u can go that route, but eventually you will have dropped enough money on new rear ends to have just bought a 9"

From what I understand, the rear housing flexes which causes the gears to meet at at off angle. Upgrading gears amplifies this. Rear diff cover is th only bandaid fix

"without a problem" means rolling starts and glamour driving.
Do you want to race it, or have a 16 second 500hp car? Just because someone HAS run it without blowing it up doesnt mean that is at all a good idea. Plenty of guys have also banged hookers raw dog without contracting AIDS. Do you want AIDS? no... so get a rear end

12 bolt or 9 inch take your pick. I would go 9 and be done with it since it will take any thing you can throw at it. Building a 10 bolt is a waste of time and money end of story.

my 2 cents, grab a spare 10 bolt so you've always got a spare axle to hand. If your building the motor first the ms3 cam etc is not going to be as bad as a 500 hp turbo car on the rear. Manuals put more strain on the rear too when the clutch is dropped espectially with tall gears 3.73 up as the pinion is really small, thus weaker.
if you want the power first build the motor and get spare 10 bolt but drive carefully, and keep saving for the 9"

Dark, if you plan on hooking at all...plan on buying alot of rears. I blew my 10 bolt apart with a girdle, went to a Strange 12 bolt, broke that too. If you don't plan on selling your car, buy a 9" and be done with it. Midwest makes a great FAB9, along with some other companies.

go with the 9 inch for sure. You won't be dissapointed.
The 9 inch housings don't have to be fabricated, but they do need cut down and you need to weld the GM ends on them. First Try Engineering did mine, I think he's doing them for around 1500-1700 now. I've had mine under the car for a year now, its held up to countless launches and 60ft times in the 1.4x range.
we started with this: a 79 ford f150 9 inch
then a couple of days of hard work later, had this:
the lightning bolt on the back is because they call my car "white lightning"
