The TQ fits the exact same footprint as the Quadrajet. As I mentioned in the other thread, there's half a QJ known as a Dual Jet that has virtually the same engineering as the primary side of a QJ carb. It would be just about ideal for a stovebolt engine if a suitable intake manifold could be fabricated. Head and shoulders above any Rube Goldberg dual carb setup, and using carbs that are 40 years' newer production, plentiful and cheap!
