4.3 Help

I may be in the wrong place but I like horsepower too, unfortunatly the 07 Sierra Clasic my wife bought me only has a 4.3. Is there anything I can do to hop this sucker up? Turbo,supercharger, anything bolt on, short of dropping in a V8?

Thanks Wayne  

well a 4.3 wont give too much unless you dump big $$ into it,but every little mod you make to it will be a little better,cold air intake, throttle body spacer,headers,exhaust,and a program should make that 4.3 alot hotter running,and better fuel economy if you can keep your foot out off the floor.
