TH400 Convertor build

[buickboy]

I just had a brand new TH400 trans built and now need a convertor built. Intend to go with a local builder with a great rep. Can some tell me what internal/external parts are absolutely necessary when building a convertor and not take out the motor thrust bearings. Car is race only, no street at all.
70 turbo. At least 3500 stall reccomended. Help please!

There are a few Threads on here about the Orifice sizing to prevent Crank Thrust Bearing damage. Here's one>> http://www.turbobuick.com/forums/tr...400-charge-flow-pressure.html?highlight=TH400
