340 Intake manifold help
The 1973 340 Cast Iron Intake Manifold > {#3671918}
It is kind of 'clunky', and has a few more EGR ports than the 1971 Manifold,
and the 1972 Manifold.
Though it flows well for a 'stock' unit, it has a bigger Heat-Crossover passage
than the earlier 340 Intake Manifolds.
It is 'bulky' as well {nearly 50 lbs}.
But that being said, that 'Baby' loves the Thermoquad.
