Got a 2005 LQ9 with 110,00 miles from LKQ to start my conversion project. Threw it on engine stand and did a cranking compression test. 270 - 300 psi. WTH!!! I was expecting 190-210. My first thought is user error, but how could i screw up a cranking compression test? Is there something wrong with this engine? I am tempted to return it now. I don't want to install it and have it not work. Any thoughts?

Thanks
