I just bought my '98 GT about a 1 1/2 months ago and have been doing some research on building NA. But this seems to be absolutley ridiculous because doing so costs an arm and a leg for not so impressive power gains, I guess I am just used to the good old 302. Anyway when the funding permits I plan on getting a supercharger, but wanted to hear other peoples recommendations. I was leaning towards the Kenne Bell twin screw. They will be making a 96-98 GT version, but wouldn't it be worth it to upgrade to PI heads and get the 99-04 version? What else would I need to upgrade to do this. Please post any other companies you have experience with.
