700R4 Build, tough enough?

[Steelrat]

Here is a list of parts tranny guys are quoting to use for a 700R4 build to stand behind my 70 Nova -

Current car specs-
Engine is a .040 over balanced 400 small block
Block is decked and drilled for steam holes
Scat 9000 crank
Scat forged 4130 5.700" Rods, ARP 8740 Bolts
Mahle pistons 10:44 compression
Competition valve train
Crane gold full roller rockers
Competition Cam 284xe.
AFR 210 Fully CNC Heads.
Hogged out RPM Air Gap Manifold
Custom 950 Pro Series Carb
3:77 gears
Dyno'd at 488 HP 504 TQ @ motor
I have a stock console shifter

What do you tranny pros think? Good parts, good build for the following?:

All frictions (except 3/4 clutch pack) will be Red Eagle coupled with Kolene Steels.
-3/4 Clutch Pack will be High Energy Frictions. (The Red Eagle/Kolene Clutch Pack consists of Frictions & Steels that are too thin which overheats & burns up). -Harden Input Shaft with Reinforcement Sleeve (will accept up to 600 ft lbs of Torque).
-Welded SunGear Shell to SunGear (OEM is weakest part of the 700R4)
-High Energy 2/4 Band.
-.500 Boost Valve
-.279 Reverse Boost Valve
-Transmission will be set up so that you will NOT require any wiring to operate the Torque Converter Lock-up.
-1/2 and 3/4 Corvette Servo assembly. This provides the greatest Clamping available for the Band in both 2nd and 4th Gear.
-B&M Street & Strip Shift Kit which will allow you to shift both Manually and
Automatically.
-All the Brackets, Clamps, Cables, and Linkage necessary to operate your Trans properly and fit in your car Professionally.

Converter suggestions??

Thank you.
