Nice work looks good and a lot of work into that props for the good welds.

Best piece of advice I can give is keep the internal transmission temps under control. Molecular separation due to kinetic energy spikes is what tests material properties.
"But I am still worried that +400 ftlbs for 9 hours straight that its gonna eat that tranny away...."
Remember that torque is a measure of work and in this case it is not a direct measurement of energy (joule), but is related. The components inside the transmission can handle the stress of 400 ft*lbs, but as the force is applied, the kinetic energy will begin to rise (temperature) and the molecules will begin to separate. Any imperfections in the manufacture of the components will be tested if the kinetic energy is not kept in check. If you can keep the components at a constant temperature (average kinetic energy), the components won't care if you are at hour 1 or hour 9. It's the drastic rise/fall and very high temperature that will cause failure.
EVO lsd will lock harder and sooner than your old viscous coupling, please see the thread below for more info

A dog box built with the same materials is just as likely to fail due to temperature issues.
Any strength you add to the internals will give you more room for error in keeping temperature in check. It's the same concept as building a motor. Most people will never test the limits as far as force applied to their "built" motor.... They do it for the fudge factor. A forged internal motor that has a 6 knock count at 400 ft*lbs will live because of material strength. A stock motor will likely not.
Quaife center will probably cause you a catastrophic Transmission failure.
When the center diff breaks it usually takes out the transmission at the same time.
Please read regarding that as well.

I have the Weir 16 clutch upgrade, 4 Spider OEM VC center and Quaife Front.... I can let you know how that works out when the weather is better. I was a understeering pig last year with the Quaife front and open diff rear, hoppefully this will balance my car out better.Thanks man! I was totally just reading that in the lets talk diff thread...
Seems like the 4 spider with VC is the best center, the Evo8 with the 12 pack upgrade is pretty stellar for on throttle oversteer, and I'm still trying to figure out the front....

You definitaly cannot let go the gas pedal while conering with the Quaife front you will understeer like you never seen before.

Where did you get the 4" u bend? how much? I need one for my intake setup as well.
