Bill, Thanks for all the good info. I agree a factory setup would be the best. The 4.27 is not all that bad if you stay under 55. It sure is nice driving around town or hills. Hardly ever need to use first.

I guess I should clarify my earlier statement about Ford using 3.89 as "the standard ratio in OD equipped vehicles". This statement applies to the F-1/F-100 series of trucks only. I don't believe that Ford ever equipped any of the F-2/F250 trucks with OD's. I have had a couple of trucks with factory OD's, the last one being a '59 F-100, big window Custom Cab, 292 V8, w/PS, PB, radio and fresh air heater. The truck had a style-side 6' box. The truck was not really a EFV8, however is was still from the '50's, it was a great truck. I sold the truck about five years ago because a guy offered me a lot of money for the truck. I still have a '59 F-100 V8 4x4. It is also a big win custom cab with a lot of factory accessories.

My late father-in-law had an F-2 with a three speed column shift that he used to haul heavy cream cans for his business. It had a high ratio rear end to give it enough power to handle the load, but was limited to about 50 mph in high gear. He had ordered it that way to get a full synchro transmission, as he hated the 4 speed in his other trucks. I haven't seen a four speed with OD in light trucks. Most had a "granny gear" low gear to haul big loads in hilly territory.

Clark had two 5 spd transmissions that were offered starting sometime in the mid 1950's through the early '70's. One of the Clark 5 spd's was direct in 5th year. The other Clark 5 spd was an OD in 5th gear. This Clark trans is usually found in school bus and ambulance chassis', F-3/F-5, F-350/F-500, GM C-30/C-50. I read an article in 4x4 Off Road about this trans about ten years ago. The article was about serious off roaders that were having trouble with their newer aluminum cased 4 spd's that were coming apart under hard off road use. The old T-98/T-18 rock crusher, granny geared transmissions were being adapted into a lot of the off road trucks, the one disadvantage was slow hiway speeds. The Clark 5 spd solves this problem because of the granny low gear and an OD. Of course because of the age, the OD Clark's are hard to find, fortunately I saved the article so every time I run into an old Clark 5 spd I can look up the case numbers. Many years ago I purchased an old Ford farm hand... For you city boys, the farm hand was a truck that had been cut down, removing the body and turning the controls around so the truck was operated backwards, the steering axle to the rear. A cable or hydraulic operated set of forks were mounted on the truck to pick up large piles of hay. The farm hand I purchased turned out to be an old school bus... you guessed it... the tranny was a Clark 5 spd OD.. I have been thinking about putting the Clark in my '59 F-100 4 x 4.
