Yeah, drag strip racing is a lot of fun, but your car doesn't like it. The quickest way to a fast death for any car is by racing them. If this is your fun car, and not one you depend on to get to work, and if you can repair it yourself, and have deep pockets, then keep racing it. Otherwise, decide if you want to walk to work/school or drive a cool Mustang.
14.02 is a damn good time for a stocker. Put a blower on her, and some drag radials, and you will see 13's all day long.
