i think if I do the rear end, it will be a 12 bolt or a 9" I've been told not to waste my money in a 10 bolt so only time will tell, but Im sure I will need to do something soon. I am putting the car on the bottle so Im sure it will be a 10 second car which NHRA requires these. Who knows maybe ill have enough money by then to invest in a good rearend.

A built 8.5 ten bolt is a good rear end. Just don't waste money on the 7.5 10 bolt. If you already have the 8.5 10 bolt, invest in some good axles, and the c clip eliminators and you should be good to go. Do you know if you have the 7.5 or the 8.5?
LOL havent even gone to the garage where its at, its to cold to be out in this stuff. It was -22 this morning and well tonight its alittle better at -15 so Ill wait till sunday when we get our heat wave of 28 degrees.TOMS78BU said:
so where can i find info to swapping in a 12 bolt or 9"?
maybe i can find a 8.5" for cheap some time soon.
I HAVE A TRANS BREAK ON MY CAR .. HAS A REINFORCED 12 BOLT WITH MOSER AXLES AND C CLIP ELIMINATORS
LIKE PEOPLE HAVE SAID BEFORE THEY ARE HARD ON THE DRIVETRAIN
I WOULD NOT RUN ANYTHING SMALLER THEN A 12 BOLT WITH A TRANSBREAK
AND I WOULD NEVER RUN STOCK AXLES
NOT TO SAY YOU CAN'T RUN STOCK OR 10 BOLTS BUT I LIKE TO LIVE ON THE SAFE SIDE

We built a 7.5 for my brother's Malibu, its a 13-1 comp, six inch rod 350, with -10 heads, 350TH with a race/good stall(not a boss hog street converter). 4.10's in a 7.5, Moser 28 spline axles (same as those in the GN/8.5) and a used posi unit out of a '93 up F body. It made 252 passes into the low 11's, maybe one 10.90 pass with pepper spray (thats when the track said: No more until it has a roll cage!) Its got 28 x 10.50 slicks and he does hard core burnouts. Yes, it did break, but, thats how long it took abuse.
You do not have to remove the rear-end to add the c-clip elimiators, they are just a press on bearing that bolts to the end of the housing to secure the axle in the event of an axle failure. Its a saftey deal, no matter who makes the axle. The weak part of the 7.5 is the spiders and the ends of the axle where they tapered down. Its not a ring or pinion failure.
The '98-02 LS powered F-body cars have an even stronger carrier, with four pinions for the posi/spiders. The carriers bolt together, no big window that you slide the clutch stacks through.
What transmission are you going to add the brake to? Or, don't go with a brake unless you have a 400TH or lots of money, building a TH350 to take that abuse is expensive, not just the hardened sprag race (they give up after about two good, slick launches) like a stronger direct drum, heavy input shaft.
