I just installed a LS6 intake on my 2002 5.3 and have no use for these parts. All parts are in good working order and have around 54,000 miles on them except the thermostat (new) fuel regulator (new) and fuel injectors (new). I have the following parts for sale: throttle body, throttle cable, fuel injections, fuel rail, intake, harmonic balancer, water pump, alternator bracket, tensioner, intake cover (like new) and oil funnel. I am interested in selling all together or separately. Please make an offer on the whole lot or the parts you need. I can be reached at 661-910-5467.
