free ford nine inch rear

[jar1292]

hi guys my question is whats the advantages or disadvantages to a ford nine inch rear end? I have a guy tell me yesterday that if i want it to come get it its just taking up space in his shop. I dont know the condition of it though. my 70 has the 8 3/4 under it now. how hard is it to convert and what douse it change for measurements im looking at around 650hp when finished so i think i need to duild up the back end now while its still on stands. is this a wise move or am i lookin fr a bad time?

well if you get the ford 9" you'll assume the following

CONS:
- Width will need to be modified (most likely not correct currently)
- Ford brakes in the rear
- Universal Joint Change
- New Spring Perches

PROS:
- Stronger than the 8.75"
- Greater Gear Selection

My opinion is to just keep the 8.75...      I would definately snag it if it if free though

 8 3/4 is a great rearend. If you had a 8 1/4 I would be worried and would want the ford 9 inch.

If I was offered a free Ford 9 inch, I'd bring it home and put it on Craigslist or ebay for $$ or trade for 8-3/4 or D60.
Is the 9 out of a car or truck?

Another pro and con;
Pro- huge aftermarket support
Con- robs more horsepower than the Mopar 8.75 (higher frictional loss because of the way the pinion meets the ring gear, a minor issue but an issue nonetheless)

[Cooter]

Pro....................About a 1/4" difference (1/8th on each side of the ring gear)..



Cons..........It's a damn Ford rearend and eveybody and their brother does it...

True, Cooter....I did it...and it was a big mistake!!!  Put a Ford rear end under a Mopar....and KABOOM!!!  Broken rear end beyond repair.....just my
