  2. V8 Engine & Drivetrain
    Hi all, I am doing a V8 swap in my 2009 Colorado and have hit a snag. I am swapping a 2009 2.9L I4 LLV for a 2009 5.3L V8 LH8. I also got my hands on a second trans, a 2009 4L60E from a 4/5 cylinder. I had a transmission shop rebuild it and convert it to an 8 cylinder trans. Some months later...
  3. Engine Swaps
    Hey there, new guy here. I've been reading about V8 swaps for a while and finally decided to take a crack at one. To make it easier on myself, I waited until I could find an LH8 so that I could have the most direct swap possible. Has anyone done this exact swap before? LLV to LH8? Any pro-tips...

  5. V8 Engine & Drivetrain
    on my 09 5.3 Colorado, I was surprised to see there isn't one serpentine belt like most GM vehicles have these days. I have not looked close (without taking everything apart so I can see whassup) but I don't see a tensioner on either of the two belts (AC appears to have it's own belt) Anybody...

  12. V8 Engine & Drivetrain
    Ever since a saw a pic of ahelm3's 2009 LH8 engine I've been curious about the air flow indicator on his truck and why my 2009 LH8 doesn't have one. @ahelm3 Well, from what I can tell GM had these air flow indicators on the early LH8 motors (2008-2009) and then sometime mid-year of 2009 they...
