Nope, other way. The adapter makes a power column longer to reach a manual gear box. As said, most people go from power to manual to fit headers and/or save weight. You can probably swap your manual column (or just shaft) for an entire power setup.
BTW, if you have a 4-spd manual tranny, people would beat down your door to trade an auto and pay you. Ditto if a Sure-grip rear-end.
