Single Plane vs Dual Plane Manifolds

Do you know the difference between a Single and Dual Plane intake manifold? Edelbrock is here to clear that up and make sure you have the correct manifold for your application and use.

Great video. Whichever intake I chose, it will likely be worth more than the engine I'm installing it on...

[garymathews]

you can add a thin 3/8" open spacer to up power on any dual plane intake

I put on a torquer ll and a holley EFI on top of my built 455 and boy it runs strong

[mikeskidmore]

I run an open plenum on a small bock Chevy less mid range less mpg but more Top end.. The mid Range my dual plane from a 1966 327 365 HP Corvette is still impressive .. my guess is Edelbrock has improved some on the 1966 design ..

On the street, always a good idea to run a dual plane intake.

I have a edelbrock intake can I use a spacer plate

[garymathews]

love my rpm air gap for my 427 sbc .ran coolant lines from the back of the intake to the water pump .

[snowsolo]

How about a EFI setup? Will dual or single plane make a big difference or does this only apply to carburetor setups?

Can you explain why my Edelbrock performer intake does not line up with iron eagle heads? Using 1206 gaskets

[ryanmichalski]

With cost not being an issue, and hood clearance not a problem. Would the rpm performer be a bad choice for a stock to mild build 350

The thread on 455 efi torquer 2 manifold..the spray of the fuel in the plenum is different than carburetor. Would be great to have a clear composite manifold with colored fog being pulled in to see the distribution of fuel with a liquid to show density

A tunnel ram gives you both low-mid range torque and high RPM HP.

I purchased 2 different intake manifolds from Edelbrock and had a visual gap at the top of the manifold to the cylinder head port on my aluminum heads I ended up purchasing a brodix Intake manifold and had no visible gap and the ports lined up perfectly. Can Edelbrock explain this problem. No machine shop work was done on engine or cylinder heads

[nuclearbum]

i rally needed to see this now i understand better

[finharms]

Single plane is good for boost as well as fuel injection as they both need the flow for it and both use the open plenum to distribute fuel and air better

I have a dual plane 2131 intake square bore and a brand new holly 4175 spread bore carb I bought a 2692 adapter plate. It looks like it will work but was concerned about the separator vane in the intake as it will no longer separate the barrels. will it perform ok

[Strict]

So if you have an four barrel carb you can't use dual plain intake??

[eternal_gaming]

Hello I have a 1983 cutlass supreme single barrel carburetor and I would like to go with a double barrel can you please let me know which would be a good choice?

[MrStrollerisme]

Ok this changed a couple issues I think. A single plane is a square bore and a dual plane has the jumbo rear throttle plates yes? And yeah a dual plane for the road. Big difference in street rod VS race engine!! Most street rids will never see 6, 000 rpm. And street rods aren't running flat out from stop light to stop light.

I've got a 78 c60 with a 350. Would a dual plane intake be best? Guy is planning to make a small dump truck out of it
