Was chatting with the previous piston maker. He looked up the job and the pistons were ordered in 2015, for this engine. Here's where things went a little upside down and now things make more sense to me. Piston maker had a crank to deck number of 11.360". I measured it at 11.1875". With the proper deck height, the Arias pistons would have been a 9.5:1 compression ratio.
Makes me feel better about the cam that's in there. Though I still want to call the cam grinder and see if I can get the card for it.
