I recently purchased a Darton Sleeved VQ35DE and noticed the following text embossed on the side of the Cylinder Block. "Nissan Japan AM6 #3"


I am not exactly sure what year model this block is from or if it came from a 350Z or G35. My 2004 G35 6MT has "#5" instead of "#3". I was curious if anyone knew what this means and what the difference could possibly be. i have seen on the transmission the # indicates a different revision (#1 vs #9 CD001-CD009) but wasn't sure if the same goes for the cylinder block.
