Manual Tranny

I need a good High torque 5 speed tranny for a hp + 350 Small Block chevy.
Saw something on one of the TV shows and they mentioned a "Turbo trans six" ? I don't think I hav the name right.
Street Truck, red light to red light, some highway use. Mostly it's used to scare the hell out of passengers with the toruque it's got.
It has a Turbo 350 Auto with a quick kit. this is our third. The engine just eats it up, we need a manual.

Looked at the Richmond,
Jst wanted some of the "LD SALT's"recomendations

Tremec . . .
