71 4dr Dart 318 w 4bbl

As a daily driver I love the iron Tquad intake, spread bore carb, and duals with that cam. I've run the older 260H and it's a great cam. Economy is all about tuing. The carbs don't know or care what they're on. The Carter AFB is a great carb, and you can get parts, and you have it. I'd keep it. Learn how to setup up your ignition timing curves, and then learn how to tune the carb. The used Weiand is nice, but you have a "good" usable for your application manifold. I'd keep that too. You will get more from a high quality (read as not MP) ignition system than an intake. Get one of those, and a strip kit for that Carter if you want to spend.
