I realize now that my 9 bolt 3.27 set-up is going to be marginal once I move up over 400 torque. So if one of you spots a deal on an actual 'STRANGE' or something of that nature, could you contact me??? I'd definitely give out a finder's fee. Nitro

 

Call it wishful thinking but I bet that 9 bolt rear will hold up better than you think. I've hear stories...

Just sayin'...

Other names to consider maybe? Dana, Moser?

 

i whouldnt worry about it till u need aftermarket axles and ure dippin 11.50 or better im still on my 10 bolt good for 1.6 60 ft and i have my other buddy 10 bolt no girdle goin mid 1.45 60ft and the 9 bolt parts are harder to find but if its together holdin up i whouldnt sweat it same thing in my buddies ls1 6 speed he was worried about the stupid rear end broke the motor instead of rear end **** happens track only sweats u on axles when ure dippin 10.s when they ask my buddy if it has axles we say hell yaa it has axles most cars that go have axles if not they whouldnt be goin to far

 

Long live my ten bolt!

 

this is what u need right here

 

Now I damn sure liked THAT pic! The rear end shop owner told me to stay away from anything 'Auburn'; allegedly stuff has greatly improved since that set up was popular.
I know absolutly zip about rear ends. Having the differential shop and the transmission shop shake their heads as they walked away gave me a scare! I thought I had done plenty of 'SEARCH' on rear ends for our cars and the Borg Warner kept coming up as having a much longer longevity life than the common 10 bolt. The rear end shop owner walked me over to his supply of american gear sets and showed me that Ford & Dodge only used our size of gears on just their 6 cylinder or 4 cylinder drivetrains.

I did get enough information from the tranny shop who did my 'alleged' stage 3 build and figured out they took lots of shortcuts and used parts that are usually installed on Stage 1 & 2 builds. I spent most of Friday afternoon documenting all my notes and the conversations I had with them when I asked for my estimate. Since I've put less than 500 miles on the new 700R4 in 6 months due to part failures; I want to be able to extend my one year warrenty period to start fresh when they've finally got it running correctly. I even phoned the Converter manufacturer and asked what their standard part number for a 2200 stall, 400+ torque engine and found out that the one I got billed for is just the normal factory 1800-rpm stall without anti-ballooning or brazing.

I made sure that it's documented in writting that I plan on dragracing this puppy, so hopefully once the new engine gets installed I can go see if I can blow up the tranny and force the issue.... Nitro

 

I've heard nothing but good about our 9 bolt rears. I'll wait until I need to rebuild or replace it. My dream is to be 400BHP and wiegh less than 3000 lbs.
