I recently picked up a 66 barracuda with a 4bbl 273 automatic. It was originally a 2 bbl car and I don't have much history on the engine. Block numbers say it's a 66 and it may be from a dart charger based on the "charger" air cleaner. The previous owner had a new carb installed about a year ago. It is an AFB 4299s, which looks like it should be for a 383. Car runs/starts pretty well except for off throttle cornering (think right turn on green). Unless I go very slow or give it some throttle it tries to die. Same goes for moderate to heavy braking especially down hill. My guess is some sort of float issue, but I really don't know. Only other this I notice is when you floor it, the is a major dead spot for about a second or two and then the engine revs. Any ideas? Help is much appreciated.
