Big block Edelbrock RPM
Stock average 285 CFM

Edelbrock Victor 440 Single Plane
Stock average 314 CFM

Mopar Performance Cross Ram Max Wedge 2X4 Casting# 2402726-IM

Stock average 309CFM

Indy Single Plane-- Max Wedge Ports
Stock average 461.8 CFM

Indy Dual-Plane, 440 Port size
Stock average 326.5 CFM

Notes: This intake has terrible core shift at the gasket surface. It must be repaired/upgraded with deep port match and epoxy work.

Max Wedge Cross Ram, 440 port size, 1962-1964 style
Stock average 282 CFM

Edelbrock Torker II 440
Stock average 297.5 CFM

Weiand Team G with Dominator Flange
Stock average 296.1 CFM

Weiand Team G B/B with 4150 base
Stock average 339.5 (This is not a misprint)
Thsi intake doesn't make the power of the victor despite it's flow. Why? This intake falls into what we call the square corner intakes. The fuel/air separation is bad in them, so more power is lost in the separation than is picked up in the greater airflow. Use an Edelbrock Victor!

Holley Street Dominator B/B
Stock average 282.3 CFM

This manifold is designed for a spread bore carburetor, like the M-1. Like the M-1, your money would be better spent on the Edelbrock Victor intake.

M-1 Intake Single plane
Stock average 298 CFM
The stock 440 Victor intake, Stage 1, would be a better choice from both a cost and power standpoint. The Victor is a lower-cost way to get equal or better power.

Big Block CH4B dual plane
Stock average 273 CFM
Notes: Money would be better spent on a new RPM intake manifold.

Big Block Edelbrock 6-pack dual plane
Stock average 302.2 CFM

We have dynoed a hydraulic cammed 493 cu in with stage 1 version at nearly 700HP.

Big Block Edelbrock 2x4Bbl dual plane
Stock average 286.4 CFM

Big Block 1964 300k short ram single plane--Stage 1
Stock average 247.25 CFM
Notes: This was the short ram version.
 
Got any specs with gasket matching/ported/mods...and any on the smallblk intakes...good info....

They are on the site. I wanted to keep it basic and simple for those people that like most will just buy an intake and run it.

On the site you can also find the range of variation between ports and also the numbers after porting.

Ok thanks...will chk it out
 
Sweet list. All intakes tested on one bench is the key to this comparison. Would make a good sticky in the big block section.
 
I wonder about the B vs RB numbers.

Still,'I picked up a nice "B" engine M1 for a good price from a member here and that'll work just fine. I'm not dropping it for a Victor and a few CFM. It's not all that important to me in the street. If I were racing, I'd be looking at the Indy
 
They ***** piss and moan about the Weiand Team G but they brag about the Six Pack manifold makin almost 700 HP? Sounds tome like Hughes is stroking Edelbrock.
 
LOL, sounds like sour grapes from you Bobby! Weird....

I want to have my SB 6 pack ported. Then powder coated.

kind of what I had in mind when I made it. I wish I had this when I was building my 440's.

I've looked and looked for a write up on porting or flow data on a SB 6-pack, came up with nothing.. I'm about to port my mopar 6-pack and was going to do a thread on it, I won't have flow data. As a teaser from a well respected SB expert he said the mopar piece is slightly better. Look for the thread in about a week or two.

No, it sounds to me like Hughes gets their palms greased to try to move eddy stuff.
 
Edelbrock makes a better manifold than Weiand or MP typically. That's not just Hughes. There are plenty of big block dyno posts & articles out there that confirm the Wieand units are just down on horsepower. And this shows that the $400+ Indy manifolds may be worth it if you're looking for a tenth or two.

I sold my Wieand Team G as I've found several back to back tests that confirm these units just don't work as well as the Victor. This would be much more relevant on ported heads vs stock.
 
That may be a matter of opinion,the team g's are still a great intake,maybe a dinosuer but people that use them tend to keep them cause they work regardless of current trend or fad it's a proven warrior..but each has it's place I guess...
 
Sorry but the Team G's only "look" great and sure they work better than a cast intake. Good for the street car. The reason they get used is they're cheap. Certainly woudn't sell a used Victor for $100. That's the going rate for a used Team G.

Big Block CH4B dual plane
Stock average 273 CFM
Notes: Money would be better spent on a new RPM intake manifold.

I would like to note that the CH4B has two distinct advantage over a new RPM... Hood clearance and price. The RPm is the best dual plane manifold on the market for the RB. However, the CH4B is shorter. I still had to use a drop base air cleaner and a 2 5/8" filter to provide adequate hood clearance in my barracuda. An RPM would not fit without cutting or new hood. The CH4B can also be found on EBay for under $100. Got mine for $75.

There is a 3rd advantage for some, the CH4B has a chrysler part number and is allowed in some nostalgia racing classes.

It is by no means better than the RPM, or the best available. However it is a strong performing dual plane that has tested better than the performer and other dual planes, coming 2nd to the RPM in peak power.

CH4B top vs Performer bottom. Look at the runner differences.
 
Yes the CH4B-440 equivalent to LD340 in popularity in the past,were the intakes to have,they worked in the good ole days and for street cars today they can still hold their own,always gonna be something better or flow more etc...but these do respond well also with a little work,nostalgia at its finest...

I agree, The same motor with a dominator Team G vs a Indy intake on max wedge ported 452's and the car slowed down 2- 10's. At least this was my experience. I have always liked the Team g.
 
No, it sounds to me like Hughes gets their palms greased to try to move eddy stuff.

The test below shows the Team G being crushed by the Victor so if what you are saying is true there are a lot of palms being greased.

Here is an interesting manifold comparison on a built 440 from a few years back. The original Torker made the most torque. Kind of ironic and funny.
 
hi, question time!! are they flow testing one port at a time or whole manifold upside down on bench?? just curious.

Well, as usual, my point is entirely missed. I never said the Eddy was not better.

But the FACT is, that there's no way in hell the Eddy WILL be better for EVERY combo out there. No way, no how.

Hughes has profit to be made. They will make the outcome however their sponsors tell them. I never believe anything 100% when there's money involved.

For every dyno sheet you show me with a strong Eddy number, I can pull a strong Weiand number from somewhere.

The fact is, the Weiand is not the POS Hughes makes it out to be. If you think that, I gotta bridge in Alaska goin to nowhere I'll be glad to hook you up with.
 
as i recall the Team G intake has a big indent into the port for the intake bolts.
 
The intake manifold is an extention of the cylinder head. And both are relative to cubic inch and application. Your not racing flow benches, i have seen those be out to lunch, like a dyno a flow bench can be a little happy. It is very interesting how port shape is so critical.
