Nice casting and core work !

Making your own castings really opens up a lot of possibilities for an engine build.
I think it is the wave of the future.

Great work; we need more pictures !

So what 3 cyl is this?

 

[Paul T]

It is not based on any specific engine but the pistons and connecting rod patterns are from a previous Gem 1 build. Overall size is the biggest my printer would print for block patterns without joining multiple pieces together.
