Will a Holley carb fit on a quadrajet intake?

What is the difference between a Holley 4150 and 4160 carburetor?

Which carb spacer is best?

The 4-hole plenum spacer is most effective when it’s made from phenolic resin or a polymer. And the good news is that phenolic resin spacers can be stacked, the same way as wood or aluminum spacers. So if insulation and durability are both important to you, this may be the spacer for you.

Does a carburetor spacer add horsepower?

I asked owner Keith Petelle how a spacer works to increase horsepower and torque. He said, “It helps improve the air-fuel distribution into the intake manifold.” A carb spacer increases the distance between the intake manifold and the bottom of the carburetor, which reduces the velocity of the intake charge.

Is a carb spacer worth it?

Spacers are said to improve air/fuel vaporization through and out of the carburetor. Anytime the air/fuel charge has to turn sharply coming off the carb, it increases the chance of separating the fuel from the air. Spacers also have an insulating affect, tending to cool the air/fuel charge.

How do I know what cfm carb I need?

The formula for calculating how much CFM (cubic feet per minute) your engine requires is: CFM = Cubic Inches x RPM x Volumetric Efficiency ÷ 3456. Any ordinary stock engine will have a volumetric efficiency of about 80%.

How much horsepower will a 650 cfm carb support?

So, using your Google-Fu you type “How much power can a 650 cfm carb support?” Well, chances are that you’ll get answers in the 450-470 hp range, but that’s not really the right way to look at it.

Is a 750 cfm carb too big for a 350?

Rule: For maximum performance, select a carburetor that is rated higher than the engine CFM requirement. Use 110% to 130% higher on single-plane manifolds. Example: If the engine needs 590 CFM, select a carburetor rated in the range of 650 to 770 CFM for a single-plane manifold. A 750 would be right.

What happens if carburetor is too big?

If the carburetor is “too big” then the engine will not be able to keep enough air flow through the barrels for fuel delivery to occur. Which would explain why the engine would work at highway speeds but struggles at low rpms.

What size carburetor do I need for a 350?

A 600-cfm carburetor may perform quite well on a stock 350 Chevy. However, the minute you start weaving in power adders like a hotter cam, a dual-plane performance intake manifold, and aluminum heads you’re going to need 700-750 cfm.

Will a bigger carb make more power?

A larger carb will flow more air/fuel at higher rpm and give more top end and higher peak hp.
