Had a baby last summer, and things have been crawling since then. I bought a header modeling kit, and have done some work with those. Also ordered a new 3D printer, and have some big ideas.
Here's a practice 3D scan I did of the engine bay.

I made a v-band belt reduction to slow down my harborfreight 14" band saw, and ordered some custom band saw blades so that I could cleanly cut the stainless header tubes.
Trying to get the Try-Y headers equal length around the steering shaft is an exercise in pure frustration.
PS if you're looking into getting the ICE engine works header modeling kit, the basic kit is no where near enough pieces to model even a 4 cylinder full-length header.
