Are there any websites out there where people design and build engines from scratch?

Question

Casting aluminum,machining, the whole nine? Haven't found anything yet beyond "Virtual Indian" which is interesting but devoid of mechanical content. I'm a little more ambitious but need guidance insofar as execution of design-my desired outcome is to use over the shelf parts-i.e.Ducati, some Rice rocket periphernalia, to build an engine shell,from a casting, of a unique machine capable or extreme speed and endurance, that has a bit of a retro feel and appearance to it. I have access to a machine shop and already do some sand casting.

Answer 1

Patrick does ground-up work, but they prefer billet.  Link is below.

I don't think sand casting will work for cylinders and heads, I think you have to consider investment castings instead.  Sand casting has too much porosity for high performance applications.

Answer 2

you need proper design software to it
