I've got a buddy I chat with on the internet that has an 85GT and we doesn't know too much about it. I know the 87's -92s had 225hp and around 300-315trq stock. 85's made 210fwhp right? The 85 was the last year for carbs...was is a 600cfm holley? What heads did they have? E6? Is the T5 the same in the 85gt's as in my 88gt? Is the cam the same as 87-93's? I aslo know the 85's got true dual exhaust with steel tube headers. any other info would be much appreciated, thanks
