The 271 HP HiPo Mustangs and Fairlanes had the 9 inch
The 3 old Ford parts catalogs PLUS the Hollanders I have ... all say no original factory Ford gears lower than a 3.80 for a 8 inch. I myself have pulled close to 75 to 100 8 inch Ford rears ... and never ever saw a 3.80
When dealing with the 8 inch Ford
3.40 and 3.55 are somewhat easy to find.
3.50 is available every now and then ...
Posi rears are very scare ...
Most are 2.79

|onebadmerc||I knew a guy way back when who owned a 1967 CS HP289 Mustang and it only had a 8" with 4.10 or 4.11 rearend ratio. He said he bought it that way from the factory. I didn't think Ford put the 9" behind any of the Non-Shelby Mustangs or Fairlanes until they stepped up to the 390 in 66-67. I know the Shelby Mustangs had a 9" but I don't think any of the plain jane HP289's did. Somebody who is alittle more knowlegeable about Fords would know, maybe they will let you know.|

By all reports ... the HP Mustangs came with a 9 inch ...
Fomoco parts catalogs from back then do not show a ratio of more than 3.80 for the 8 inch series ...
Whenever the Horsepower got halfway serious ... Ford went to the 9 inch. Even in the Fairlanes, Comets, Cougars and Mustangs ... because of warranty concerns.

|onebadmerc||Ford did put a 4.10 or 4.11 (not sure of the ratio) in a 8" under the HP289 Mustangs but good luck at finding one. You will have to go aftermarket if you want that ratio in the Ford 8" rearend.|

Why 8" and not 9"? You are far more likely to find what you need in a 9" than an 8".

Sorry I didnot say they did. I say I an looking for a Ford 8" with 4:11 gears in it. I know they are out there I just don't want to pay 995.00 for one. Thanks

Hotrodders.com has a wanted classified ad section ... try it
and by the way ... Ford did not make any 4.11 rear gears for a 8 inch Ford ... if you find some ... they will be aftermarket
