efi-diy: Fascinating. Problem is getting a sufficient number of people committed to something like that.
This Vortec 4200 has not yet been recognized for its hotrodding potential. That's a shame. Every knoweldgeable engine guy I mention it to says "yeah, impressive engine", but there is not yet aftermarket, or GM Performance, support for it. The first one in will make a killing, if he can afford the upfront investment that no one else has yet made.

Jim - this is where the whole Hod-Rod industry started...
EFI-DIY: I know fabricators that can get the flanges water-jet cut and the tubes bent for a fabricated manifold.
Also ITB's from a Triumph triple would darn near fit - just need 2 of them
