Edelbrock Air-Gap / Electronic Injection

We develop all here in a mechanical workshop of a friend. It was in TIG welded aluminum blocks (were bars that were cut to fit in the intake manifold, so the nozzles were the same height).

The TBI is that I use a Pro-4D. Since the injection module, search for, 1227730 on ebay, need to know a bit of programming modules electronic injection, I do it here about 10 years. Good reading on http://www.thirdgen.org/techboard/diy-prom/.
