v6 Rear end build or sawp?

[Camaroe3]

Well the car was a stock 3.4l V6 car. now a lt1 is under the hood. I no i need to up grade the rear in some way.

It is time to work on the rear end. So do i just build up the stock durm 7.5 or buy a used z28 rear with disk?

ALso did gm offer a 7.5 in the v6 car and a 8.5 posi in the v8 car?

The Y87 Cars had an upgraded rear axle but if I were you I would just buy a used one off a Z28 or TA. Depending on what happens this week, I might have one you could buy. But right now that is a last resort.

well if you turbo project goes through you'll want a moser 12 bolt or 9" to handle that power.

7.5 in all fourth gen fbody cars.

if you're going to spend money on a rear end go with one of those choices, or an s60

and they are all junk!

...the car/engine bay picture in your sig is actually finished, it's someone who ForceFed98 knows on ls1tech....

Youll def wanna go atleast 12 bolt on this one, if not stronger. the 10 bolt in the birds stock are worthless for anything with drag radials on it, lol.

[Derek]

just by reading your sig... Goal 750rwhp+
dont even think about having a 10 bolt...

ever said that was my set up. just that is the same set up i am going with. frount mount s475 .


Also i would liketo bolt in a for 9 inch but at this point i no that i am not going to be making much power. maybe 550rwhp. at best. I still have a ton of work to do and i want to get the thing runing. i have seen 9 inch kits for my car but they are like 2k .

and what is a s60?

[Thedon619]

the s60 is a dana axle i belvie, not positive tho, but a good dana rear end is bulletproof.

550 rwhp is too much for a 10 bolt assuming you have traction.

Im worried abotu breaking mine with no more than 300 rwhp

So you are telling me that. i i werh to buy richmound gears and pinon kit with some moser axles . that the rear 10bolt 7.5 would not hold 750rwhp?

plan B: 9inch ford

I would like to use a 9inch ford. I have to buy a custom driveshaft so y not?

1.
Well I was thinking a used 9inch ford . rebuild it and have it cut down to size.

2. buy a new housing , and tub kit. have it fabed to fit my car. then buy new axles and a used center section.

3. company with a prefad housing?

GM gears are the strongest. Getting richmond gears would be a downgrade if it changed strength at all.

your best bet is to go with a 9" ford made for an f-body. The torque arm mount is not something that can be "fabbed" ...believe me ive looked into it, not happening.

[DETROITMUSCLE]

Yep no 10 bolt will hold that much power.....ever. Hell they have a hard time holding 400rwhp in a manual car. As for rear ends look at spending at least $2200 but its an absolute must for that kind of power. Drive-line solutions has exactly what your looking for.
