Default GM Performance torque converter help

Got this from a shop that had it from a GM LSA crate motor, they basically gave it away. I've literally been able to find zero forum information on them. Here is all that it says if you look up the part number.

3000-3400 RPM Stall 4L80e/4L85e mate to LS V-8 engine (extended pilot)(single bolt pattern - 11.062")

The SuperMatic Torque converters from Chevrolet Performance are designed to provide long life when matched with a SuperMatic Transmission.

Each converter incorporates the following features:

Steel Billet Front Cover
Custom Stator
''Heavy Duty'' Lock-up Clutch
Fully Furnace Brazed Pump and Turbine
All internal components static balanced
Fully vector balanced as an assembly
Designed for Chevrolet Performance crate engines and transmissions
So I would need to find a flexplate that would work with my 5.3/4L80E that has the 11.062 bolt pattern, what do you guys think about using it with a single turbo and around 600hp?
