What kind of intake manifold does a Pontiac V-8 use?
The induction system of a Pontiac V-8 typically consists of a carburetor and intake manifold. Each is designed to maximize performance in a particular range. Larger race engines that operate at high speed require a significant volume of fuel and air, and that requires a unique intake manifold with multiple carburetors.
When did Pontiac stop using multiple carburetors?
The original 4-barrel produced through 1967 is best left for restoration applications. The use of multiple carburetors was banned by General Motors for 1967. Pontiac developed an all-new cast-iron intake manifold for its high-performance engines that model year.
When did Pontiac stop using 4 barrel manifolds?
The new manifold proved to be so well suited for myriad applications that it became Pontiac’s only 4-barrel from 1968 forward, and the original design was discontinued. Over the years the casting saw the addition of an exhaust gas recirculation (EGR) system to quell certain emissions, and even physical deviations.
When was the EGR added to the intake manifold?
The basic intake manifold casting was modified to accept emissions equipment over the years. An exhaust gas recirculation valve (EGR) was added to its passenger side in 1973. It remained in that position until traditional V-8 production ceased in 1978. Despite the negative perception, EGR didn’t affect the performance potential of the castings.
When did the 4 barrel intake manifold come out?
Its coolant passages and mounting points were revised for 1965, making it compatible with popular Pontiac cylinder heads commonly used today. Pontiac introduced a new 4-barrel manifold when multiple carburetion went away for 1967.
Why do I need a singleplane intake manifold?
The design causes air velocity within the manifold to suffer at low engine speeds, affecting engine effi ciency. Generally speaking, a singleplane manifold is best suited for engines that regularly operate at moderate to high speeds, and spend little time loaded at very low speed.

Which is the best intake manifold for a car?
Engine displacement can also influence it. Larger engines tend to pull the power range downward, so a particular manifold that produces greatest average power from 3,000 to 6,000 rpm on a 400-ci, may work best from 2,500 and 5,500 on a 455-ci. Intake manifolds can be classified into two distinct types, and it’s directly related to plenum style.
How much does a 1966 intake manifold cost?
The center 2-barrel carburetor is larger on the 1966 manifold, which increases its desirability and can improve performance, particularly with larger engines. Depending upon condition, a bare early-vintage manifold can bring $100 or more. A 1965 manifold generally cost a few hundred dollars while the 1966 units can bring several hundred.

When did GM stop using plastic intake manifold?
This plastic manifold was used on most 3.8L GM engines from 1995 thru 2005. The fix, involving replacement of the upper plastic (composite) intake manifold, gaskets, and peripherals is costly; but much less expensive than replacing the engine, which will have to be done if this repair is not completed.

Where do I find the intake manifold code?
Intake Manifold CodesFred Schramm2013-09-04T21:44:05-05:00 Intake codes have casting codes on them as well and with the date code you can determine what engine it came on. They are located on usually on the number 1 intake runner by the thermostat.
How big is the intake manifold in a Pontiac?
An essential copy of the cast-iron manifold, the runners were raised about .125 inch to match the cylinder head intake ports and improve airflow. To isolate the manifold from excess heat, a separate cast-iron exhaust crossover connects the cylinder heads.
