After pulling the LT5 this past weekend I finally got around to checking to see what the issue was before taking off the heads. I wanted to confirm how far off the timing was due to lower compression by 20-25 lbs on the entire bank of left side.
Set the camshaft locator
Right side no problem and pins placed.
Left side confirmed timing is off, did not check approximately how many degrees off but I'm sure the experts can tell by looking at this.
Removed pin to try to show how far off.
