1FZ trans swaps 6R80 10R80 and more

So because the custom intermediate shaft is made for just under 600 foot lbs of torque, does that mean the full potential of the 8HP75 can't be utilized in an all-wheel drive configuration? I was hoping avoid a part-time changover.
I'm getting an engine built right now that will be fully forged with a 5.0 liter BC stroker crank.
I will turbo my 1997 U.S. spec LC and will have a full standalone ECU
I fully expect I will be able to make north of 600 foot lbs when I turn the boost up near 20 psi with a G40-900 or G40-1200 sized turbo
Any advice for how to handle this in an AWD configuration?
If I do have to go part-time, is the transfer case weakness taken out of the equation?
I don't want to go manual; would rather keep it automatic.

I build 80 series with Cummins power theoretically in excess of 800 lb/ft. I always use the HF2AV in AWD configuration.

It's difficult to put 600+ ft/lbs to the ground with an 80 series. These cruisers are so light they either accelerate or they lose traction.

On my waterbrake dyno I can force and measure up to a 1200 ft/lb load on an engine. An engine that can hold 800 ft/lbs at 1600 rpm can NEVER achieve that same load in a cruiser. There's no situation where the vehicle can load the engine as much. It either loses traction or accelerates.

Okay that's great news; I'll proceed and not worry about it
