thunderbird

Hi, I have a 1996 Thunderbird with the 4.6L motor. I'm about to do my valve seals and timing guides and was wondering what the best performance cams are for a stock motor. I don't want to have to retune everything yet, I also don't have the funds for that yet. Can I just put big cams on my car...

my 95 bird, still not even close to done modifying. Performance 281 (4.6) with under drive pulleys, computer chip, flow master exhaust system, K&N air filter, shift kit, throttle spacers, and no governor. Looks custom stripe paint job, no rust, aftermarket wheels with homemade center caps...
