Here is a supercharged V8 flathead that I have been working on and off on. I tend to start several projects and jump between 3D modeling, digital illustrating and processing raw photos I have taken with my DSLR Nikons (mostly cars and some landscapes from driving around Nova Scotia, New Brunswick and Maine).
I do not think my engine is to proper scale as I mostly use my 3D models for 3D renderings and digital illustrations and not for 3D printing.
