fuel injection

I'm pretty sure Professional Products bought them out - I saw the Professional Products version at PRI last year. It's an interesting idea but I suspect a more conventional TBI (or Holley's Commander system, for that matter) would have better fuel distribution because the injectors on the Retrotek / Professional Products unit were nearly sideways instead of vertical. Its biggest selling point is that it looks like a carburetor. It also looks relatively easy to install.
