These are just like the originals except cast in aluminum with the correct 1966 casting # 9782898. These intakes may reqiire gasket matching, and the mounting holes for bolting the intake may have to be elongated a bit. This can be done with a dremel tool. These will fit all 1965 through 1971. Photos are actual photos of manifold.We also sell in the shopping cart the other items you need to complete the intake. Block off kit, carb. studs, water neck, F-fitting, thermostat, etc.
