After chasing down somethings for quite sometime, a fresh set of qualified eyes really helped sort a couple of small things that I looked over. If you have a friend that knows their way around cars that may help.

See if you can locate another harness, and start over, with that if youre not too comfortable tracking down issues. My second harness sure turned out much better than the first.

I really like carbs, but if you plan on putting any miles on this swap, efi is the way to go. You would spend less to buy the new holley ecu and harness than swapping to a carb.
