Why are the 10's a magic number in your case? To put an X-Body in the 10's you will have to do a tremendous amount of body/sub-frame mods to stengthen it. The rear will have to be greatly modified to take tires/slicks that can get you into the 10's.
In your previous post there was talk of transplanting a Camero/Firebird front sub into the x-body. In my humble oppinion, it would be cheaper and safer to forget the x-body.
This is NOT a bolt in deal. Everything it would take to put this combo together is weld and fabricate. Unless you are real experienced at this, the vehicle will be unsafe at any speed. Why not just find another body with a frame? This would be the better option. There are a lot of Skylarks out there.
Having said that, I see no reason why you can't do it,IF, the rest of the engine/trans/rear are up to what it would take to put that body into the 10's, AND it meets NHRA safety requirements for that speed. This is an expensive project.
A full cage will also be necessary. That engine will be bending/twisting the body everywhere. It is also required by all sanctioning bodies for a car that runs 130 MPH. This is not a streetable combo.
