You can use the stock intake manifold if you can find a way to water heat it...I believe Langdons Stovebolt.com makes a water heating plate for the 1 barrel intake manifold..if not..its for the offenhouser. What are you doing to the engine? Are you doing head work? And thing to the bottom end? I can give you a ton of info if I know what you want...the type of carb you use is fairly critical pending on what you do. Pm me or let me know.
