full manual reverse valve body -- streetable?

No one has mentionned the reason Turbo Action puts those stamps and warnings in the box. You have to be very careful using one on the street. You cannot do first gear burnouts and let off. At no time do you want the tires to be turning faster than the engine... That's how those transmission explosions start. I've used them (and will continue to) for street cars. They are cheap and easy and work... But you should read what comes in the box with them. They are a race part you need to be aware of.
