I am looking to get more seat of the pants power from my 95 gt vert 5 spd with the stock heads.....my mods are in my signture. Will i notice any seat of the pants power with larger tb,mass air and intake mannifold????If i was to go that route should i send the itake maniifold out and bore it out? Also the motor has 120k so i dont really want to force feed it.
