FIrst let me start by saying hello to everyone as this is my first post here. I bought a 2000 Impala LS, with 12 valve v-6 a few months ago and like it okay thus far. Haven't done anything yet so my engine is completely stock. Everything has been fine so far but I need more power. This is the first car I have had that I really cared for enough to do anything to so I am going to try and beef up the engine a bit. My question to you folks is where would be a good place for me to start at?
Also, what is the most cost efficient mod to give me the best horsepower gain?
