Would any of the three(light, medium, and heavy duty) 5-spd OD(not direct drive) trans from the 1956 model year--once again only in the larger trucks--fit physically into an F-100? Is there a chance they'd bolt up to the 223 I-6, or the 272?
I'd love to have one because their 2nd gears are low enough to act as a 1st, and since they are synchronized, it would not only make for easier downshifts to "1st(2nd), but would also help cruising on the highway with the OD 5th gear.
I think the 5-spds only came hooked up to the 302 or 332 in '56 though.......
Will this five speed fit a 54 f600 with a 239 yblock? are the bell housings the same?
I have the bellhousing for the y block ford to use this 5sp OD transmission including the flywheel, disc, pressure plate and clutch fork. I also still have the trany if anyone is interested. Ford used the y block with the parts to use this transmission in the 700 for a few years and anyother of their HD tranys of that era.
Oh yea I have a truck just waiting for an 5 OD allthough being non sync
I dont care. These are ment for F7 & 8s. so anybody thinking about
F6 & under there will be driveshaft issues and pilot bearing issues, and
I dont think smaller Y blocks or something has a big enough crank bore
for the big roller bearing pilot I think the input shaft is around .750 or
larger and memory thinks the U joints were spicer 500X way bigger than
F6- F600s. So I will be interested. Sam & Sons
Should be able to have a pilot bushing machined to fit if needed and any drive line company can put a drive shaft together with the needed ends. The Y blocks in the 54 F700 used a different pilot bearing then the larger truck engines, don't know the difference but shows a different part number.
I dont know if you guys are familiar with the 60s internationals, but they used 3 and 4 speed trans that should bolt right up to a ford. I have a 63 c1300 with a straight 6 and it has 4.88s and is SLOW. It has a three speed and a five speed with overdrive would be sweet for that truck. and if it did not bolt up as planned then it should go in my 54.
Just wondering if you ever attempted that swap? I have a line on a 5 speed from a 68 IH for my 53 F350 and was just going through the motions to see if it was similar? Any way to reference it?
I would measure the input shafts before commiting to buying. (T34)
Its on the bench so I can take some measurements,anybody have the numbers on a tock 4 speed anywhere to compare? I am blown away by the knowledge on this site so I figure it never hurts to ask. It would be good to know if these are an option for our trucks.
What I know so far is that in an IH,you have to swap the flywheel and use a different bellhousing than you do with the 4 speed when converting. They are also available in a 5 speed direct and a 5 speed over.

Even in an IH, the 4sp. and 5sp. use different bellhousings. The flywheel is huge, will dang near knock you out if ya ain't careful....don't ask how I know, lol. Anyway, a smaller Ford flywheel will be needed to fit a Ford bellhousing. (and starter)
It would be an interesting swap to see.... won't be easy, I have a feeling.
The rest are just average.
