I'm looking for a replacement 5.3 Engine for my 2006 Envoy Denali in the Florida area. Let me know what you have.

Thanks,
David
 
I can double check when I get home today. But I think you need to go with 06 and up. The heads and active fuel management are different. If you are planning to swap your current heads and everything to a block it shouldn't matter what year. But a complete motor 06+

That's what I was afraid of. I just posted a new topic about how to know what kind of 5.3 to look for.
