Yes. I do believe those specs say a dished piston. Upon further investigation, this engine has flat top pistons and the heavier duty rods indicating a 10-1 compression and a 345hp version of the LQ4.
"The Vortec MAX engines had higher compression ratios of 10:1 and included flat-top pistons for increase power output. The gear ratios were also altered to improve towing capacity, with a towing capacity of 10,800 pounds. While suspension and brake packages we’re available to most models, all MAX engine vehicles had thicker front sway bars, four wheel disc brakes, a heavier duty transmission, and a larger 9.5″ rear end."
