WS-6 Trans Am or Firehawk

Which do you think has better performance? A 99 WS-6 TA or a 99 Firehawk? Also, i have heard that Firehawks have a hair greater amount of horsepower than a TA. Why? Do they both carry the LS1 engine? Or maybe the Firehawk just has some other modifications.

the firehawk has around 5 more horsepower because mainly they use SLP parts such as the exhaust, and they high flow air lid for ram air but there not to much faster, a little more aerodynamic though

Firehawks are sexy :D
