AMC 20, 4.44 Dealer Installed Gears, factory 2 piece center section, Henri's axles....It was "built" in 1970/71...ran best of 11.40's with 8 inch slick at York US 30 in 1971.....has about 200 runs on it by the original owner with no issues. The OE has picts of the front wheels about 12" off the ground on a 7000 RPM launch....only time he said he ever did it.....but he didn't lift!!!...just carried through. The above guys are running today's technology and if building in today's world the Ford 9" or Dana 60 are the only way to go.

If you put the Amc 20 and a ford 9" side by side the amc looks like a toy....
Launched my stick car with an Amc 20, welded tubes, boxed spring perches, moser axles. I ended up twisting the spring perches and stripping off the splines on the mosers. I wouldn't waste my time with the Amc rear.... |

Anyone know the actual finished install cost of an 8.8 vs. just putting one-piece shafts into an AMC20 for say a 12-13 sec. car?
- does stock driveshaft work, i.e. just need yoke/adapter/conversion u-joint or need a longer/shorter shaft? - what is the cost of c-clip eliminators to suit drag - cost to adapt brake hoses, e-brake cables, etc. - u-bolts, shock mounting plate, etc. to suit larger diameter tube - deal with greater pinion offset - do Ford hubs have a smaller pilot diameter if using hub-centric wheels Dr.Diff cut-to-fit one-piece shaft kit for the AMC 20 is $295. Can you fit an 8.8 for less that is stronger? http://www.doctordiff.com/amc-1-piece-passenger-car-axle-pkg.html Thanks,RD. |

We ran 8 3/4 rears behind some some pretty stout big block mopars and the held up just fine..The better your suspension is set up the less strain on your posi, limited slip,twin grip will suffer

Got a Ford 9 in the Spirit from a granada (Bolt in) with a Detroit Locker, Mosers and 3.73. In the Matador I have the factory 20 only because of the 4 link suspension but it has Mosers, Auburn Pro and 3.54's w/stitch welded tubes. When I blow it up it will get a Dana 60
