got a 3.4 i need help
 

i have a 3.4 camaro and its driving me crazy that i have the smallest engine for the 4 gen. can any one tell me how i can get it more horsepower i already got a cold air intake but i need more horse power can anybody help thanx

heads, cam intake ported, turbo or super charger, and exhaust. make sure the cold air intake is actually a cold air intake and not just open filter, it needs to be sealed from teh engine heat (a few guys lost power over the stock intake with just an open filter)
