Is it possible to put a 26/27 tranny and hogs head on a 24 engine? My engine is 9183221 and it has a 26/27 trans.

You'll need a four dip pan and they didn't start until late july at well over 10,xxx,xxx.

Tyrone, absolutely. the only difference besides the pedal spacing, would be no bosses on block to bolt top bosses on transmission cover to block, and better braking. My grandfather's 27 coupe had a 22 engine block for 50 years.

I didn't think about the four dip pan, but wouldn't that be only for conveniently adjusting the bearings? The block and transmission cover holes in the two pans should be the same.

Tyrone, my 26 touring has the stock tranny with a 24 engine. Even though I was under the car 30 minutes ago I didn't count the dips on the pan. Roger is probably right, he usually is.

Tyrone, trial fit the hogs head first to the block, I have had to dremel in front of the top holes to clear the block but then it will work.

You will need a four dip pan. My 26 coupe has a 1919 engine but a 26/27 transmission.

There is extra room in the rear of the pan on the four dips - you'll need it for clearance for the wide brake band. With the three dip you can also have the 26/27 trans, but only with an earlier hogshead and a narrow brake band.

The four dip is flimsier than the three dip, so without the two upper bolt connections to the block you'll really need the corner brackets Ford used as reinforcements those years.

Thanks, Roger. I had a senior moment and forgot about the need for a four dip pan to clear the wide transmission band. My grandfather's 27 had a four dip pan and I forgot about the need for clearance. Sometime in the car's life between 1927 and 1951, when he last drove it, something failed in the block, probably bearings, he went to a wrecking yard and bought a used 22 short block and then assembled the engine with all the original 27 engine and transmission parts, except the 27 block.

Long ago I had a T that had a wide drum trans in a three dip pan. You have to use the narrow drum hogshead and band, using only the front portion of the brake drum. The back of the drum was real close to the pan, but it worked.

Don't forget the two front floor boards will be different, as will the metal pedal surround plates.

This engine was in a car I bought years ago and I'm just now taking apart. It does have the four dip pan, the newer hogshead and the wide brake drum. But the engine number indicates a 23-24? I was just wondering what the devil I should title it as. Its becoming a speedster.

You can use your a three dip pan if you use a narrow band on the brake. I ran a 17 engine like that for several years.

Tyrone, my '25 coupe has a late transmission. The four dip pan was used along with the late hogshead. The pedals were swapped out for the early ones so the floor boards didn't have to be modified. Works out great. Dave

Tyrone T,
I hear that Kansas is easier to get along with, but I have never tried them. In Califunny, you call that a roadster. They have a code for that, and don't care about the difference.

As far as mixing transmissions, and pans, and hogsheads, and drums, and clutches and?, and?, and? and?, and? There are so many combinations, so many that work fine, and a few that DO NOT! Like putting a late hogshead over an earlier transmission. The spacing is wrong and the earlier transmission drum is not large enough to accept the offset spacing.
Drive carefully, and enjoy, W2
