Overdrive Clark Five Speed Information Compiliation
I have been searching for a good overdrive swap for my '66. I have decided that an overdrive Clark from behind an FT/Y-block would be the best.
The transmissions that I have found that might work work are as follows:
251VO
264VO
280VO
From my research (and others) I have found that the 264 and 280 are synchronized while the 251 is constant mesh. Is this correct?
I have also read about a few overdrives in the 300 series, but those are larger and unnecessary.
I have read of some mention of the following:
264VOHD
280VOHD
282VO
285VO
Where any of these installed behind FT's/Y-blocks?
The Clark numbering system had the model (280VO) followed by 2 numbers like this: 280VO-21.
Can anybody (tripleframe and NumberDummy) finish the model numbers of the aforementioned transmissions that would be behind a Ford motor. It would also be very helpful if someone could supply the the input shaft diameter and spline count.
Maybe this will save someone a bit of trouble down the road.

Wow. How many books do you have? That is interesting stuff.
I found a 280 VO 21 for sale on the internet. The only thing it says about it is:
FORD APP
FRT RET 230211
What would this have come in? What motor could it have been behind?
I appreciate your research very much.

These transmissions were shelf items available to all truck manufactures. Just like the New Process 435, there are variations to fit either GM , Ford or Dodge etc. THe safest way is to locate a period Ford with this transmission bellhousing and engine still intact.

Do you have any info on the 2 numbers in the suffix? What numbers were for which manufacturer and/or motor?

I have seen gear vendors overdrive units sell for around 1200.00 or less. Why not just install one of them? Much better unit you will never break and you will get a 22% O.D.

Sounds like an awful lot of work searching and installing a trans that only has a input tq rating of between 260-325 lb ft. That about puts out any decent Ford V-8 or 300 6 cyl.

I have researched a lot of options for my '66 4X4. I have 5" to work with before my center drive line gets too short. The gear vendors adds 13". The ranger overdrive box adds 7 1/2". The 280V Clark fits. I have heard it rumored that the 280VO shares the same case as the 280V.
The NV4500 also fits, but I can't use advance adapters adapter plate because my bellhousing/current input shaft are longer than the later NP435 bell housing/input shaft. I would have weld my bellhousing up, drill and tap it. One of the bolt holes would be off the flat mounting surface so it would have to be built up. If all else fails, that is what I will have to do.
