You need you a set of long tube headers and a tune at a minimum. Contact Allen at NelsonPerformance.com for one badass tune and pick up some fuel mileage while you're at it. After that you might want to step up to at least an LS6 camshaft.
I agree with Red. Cam, long tubes, and a tune from Allen. I would deffinantly go to 4.10's also. Oh and a converter if you dont have one yet.
or if you like being blown :smile: like me and others on this board...get you a turbo or supercharger pkg and call it a day :thumb: you only gain 100 to 150hp to the wheels over stock and that means fun fun fun!!!! :lol:
Is there any member of this board that wouldn't prefer to be blown? :laugh:
