I just looked thru all the pics of the build. That is def a R5P7. Looking thru the pics I also noticed something that they did. They pressed a slug into the open deck of the engine to seal it off. I'm guesing they didn't trust the open deck with boost?

I couldn't get the pics off radrides, so here is a pic of my engine with the open deck.
