Default What should I make? 370 on spray

Mostly asking to see what I realistically should make to help with clutch selection. Build is as follows:

-370 ci LQ9
-~11.5:1 compression
-Ported 243 heads (done by local, reputable race shop)
-Wiseco Pro Tru 4cc dome pistons
-Rings gapped for spray (can't remember the exact gap at the moment)
-Stock gen 4 rods
-Stock crank
-Tick 242/249 .630"/.610" 111+2 cam (Their recommendation)
-LS6 intake and TB
-Nitrous Outlet 78mm plate
-NX SAFE Standalone (will have either e85 or 110 in it)
-Plan on jetting it for a 200 shot

Full weight T56 car, 9" rear with 4.11s and a truetrac. Will likely stay on a radial since it's mostly a street car.

I know the top end, especially the intake, is leaving some power on the table. I'm thinking I'll make in the ~450 range on motor. I know with the compression I'll likely see more than 200 on a 200 shot, and the main thing I'm thinking about is the torque. I've seen people pick up close to 300 lb-ft on a 200 shot, and just want to make sure I've got enough clutch.

Thanks

Hopefully you got a good idea by now. My car is a 370. Itd 496 on motor and 750 hp on 150 shot on the dyno. So my motor gained 250 hp on a so called 150 shot, your results could vary...
