correction, it was a GTX.

it was an optional performance package that came with an intake, higher ratio rockers, and a 3.5 pulley.

GTX packages are originally just appearance packages. the GTX hood is probably one of my favorite hoods ever made. it is hard to find nowadays. most GTX are just a GT/GTP with some body parts.
