Most muscle car engines from this period used carburetors as the basis for the induction system.

By the early s carburetors were replaced in production by multi-point fuel injection MPI. MPI is expensive. Carburetors are still very popular today, in all the non-production applications.

You could call the Holley cfm carburetor the standard in the performance industry. This specific version has vacuum secondaries, which allow it to work in street applications and with automatic transmissions in performance competitions.

While it is generally considered too large for engines and too small for the big block stroker motors, it is the most readily-available vacuum secondary carb in the Holley line-up and therefore works well on all V8 engines. This carb was not installed on Chrysler production V8s.

However if you plan to replace the production 2- or 4-barrel carb, this is one of the most popular choices. Jets for the Holley carb are readily available from Holley at most speed shops.

With the vacuum-secondaries, diaphragm springs are used to control opening speeds. These color-coded springs are also available from speed shops along with various sizes of accelerator pump nozzles. All of these pieces are used to tune the basic Holley carburetor. To tune any carburetor, break the operating range into 4 basic areas — idle, WOT wide-open-throttlerpm change, and part throttle or mid-range driveability. Different carburetor systems use different parts to adjust or tune these areas.

The idle is basically controlled by the idle adjusting screws 2 in the sides of the metering block and the primary jets.

WOT is controlled by the primary and secondary jets. It replaced the older AFB carburetor. The tuning steps are similar to the Holley except for metering rods and the adjustable air door. There were several 8-barrel carburetor systems used on production engines in either an in-line or cross-ram configuration.

The last production version was built in Mopar Performance, Edelbrock and Indy Heads still offer 8-barrel intakes for various engines. One of the most unique carburetor systems is the Holley 6-barrel which is actually 3 Holley 2-barrel carbs mounted in-line. The basic system starts with a center carb like P and then uses two end carbs like P — one in front and one behind the center carb.

Spacing of the carbs is the same on the big block and the small block. On the fuel side, they are connected by a unique three-Y fuel line. On the throttle linkage side they are connected by a very unique linkage P which allows the center carb to open without opening the end carbs until the engine wants the extra air flow.Note: Allpar does not take responsibility for the veracity of any information or opinions here, does not claim expertise, and is not responsible for any consequences.

Please proceed at your own risk. Cars by name Trucks and Jeeps. Before you start work, replace any cracked or missing vacuum hoses, and check vacuum hose routing against your service manual diagrams or, in most cars, a color sticker under the hood somewhere. Make sure you get the right grade of vacuum hose; anything carrying gasoline or emissions fumes require a special material. When in doubt, get the pricier but safer gasoline-safe hoses. Vacuum hose, gauges, and Ts are sold by most auto parts stores.

Vacuum gauges are usually large dials with a narrow rubber hose or metal hose grip leading out; most come with various plastic tips and fittings. Warm the car up by driving it around for a bit, then connect the vacuum gauge to intake vacuum; you can put in a T and share vacuum with another function, if you plan to use a vacuum hose inside the cabin, or use a port that supplies vacuum at all times.

Caution 2: the Holley shown here was the wrong one for the car; the main difference is the lack of an evaporative emissions hose. On cars with two-barrel carburetors, there are two idle mixture screws.

On cars with single-barrel carbs, there is a single idle mixture screw. It often has a spring between it and the carburetor to increase friction and prevent movement. Bob Lincoln pointed out that if the idle mixture screw does little or nothing, the carburetor is probably clogged with deposits of dried gasoline and sludge, and needs cleaning and rebuilding. Once the idle mixture is producing the highest vacuum it can, and turn the screw in by a quarter of a turn, and connect the tachometer.

The other lead goes onto any ground - an exposed body bolt, the negative terminal of the battery, etc. If it doesn't work, you haven't found a good ground.

Once the idle mixture is set, set the idle speed set up. Set it exactly to the speed on the sticker under the hood by turning the screw in and out; one way is faster, the other way is slower.

I generally set the fast idle speed, which is controlled by the screw that lands on a cam as described earliera few times a year to match temperature changes; the colder it gets, the faster I want the fast idle, within reason. The cam only turns when you hit the gas a little, which moves the screw off the cam, which is why, after you start the car and let it race for a minute, goosing the gas pedal slightly cuts the idle speed.

John Dahlin wrote: "Use a vacuum gauge to adjust your carb idle mixture and you will nail it dead on.

Turn the idle mixture screw clockwise until you feel the screw stop at the bottom and then turn the screw counter-clockwise two complete degree turns.
