Junk in my trunk.

RustyRat Rod there are three intakes, all supposed to be 340. The first is a edelbrock aluminum, looks older. The other two are cast iron.

The second intake here is the 73 340 intake. Great piece. The third intake is a 72 340 intake, actually a touch better than the 73, but both are very good intakes. Probably outflow whatever aluminum intake that is, unless it's an LD340.
