My 07 Burb LTZ has finally called it. its definatly pulled its weight racking in 400k+ so i cant complain much but now im looking to do a quick simple swap just for reliablity. I plan on doing a blown l86 but for now the truck just sits as i travel for work and will be sitting for the most part for a while. dont plan on replacing rear end and tranny until i do the l86 so what do you guys think?
