A friend of mine has a 1997 GT. He was telling me recently he was thinking of getting Lincoln instead because they have more horsepower. He says it would be too costly to upgrade his 4.6 to make more power. I think that's lame. I bet he'll even find that the lincoln is no faster because it probably weighs more. Anyway, I wanted to give him some ideas that aren't too expensive but are really effective for gaining power. I was thinking PI heads and different rear end gears. What else can I suggest to him?
