Gen 5 small block piston!

Thanks for your kind thoughts Hib.

Show me how you "know" the parts pictures were altered.

What you're saying is that GM will not, AND/OR DOES NOT, have a near shape piston top on the DI LT1, correct?

Great CAD design for the top in use with the direct injection. What kind of scares me is the minimal skirt height. That's got to be a lot of stress on such a short height to resist rocking motion, 'specially under combustion. You can see the side coating scraped off the lower LS3 piston in your picture there. I know they had a problem with it ~10 years ago and have improved it but this CAD-design metal removal is getting scary. I imagine this design would increase the importance of always keeping the best oil at the right levels. Certainly worth it!

That was exactly my first thought, as well. Perhaps someone could explain the pro's and con's of the design, when employed on a 'street car'.......Roger.

Update

This thing is still being updated, looks much better than the first issue.
