I have a 600 cfm Edelbrock Performer 1406 sitting in a box in my basement if it's something you might be interested in. It's just a paperweight to me since I bought a new Thunder 650 cfm to replace it. I only kept it for spare parts if I ever need any, but I could give it away just as easily.
Thanks for offer but I have a original AFB that runs good, I just want to put that Duelplane intake on and AFB is too tall to go under hood. Holley fits ok.
