I have an idea what it's purpose is......

Incredible. A stuffer that goes up inside the bottom of the piston? I'm guessing that's to make up for the volume added by the area opened up under the transfer intake. And transfers that feed from under the exhaust port? Seems that would heat the incoming charge. Very interesting design for sure. Definately won't be bolting these topends on a 460!

I dont like the looks of that 'piece..' It seems like a wall restricting flow, but that may be my opinion... man would that stink if that came loose! bolts and a punched hole through the piston! :D
 
That's interesting. My first thought as well, some sort of crankcase stuffer??

What are those horizontal marks in the cylinder, or is that just weird light reflection?

I'm thinking its less about case volume and more about gas mixture and flow direction and flow speed. I would like to see the relationship between that piece and the intake.

That's an odd shape on the transfer intake, wonder if it really is meant to be shaped like that???? :msp_confused:

I wondered about that as well Niko.
