Decided to put it on the big 454 without taking it apart. It started up and ran with only needing metering rods which are easy to change on Edelbrocks. Thank you for a good used carb.
We tried hard to get original 800 CFM AVS to work with todays fuel with no luck, when I installed this 800 CFM it turned the car into a much more enjoyable project wish I had done this much earlier, starts faster, idles better, accelerates better, am very pleased with Carburetor.
