ALD-340 is an Edelbrock high rise dual plane intake manifold made before the RPM. You could purchase it from a speed shop of from a Direct Connection source (AKA you nearest Chrysler dealer) and they came with a DC part number as well.
Below are both examples of a DC part and a over the counter part. One is stock, the other modified as per the DC engines book for a TQ and and a mild divider for "Cheating" on the "Must use a dual plane intake manifold" rule.
