Is timed vacuum the same as ported vacuum?
There is no ported/timed vacuum at idle, as the throttle plates need to open to produce it. Ported vacuum is vacuum above the throttle plates, and full vacuum is vacuum below the throttle plates, or in the intake manifold.
What causes a Edelbrock carb to flood?
When the carburetor contains too much gasoline, it is said to be “flooded.” Flooding is often accompanied with gasoline spilling out of the carburetor, and sometimes caused by a dirty fuel filter or an improper float level. The carburetor will also flood if the fuel pressure is too high.
Should I use ported vacuum vs manifold?
Most experts suggest a stock engine run a ported connection. A hotter street driven engine should try a manifold connection. In all cases experts agree that a street driven engine should run vacuum advance.
Does HEI distributor need vacuum advance?
See all 6 photos In a GM HEI distributor, vacuum advance is limited by the length of the advance slot. The further the rod travels, the more spark lead the unit provides. Original GM vacuum advance canisters can provide as much as 25 degrees, and possibly even more.
What is intake manifold vacuum?
Manifold vacuum, or engine vacuum in an internal combustion engine is the difference in air pressure between the engine’s intake manifold and Earth’s atmosphere. Manifold vacuum is an effect of a piston’s movement on the induction stroke and the choked flow through a throttle in the intake manifold of an engine.
What size is a 1405 Edelbrock carb?

How do you know if a float is stuck?
One of the signs that the carburetor float is sticking is when the engine will not idle. The float is not letting enough fuel into the reservoir, allowing for a constant idle of the engine. The carburetor float is stuck in the closed position, and only a small amount of fuel is seeping into the reservoir.
Where is the vacuum located on an Edelbrock carb?
Aug 19, · Re: Edelbrock Carb Vacuum Hookups The vacuum present at the driver’s side port on an Edelbrock carb should be exactly the same as the rear port, which is the same as the vacuum in the manifold. There is no flow involved, both points are connected directly to the intake plenum.
What do you need to know about Edelbrock intake manifolds?
Whether you’re building a daily-driven restomod, a high-performance street-strip machine or a full-on race car, Edelbrock intake manifolds will provide the power right where you want it. Performance ranges from an emissions-legal street-oriented bolt-on for daily drivers to a full-on race casting for serious competition.
How much oil is in a bottle of Edelbrock?
Because it won’t rub, scrape or wear off, it is perfect for cold starts and infrequently driven vehicles. Also extends engine life and increases mileage and horsepower. One bottle treats up to 6 quarts/liters of oil. What is the recommended lifter preload for Edelbrock cams and lifter kits?
What kind of torque converter do I need for Edelbrock performer?
With an Edelbrock Performer RPM camshaft a 2,500 stall speed torque converter is recommended. Any torque converters with a stall range from 2,200 to 2,800 rpm would be acceptable. I want to run an RPM cam do my stock heads need to be modified to run this cam?
