have a chance to buy a Ford 9" with disk brakes. I and who I can buy it from have no idea what it's from. All I know is it's 2 inches wider than a 12 bolt I have. The 12 bolt I have has Milodon caps and a TA girdle cover but the axles are twisted so bad the tires will wobble if used. I wrecked them with radials and the old 455 I had. :Brow: The new BBB will make in excess of 600hp. Lookin for deep in the 10's. Should I buy this Ford 9" for cheap and beef it up with a Detoit Locker or stick with the 12 bolt and buy new axles? Any feedback is greatly appreciated. Ray
But 2 tenths slower. I vote for the 12 bolt. Stock Ford cases are junk also. Is this a factory Lincoln disc rear? It's not an Olds 12 bolt in your car now is it? Get a set of 33 spline axles and a spool. Is this a dragcar? I have run 9" rears in the past, there great to work on but rob power. Nothing is strong in stock form and it will cost twice as much to build a Ford.
That's impressive. Nice launch with the 68 Jeff. I'll have a roll cage to. It's in the works. I figure on having the pressed in axle tubes welded in if I use my 12 bolt rearend. Are they welded on the 12 bolt rear you're running? Also what kind of bearings for the axles? Ray
The 68 "black car" has the welded housing ends on it and the 69 Champagne car with 68 grille "now has 69 grille" has Mark Williams c-clip elims.
I toss my opinion in here. you know what they are like so take it for that. People say are slower (never heard as much as 2 tenths though)but when it was changed in my old blue car there was little to no measurable change. I do agree with putting in a good center section stock are pretty weak. not trying to do a sell job here but we have new 9+ units for 250.00. Second I always carry a second center section with a different gear but close to what I'm running with me I can change the gear by myself in 45 minutes puttsing along. I have seen more than one of my competitors not make the next round due to breakage when I could have made a gear swap. If it has ford disc on it they weigh about 5 million pounds so there is no advantage there. The 12 bolt would be better for that. I put GM metric disc brakes on the back of my race car they work extremely well for the price they will lock the tires if pushed and the car stop very good and that is important to me :laugh: . There are going to be good points both ways but for my money and being able to make the next round I like the ford. I know a couple guys that were 12 bolt guy's till they cleaned the teeth on a ring gear at the worst moment then I offered my spare center section but it wouldn't fit for some reason. :error:
9" 9" is a pretty good choice. It works for me. I run a aluminum center section that helps lighten things up some.
If you go with a 12 bolt do yourself a favor and have bolt in axle ends welded on the housing. Does not realy cost any more than a c clip eliminator kit.
Ford 9 inch from Lincoln Versailles Ray The Lincoln Versailles ( or however you spell it) is 52" wide at the bearing flanges and it was the same width as my Buick Regal. It fit like a glove once I got the brackets attached. Something to be said about having a center section rather than a rear load like the 12 bolt if you have to change gears sets. It is heavy and you would have to have a after market nodular iron or Aluminum center section and at least 33 spline axles to hold 600 HP with slicks. I twisted my Moser 28 splines and broke the center section with 500 HP w/10.5 slicks. Fabricating the brackets will not be cheap unless you can build your own trailing arm brackets. I built the jigs and did my own machine work and it took a while to get it done and there are no brackets available to just weld on. The 2 tenth is a bit steep for ET lose using the 9". It doesn't weigh 200 lbs more than a 12 bolt. 100 lbs per 1 tenth of ET I understand is the formula for weight to ET ratio. I would estimate it weighs a good 60 or 70lbs more than the 12 bolt. Good luck! Weekender
If you need something from a wider car, the Mark IV and Mark V had 4 wheel discs with the 9", and the Continental had 4 wheel discs with the 9" as an option. Discs are about 11" on the big Lincolns.
I don't think weight is the big issue. The pinion to ring interface is inefficient on the 9" and wastes something like 4% power.
My opinion... Im think Im going to put this in my 69. I priced out a Moser or Currie built 12 bolts and the ford 9" is only a couple hundred more but the strenght is better. https://www.cachassisworks.com/iwwidb.pvx?;multi_item_submit I know its not a "GM" but I dont want to blow up my stock 8.2, and need to upgrade. So Im going to spend the money anyway, so... what is the right answer??? Strength and vertsitility... Im going with Alstons FAB9. Michael
