    5.3 to 6.0

    Ok guys I have a 2000 Silverado Z71 that has a 5.3 that is worthless. It has 275k miles on it. So I want to swap a 6.0 in to it. I understand that I can use my existing PCM is this true? how about my wireing harness? and would it bolt right in and to my tranny?

    Thanks,
    Steven
