  1. Hey thanks for the input, the mechanic got a hold of me and it seems to be the lifters on the afm side and that’s under warranty from having it done a few months ago
  2. Hey everyone, I’m new on this site and have a question. I have a 2011 GMC Sierra sle 5.3 extended cab with 197,000 miles that just started knocking. With the miles it’s a no brainer to have the engine replaced but I am thinking about a 6.0 I would like more power but the only thing performance wise I’m going to do is a cold air intake and exhaust. So what am I looking at going with the bigger engine or does it make more sense sticking with a 5.3. I appreciate the time and any input will help thank you
