8ba into a 34

[oldford2]

Here is the question:

Will an 8ba with a truck bell and starter plate bolt up to a 34 ford sedan model b transmission? If not, what next to make it work?

Thanks
John

You would need a 32-39 pass or 40-51 floor shift trans case and change out the 4cyl gears. Also a 33-34 v8 rear trans mount is required but it is possible to reverse the 4 cyl mount. If the 34 still has the 4cyl rear end, the tork/drive shaft is shorter and will position the engine too far back into the firewall. You would have to use the 33-34 V8 driveshaft/tork tube to get the original v8 motor position.

Barn Junk, Thanks. Sounds like it is getting complicated.

We are just trying to find out if the original transmission/torque tube can be left in place and the 8ba can somehow be fitted in. This must have been done. Maybe not. Thanks

Barn junk pretty much has it. The 4-bangers were longer than the V8 so had to have shorter drive. The 8BA still has the bolt holes down front for the early style front engine mounts but some folks use the 8RT truck type pumps and make new front engine mounts. If a guy can find a V8 rear axle for the 32 thru 34 with the torque tube & shaft, that would make life a little easier. You would need a V8 radiator too.

I believe in addition to using either truck or Mercury water pumps you will need those "U" shaped spacers that were originally used under the foot of the water pumps on the Mercury. Speedway and Drake sell those spacers if you can't find an original set. I believe without those spacers the crankshaft pulley will hit the front cross member.

One small plus. This engine has truck pumps.

Getting some good input on this project. Anyone have a picture of a V-8 in a 34 model B? Thanks

you'll be hard pressed to cram a 8ba in a 34 pass body,59 ab is a pretty much bolt in,

[oldford2]

34 Coupe. Thanks for your input. You indicate a 59 ab is a bolt in but an 8ba is a cram. Does that mean the 59ab engine will bolt to the model B transmission? Where is the interference on the 8ba to make it a "cram"? I could always "convert" the 8ba into a 59-ab by: using a 59 cam and timing gears, crab distributor, fan assembly, 59 heads, etc. Any pictures?
Thanks

John,

None of the V8's will bolt to a Model B transmission. The starter on the Model B was on the upper left looking forward in the car like a Model A. The starter on the V8 is on the lower right.

Although I am not 100% positive I think you meant to say "rear axle for a '33-'34".

Do a search as Walt & Ol Ron have the answers.
59AB & 8BA parts interchange

The 32 thru 34 "V8" rear axles are all the same but a person would have to find a 33/34 V8 torque tube & driveshaft to fit it in a 34. It might be easier to find a later rear axle and shorten the torque tube plus the later axles are a bit heavier duty. Some of these parts are getting harder to find now days. If a person can scrounge up the parts, it could be closer to being a bolt in.

[oldford2]

This 34 model B is not a 4 banger. V8

[rotorwrench]

The model Bs were all 4 cylinder cars that succeded the model A. The model 40 was a V8 car for 33/34. The model 18 was the V8 car for 1932.

Banger is only a slang term that can be used for any number of cylinder arrangements but it is mostly used with the 4-cylinder cars of the Ford model T through B production.

Hi all; On this 8ba into a 33/34, the laid 'back' radiator will be a problem. I have seen it done, BUT the eng had a 59ab type front put on it. Newc

I was including the torque tube and drive shaft (and maybe a few other "restorer" type parts but I am not sure) as part of the rear axle when I made my statement. Also only the very late '32 rear ends (excepting the torque tube and drive shaft) are the same as '33-'34. For most of '32 the B and V8 used the same rear ends.

No, it bolts up to a 34 V8 trans, or better yet, a '39-type' trans.
Other posts here are pertinent. And, the comment to contact Walt & Ron is pertinent. Also, Richard, EV8G, who used to be a regular here, is also an expert on putting late engines in a 34. You didn't ask, but you will need to consider the problems 'up front' - like extra length, too many crank pulleys, gen & fan, etc (and the mounts, already mentioned).
(Another consideration... You will probably want to select a bolt-in combination of flywheel, starter, and clutch. The experts may steer you away from 8ba parts, and more towards 59A, or 9-inch.)

(I've seen some real butcher-jobs, relating to the 'up-front' issues. Even a picture posted here by someone that used the Merc water pumps, and raised the engine up way high, for the front to clear the 34 front crossmember. It looked like a real mess in the pictures. My point is, you can do almost anything you want, but some solutions look a little better than others.)

Bob H,
This is a 34 V8.

Sorry.... I thought it was/is a model b. If it's already a V8, much of the above posts probably mean nothing. You should already have a V8 rear end, trans, and trans mount.
