Hey everyone, I'm not new to the forums but finally decided to make an account, anyway, I have a 2006 Trailblazer with 109k miles. Ive been wanting to swap in a 5.3. does anyone have a link to a swap thread or any info? I'm a mechanic so I know how to trouble shoot I'm just looking for a list of sorts. while I had been lurking in the forums ive seen a few people post about stuff but no solid list. Thanks
