i bought a gt40 mildly ported and polished intake manifold and spacer for real cheap, question w/ stock heads and cam how much hp n tq will i gain, and what will i need to make it fit i already have a 70mm t body, 76 mm c and l and cold air kit on my 95. i would lik to keep these parts if possible. i was told the bolts wont match from the intake to the tbody and no egr is needed, is there some type of transition plate i can but or sumtin to bolt it up???
