Edelbrock D64 dual carb manifold. Fits the '64 273 engines. It's never been used on an engine. Ready to use, in as-new condition. I see no defects on it at all, other than a missing stud. It had a little dust, etc. on it from sitting around for a few years. I gave it a cleaning in a parts washer. It's very clean, and only needs a light soda blast to make it shiny perfect. $275.00 plus shipping.
