Hey everyone, I know that the 1991 mustang gt had a stock horsepower of 225 give or take. I had a set of 373's, mac shorty headers, cai, e303 cam, mac o/r prochamer, and flowmaster mufflers. It was a 5spd with 80k miles and ran fine. I relocated the battery to the back and took out the jack and donut to shave some pounds. I just wanted to know how a race would go between that and my stock 01 cobra convert. with 320 horses. I know that the cobra is faster but how much faster. I figured the cobra weights more than the foxbody gt coupe so some of the horsepower difference could be evened out. just wondering what everyone else things.
