Well, you really need to learn the language so I'll try and help.
Ford 9" = a Ford rear end that has a 9" diameter ring gear. Hasn't been used in factory production in many years, but is readily available on the aftermarket. You'll also see reference to Ford's 8.8". Same deal, ring gear diamter. Not as stout as the 9", but not bad either. The 9" is the holy grail for brick shithouse tough. All the references to Moser 9, Strange 9 etc. are aftermarket copies of Ford's design. The term Fab 9 will come up also. This is a fabricated housing that uses a 9" center section, which is called a carrier.
Dana 60 = Chrysler rear end, but not made by them. Again, not from the factory in many years. Available on the aftermarket, you'll see the S-60 mentioned quite often. Good stout piece, but not quite as stout as the 9".
12 Bolt = GM's heavy duty, not available from the factory for many years. 12 bolt refers to how many bolts hold the back cover on. Available from the aftermarket. Not as strong as the 1st two, but plenty for a street only car. If you're running an automatic, good on the track too. High horsepower and a stick or transbrake, and you'll it destroy eventually.
Your stock rear end = GM 10 bolt. Again, the number of bolts holding the cover on. Looser piece, even when new. Still in production, still a looser piece.
When you go to the 150 shot, you'll want the 9".

I could be wrong, but I thought the Dana S60 had a bigger ring gear than the Ford 9". I believe it is 9.75" (9 3/4"). I also believe it is more stout and has less loss that a 9" due to the alignment.
A benefit of the 9" is that the pumpkin is fairly quick to swap out and can be set up on a bench. I've heard of some people carrying a different "pumpkin" for the track and for the street.

With the torque arm and DS it doesn't sound too bad. You might check with some of the site sponsors here before you drop any money though. See the current thread about Midwest Chassis and Performance.

Here's a similar thread on another site:
http://www.ls1lt1.com/forum/showthread.php?t=20642
Here's a link the PHR magazine:
http://www.popularhotrodding.com/tec...all/index.html
and snips from the 1st 2 paragraphs:
With all due respect to the competent GM 12-bolt and legendary Ford 9-inch, Chrysler's Dana 60 is the mother of all rearends. This absurdly robust driveline specimen was originally designed for heavy-duty military vehicles during World War II, and was adapted for street combat in the '60s by Chrysler to endure the fury unleashed by its Hemi- and 440-powered muscle cars. We're currently busy putting the finishing touches on a built 455 big-block for our '65 Olds Cutlass project car, but its projected 500 hp is respectable rather than incredible. As such, our original plans called for replacing the factory 10-bolt rearend with a 12-bolt, but when Strange informed us that it offers a big-inch Dana 60 for GM A-bodies, we were more than intrigued.
Without question, nothing embodies overkill more than installing a Dana 60 in a 500hp street machine. Nonetheless, its benefits over both a 12-bolt and 9-inch made the decision a no-brainer. What makes the Dana 60 so good are its massive 9.75-inch ring gear, 35-spline axles, heavy-duty cast centersection, and 3.125-inch diameter axle tubes. In comparison, factory GM 12-bolts incorporate 8.875-inch ring gears, 30-spline axles, and 3-inch axle tubes. Stock Ford 9-inch rearends, on the other hand, make do with 9-inch ring gears, 28- or 31-spline axles, and 3-inch axle tubes. Granted, bigger aftermarket axles can be easily swapped into the 12-bolt and 9-inch, but bigger ring gears cannot.
No, it is the ring gear. But it's a common misconception.
There were actually some 12 bolts with 10 cover bolts on some 60's GM cars.
The truth is, any one of these rears will work for you. Talk to a sponsor and see what is best for you and your budget.
