Turbo 350 or 400

Hey all, not really a newbie here, I have had my 77 280Z for over ten years, but have recently decided to do the Gen1 Chevy V8 swap. My question is for all you out there that already have this swap, which tranny do you prefer, the TH350 or 400? I plan to build around 350HP at the crank, and would like to keep the RPM’s out of the critical range as much as possible. It will be used for cruzing most of the time, and im afraid a TH350 will really wind out on the highway. I also wanted to know if a TH400 will work with the JTR cross member.

Thanks!!!

the th350 should be fine, the th400 is a far better choice once the torque levels exceed about 430 ft lbs, as its significantly stronger internally but at 350 hp the lighter th350 makes more sence
