505 stroker fresh off the dyno - Power seems low? Thoughs?

I understand. Things were being worked on in small stages, and I overlooked it. Been beating myself up for it. It obviously creates a huge unknown. That's what I'm hoping to narrow it down too with this thread.
No big deal ! just trying to help you like you ask us to ! looking at those pictures of your pistons, looks like you may have 27cc pistons instead of the 17cc dish your suppose to have ! really hard to be for sure looking at a picture though
