Automatic Transmission - New Tranny Help

My 4LE60 i dont think will be to handle the mod of a D-1SC blower 8 rib pushing 8 psi and the numbers are gonna be badass :D. I need to replace the tranny with a new i was thinking a TH400 does anyone have any good ideas for one that will hold a shit load of power. Im only 18 and the budget is tight any suggestions? Thanks ;)

I recommend going with the Th-400. It want cost alot to build and it will reliable for your application.
