Thanks for posting these pics Jerry, it was the piston windows that I still had the most questions about. I'm doing a 028 super right now, I just put up my tools and came in, I've got my cylinder finished and plan to work over the piston in the morning. I didn't know how much I should open up the windows, but after seeing how much you opened this one I now have a better starting point. Great looking work, I think you may have done this a time or two. Thanks again for the posts, rep sent.
Every little bit helps flow but don`t go too far,keep the structural integrity , just open, blend,and remove bumps and casting lines, this lightens up the piston some also.
