I have a 318 out of my 73' Dart Sport. It supposedly a fresh rebuild, and looks to be so. I didn't get a carb with it however I have a Holley 500 4412-3 sitting on my shelf. I know there is an adapter (http://www.jegs.com/i/Trans+Dapt/969/2086/10002/-1) that should work but I was wondering about...
