style narrow brake drum.
The parts books only list the new cover, for the Improved Car wide brake drum trans.
Craig, Ford switched over to the improved style at #12,218,728 july 27, 1925. After that all engines were 1926 style with wide pedals, wider brake band and the hogshead bolted to the block.
In the weeks before the change some cars may have had the wide pedals but the old style hogshead indicated by the fordor seen in this thread: http://www.mtfca.com/discus/messages/257047/285201.html?1337287016
The straps from the hogshead/engine bolts down to the pan arm bolts weren't introduced until november 1925, but all cars that can use them would benefit from straps there, they may reduce the risk for fatigue and breaking pan arms
The hogs head should match the TRANSMISION brake drum.

I tried to install a wide brake pedal in my pre 26-27 hogs head, it has different bends and hits the boss for the low pedal. Even with some grinding on the back side I could not get enough play to fully engage the brake band. The 25 and earlier pedal has a curve that goes to the rear in the lower area to clear the middle boss. The 26-27 is straight because the center of the brake was moved back.
