'01 4.3 to '04 5.3

thats the minimum of your worries...
heres what you may have to consider:
2004 system was fly-by-wire (so the 04 harness and computer are
useless if you are looking to a straight across swap)
so youll need either a 1999-2002 v8 harness (non fly-by-wire) or
a stand-alone harness.
if you use an OE harness youll have to repin your chassis/computer/
fusebox outputs.
fuel lines will need to be adapted or replaced for the v8 options.
and yes tuning for VATS, speedo, and non-emissions compliance

Thank you that was exactly the information I was looking for. I remember reading that somehwere but it was lodged in the back of my brain because I have been researching this for a long time. Looks like I need to keep looking for a 99-02 complete pull out. This guy only wants &#036;700 for the complete &#39;04 and it only has 24k miles on it. Maybe I should just get it because of the price and find a harness.

Either way, thank you for the information. You possibly just saved me a lot of trouble.
