23 tranny on a 26 block?

Post by joness » Thu Jun 01, 2023 4:44 pm

I know the later trannies and hogshead don't work on an earlier block but would a 23 tranny and hogshead bolt up to a 26 block? thank you.

Hi Stephen, welcome to the forum (I see this is your first post).

Yes, I believe it will.

Kind regards

thank you, yes first post. I have a lot of old fords (58 Skyliner, 62 Ranchero, 65 Mustang 2+2, And a Tiger). Have had my T (nice rolling roadster and parts) for 25 years. Was in a real barn on a real farm, Body really really nice. Just getting into it now and love it. Have a really nice 26 long block and a really nice tranny from a 23. If they mate up I'll be in good shape.

any transmission will mate to any block

what must match is the style of hogs head to the type of transmission, because earlier transmissions have a narrow(er) brake band and that requires the brake pedal to be lined up in the right place on the drum (thus matching the hogs head style to the correct transmission)

you will possibly want to marry up a 3 dip pan with things to provide support lost from not having a hogs head that bolts to the back of the block, or plan on plenty of accessory stiffening and perhaps a tranny sling added to avoid possible broken crank

It wont bolt up to the "block" The earlier H/H has no mounting tabs for the block like the late one has.
However, you can use an early H/H & transmission with a late block.

Just to add a little to this. You can't use a late H/H with a early trans as the short brake band will not line up with the short drum. You can use
the early H/H on a late pan & trans but must use the narrow band. The late H/H will not fit the early engine without a late pan & trans and
you will need to remove part of the ears to get it to not collide with the early block. The thought that all modelT parts interchange is akin to
all skinny block chevies are the same.

Just want to clarify because I’m in a similar situation. Is it fine if I have a 26-27 pan with a 23 block and tranny with a 1919-1925 hogs head or will I have to make some modifications when I put on the 19-25 Hogshead?

You should be fine.

Jacob

it will be just fine

the issue is that the 4 dip pan is more flexible than the 3 dip, and therefore FORD reinforced things by making the hogs head so that it could bolt to the back of the engine and stiffen things up

So, when I say it will be just fine, that means everything will fit. It will still be prudent to look for a transmission belly sling (accessory) to support things since the hogs head won't.

I have built just such a combo for my runabout that I intend to tour. I wanted the 4 dip pan so as to have easier access to the 4th rod incase things go wrong on tour.

Its fine & quite commonly done.
There is a bit of weakness in a 4 dip pan compared to a 3 dip in the area between the engine & transmission. Definitely use the pan stiffener brackets in those corners. It has been suggested that adding an extra support under the transmission will prevent any sagging.
I have not added this extra support & not had an issue.(that I am aware of) But its worth consideration.

As Scott and others might have said; ANY T transmission will bolt to, and work with, ANY year block. I don't know who told you, or where you got the idea, that 26-27 transmission didn't work well with an earlier block. They work just as well as a pre 26 transmission and cover on a 26-27 block. The difference for both is the same. If you have a late block and an early hogshead, you can't secure the hogshead to the block using the two tapped holes. If you have an early block and a 26-27 hoghead, you can't secure the hogshead to the rear of the block, because the tapped holes aren't there. For 15 years, my Grandfather's 27 coupe had a 22 block and a 27 transmission and hogshead, I only changed the engine to replace with the correct block.

Thanks for clarifying. I’m getting everything ready to put on the correct Hogshead for my transmission soon. I have a Warford and my truck so it has the crossmember that holds the driveshaft, transmission, and aux transmission up and should helps with supporting the 4 dip pan.

At one time there was a solution available to ease the concerns about the 4 dip pan flex and those people who have installed it have had great success. Unfortunately it is no longer available. I’m referring to the “floating transmission shaft”. It removed the strain load from the crankshaft. But hey cranks are cheap.

Is there a reason the floating shaft went away? Was it simply a cost issue?

Trying to remember did the later pans have more space on the bottom for the brake band? In general keep period hh with same period trans.

Thanks, Dan... I remember these floating shafts, and I've never heard of anyone who used one complaining.
