The mid 90's 300zx twin turbo rear will handle the power, its the axles that are the week point. There is a fella with an 800 hp 2jz swapped 300 on the stock lsd rear. He only roll races and the rear has held up so far. The chassis will be stiffened with a roll cage at minimum. The basic goal is to just get the motor and trans in and functional than go from there. I would be happy with just putting around this summer with that combination and next year working on the rear and chassis. Thanks all for the comments. I will keep you all updated as I go along.

Kind of a shame to gut a good running turbo car for the swap, but hey, I understand the need to tinker.
The mid 90s tt rear end is still an R200 LSD rear diff, probably just like the one you have in your '86, so you're not gaining anything by swapping that over. The diff itself is plenty strong for the weight of the car, but halfshafts could be an issue, depending on how sticky a tire you use. Keep the V8 low and as far back towards the firewall as you can so the car maintains some handling. That part is tricky with the rear distributor on a SBC.
As for the 'can anything japanese hold up to that torque' argument, the Nissan H233B rear end found in V6 pickups, Pathfinders, Xterras, etc. is about the same as a Ford 9" with a slightly larger ring gear. Plenty strong to hold up to V8 power. That's a solid axle though. The 300ZX is an IRS, but the diff center section is roughly Dana 44 sized.
