I Have A 97 4.6l With Cold Air Induction And Underdrive Pulleys. The Computer Has Been Tuned, Also It Has Flowmaster Exsaust With Crossovers. What Is The Best Way To Increase Hp Without Spending The Kids College Fund? Whats The Deal With Pi Heads And Intake Manifold And What Size Thottle Body And Plenum Is Best. Any Other Advice Is Very Welcome.

Thanks,
Ed

Pi head and intake are "Performance improved" found in 99-04 new edges. They will put you up to par with the new edges power rating of 260hp with all the pi swaps.
