This is the only cast-iron intake that came on a production vehicle that will mount a Holley 4 barrel carburetor without an adapter plate. No longer available new, this unique manifold carries casting number 3872783, and in reality is a 2 barrel manifold internally with a 4 barrel plenum area. In modified form it works well on 355 or smaller engines running from 3500 to 6500 rpm. Recommended when rules allow Holley 4 barrel carb without an adapter plate. Holley type intakes are hard to find and our supply is very limited.

When available, we offer this intake in all stages of modification,
and we can also modify your manifold.
