Hi. I just recently bought a 1995 GT from a buddy of mine with some minor bolt-ons, and I want to turn it into a weekend street/strip car. I was just looking for some input and opinions from anyone who cares. I'm looking to get about 350-400hp. Naturally, if at all possible. Just any advice on where I should start, and what parts anyone would reccomend would be great. Currently its running these mods.
