It definately isn't similar enough to be a patent infringement and I am sure he isn't patenting it anyway. The runners are a total of 6" long. The style is similar to a BJ's manifold. The radius'd runners act much like a velocity stack and the runners are tapered like a velocity stack. The radius is in the pic on my website.

I am just trying to guage interest right now. I will definately put up some pic's when they are done. The machinist begins production on Friday and I should have the parts Mon or Tues. Hopefully I will have the press bent parts by next weekend.
