Hey guys, the compresson height of the piston is 1.563" according to the manufacturer. I'm at fault for not telling them specificly to zero deck the block. I did tell him that I wanted 10:1 CR though. Regardless it looks like I will now have my block decked AGAIN. Oh well, at least we caught it before assembly. Until I started reading these forums I would have just put it together and then start searching for the reason it didn't run right.
Thanks for being here for guys like me.
