Re: I need more power :)

you could gain a good 30 horsepower from vortec headshttp://www.summitracing.com/parts/NAL-12558060/(read the discription at the bottem) but they require a differnt manifold that what you have stock. you will also need self aligining rocker arms but then you could go to roller rockers and pick up more power. and add a set of headers and a new chip custom built for the set up and you should have a good bit over 50 horse power.
