Ok - my very good buddy had his red 1990 GT stolen from his garage (Detroit area - Livonia) while he was up north. It was loaded and putting over 550 to the wheels. The car had 18x9 and 18x10 black bullitts on it with a newly upgraded Cobra brake kit. The engine was supercharged with a Vortech on a beautiful stock block...plus many other goodies, but that's all I have time to list and gives a general idea. If you see the car or notice some parts for sale on other local forums please let me or the authorities know. Thanks guys for your help!
I'll try to post up a picture later today, but I'm working at the hospital now and don't have access.
