Product Description

This single plane design intake is great for high end flow (5500 RPM+). If you have a stroker motor or a very healthy 3.5 and are looking for that little extra up top, this is the intake for you. We run this on BAD 8 which pulls nicely to 7000 RPMS.

 

These are also drilled and tapped for a thermostat housing. Which can be purchased here. This is not the case if you buy this anywhere else. We garuantee the intake will fit properly and you will not have to mess around trying to find a thermstat housing.

 

 

"Generally, intake manifolds come in two major categories: single-plane or dual-plane. In a single-plane manifold, there is just one hole under the carburetor; in a dual-plane, there are two holes under the carburetor. In the single-plane configuration, all cylinders of the engine draw from all barrels of the carburetor. In the dual-plane configuration, the opening under the carburetor is divided into two halves, such that one half of the cylinders draw from two barrels (primary and secondary), while the other half draw from the other two barrels." Dan Master

 

"Rule: "Single-plane" is better at high RPM; "Dual-plane" is better at low RPM.

At low rpm, the intake vacuum signal from each cylinder is fairly small. Dividing this small signal between both primaries in a single-plane manifold results in a weakened air flow through the carburetor, resulting in poor low RPM performance. At high RPM, the intake vacuum signal is high enough to draw properly through all four barrels - primaries and secondaries - so the engine runs strongly at the elevated RPM range. The converse is true for a dual-plane intake. At low RPM, the vacuum signal from each cylinder is sent to only one side of the carburetor, resulting in a good air flow. At high RPM, however, airflow through only one side of the carburetor may be restricted, choking the engine."- Dan Master
