Well right now i have a 2000 mustang gt and need some help. I went looking for cars becasue i want something faster than my gt so i was looking at the cobras. I found a 01 cobra for 18,000 and had 38k miles on it. I found an 03 cobra for 26,000 with 20k miles on it. My question is how much horsepower can the 01 cobra block handle before i gotta change stuff? Correct me if im wrog but cant the 03 cobra engine handle like 600 horsepower or something like that? Would it be better for me to buy the 03 throw a pulley, tune, and some other minor stuff or buy the 01 and supercharge it. Thanks for the responses and sorry for the long post.
