I shudder everytime I see one of these "how much is it worth" posts, but here goes. I have the opportunity to buy an old Hilborn fuel injection set up. It includes manifold, throttle bodies and stacks, and lines. My intention is to modify it to a funcitoning efi unit. Now before I jump in, how much are these babies going for these days? A new complete efi setup from Kinsler is over 4K. Mine would be similar when complete.
