Well I finally finished up this adventure and got it running. I used the EZ Efi system from FAST. It is fuel injection for dummies.. Very easy and trouble free. My home made hack and bash manifold seems to work fine.. I learned a lot about EFI and how it works. The engine fires right up and idles much better than the 600 Edelbrock that was on it. It made 325 horse with a Blue Thunder intake when I tested it in 2010. I hope to dyno it next week and see how the EFI compares. Then I can go about tidying up the appearance. A rats nest of wires currently.
