Mopar intake manifold

All SB 4bbl factory manifolds (so far as I know) were spread-bore starting with 71

In 72 they had EGR without a valve. This consisted of "floor jets" in the bottom of the plenum which connected with the exhaust heat crossover

73/ later they had external EGR valves. Never heard of a QJ specific manifold, AKA either TQ or QJ. I about **** the first time I saw a FACTORY Mopar QJ "back in the day."

They are considered to be very decent manifolds
