    give you an example i paid 250 bucks for a 7k mile 02 4.8

    4.8s are not really worth the hassle in selling usually the owner wants more then its worth. Reality 150-500 tops

    its best to keep the motor on back shelf incase the new motor gets hurt
    2002 Lightning - GT headed 5.5Litre w/ Twin 7665s
    2002 Silverado - 427Lsx w/ Twin gt4202s
    2010 Silverado crewcab Z71 - 5.3litre w/ procharger
    2000 Wrangler - 5.3litre with some stance
    2014 Xsport- 3.5 Eco boost
    412 Motorsports

    it ain't that I'm too big to listen to the rumors, It's just that I'm too damn big to pay attention to 'em..That's the difference

    Totally stock maybe 500, but like quik said maybe better to keep as a backup.
