440 Intake

[Moparbob]

Hi,

Can anybody recommend an intake for a 440? It will have a mild cam it it otherwise semi stock,, for now Ive got a couple of holly 750's so I will use one of them. 

[flyinlow]

I have a Edelbrock Performer RPM on my 446. Great mid range torque.
Tall intake, you will have to redo carb/trans linkage. I have 3/8 insulator under a Edelbrock 800 carb with a 4 inch tall drop base air cleaner. Clears my VFN fiberglass bulge hood by 1/4 inch.
No heat cross over . Does take a while to warm up on a cold day.

I have a Holley Street Dominator with a Thermoquad. Less low end.(could be thermoquad tuning) Seams to pull harder 5000 + rpm.

Use the performer rpm most the time. Would recomend it.

Bob, look around for a used CH4B....these are excellent manifolds and work fine with stock throttle/kickdown linkages. 

Here's a recent thread on the same subject :

2nd that on the CH4B 

this one is a bit high in price but its alredy been blasted

So thats a good choice? What do they normally go for? We have a bead blast cabinet in the shop.

[firefighter3931]

Bob, the CH4B's usually go for $100-$150. I would avoid the manifold in the e-bay auction above because it has been modified...the center divider has been milled down/removed. You want an unmodified piece with the center divider intact. 

The divider is important because it increases torque and throttle reponse at lower engine speeds. Eliminating the divider converts the dual plane into essentially a single plane. Single plane manifolds work fine in the right application but it's not the right choice for a build like yours.

they average about $125.00 give or take + shipping . like i said that one is high on price . if you have time just keep your eyes open on Ebay search mopar intake & 440 intake and pay attention to the photos on the listing page not all CH4B intakes are listed as CH4B when i found mine it was just listed as aluminum 440 edelbrock intake .

my bad i didnt even notice that the milled out the divider

Randy, the center divider is the first thing i look at on these 30 year old intakes. Many of them were butchered early on in an attempt to squeak out a few more top end horsepower. Unfortunately those type of mods come at the expense of torque & throttle reponse. 


No worries bud....now you know what to look for.

And yet at one time wasn't it more popular to epoxy popsicle sticks into the bottom of the plenum to create dividers?

[firefighter3931]

Yes....commonly referred to as the Vanke Mod. This was used primarily on the aftermarket Edelbrock crossrams (STR14 & STR15) to help with fuel distribution and reduce fuel puddling in the plenum area. Keeping the fuel in suspension is much better than having it sit at the bottom of the intake manifold. 



Ron

[Ghoste]

I had thought it was a common thing with many of the intakes used in Super Stock at one time.  Mainly those STR's though huh?

RON is that VANKE MOD in refferance to ARLEN VANKE ? there is a guy that lives  here in cranberry twp pa. whos restoring Arlen Vanke's 63 Polara 426 max wedge drag car the "EXECUTIONER"

It is Akron Arlen that he is talking about.  He also did the mod for the 67 Hemi Super Stock program but those were all Street Hemi intakes.

[SeattleCharger]

oh ya, the CH4B, I bought one after reading the thread link below.  I saved this older thread about the CH4B, scrolling down the thread you see firefighter included a hp and tq comparison of various intakes,  read the thread for more info, or I just copied and pasted firefighter's post from that thread below:

      http://www.dodgecharger.com/forum/index.php/topic,21355.0.html


quote from firefighter:
"I found the article : it appeared in the july 2002 issue of Mopar Muscle and is titled "Induction Extraveganza" (p.36)

The article is several pages long and they don't have a table with the results listed all together so i'll list them below.

(1) factory 70-71 iron manifold: 575hp@6200/581tq@4000
(2) Edelbrock CH4B : 607hp@6400/573tq@4000
(3) Wiend action plus : 597hp@6300/564tq@4000
(4) Edelbrock Performer RPM : 610hp@6200/590tq@4000
(5) Holley Street Dominator : 636hp@6200/598tq@5000
(6) Edelbrock Torker (original) : 605hp@5500/608tq@4700
(7) Edelbrock Torker 2 (new style) : 627hp@6300/593tq@4900
( Edelbrock TM7 ( old Tarantula series) : 618hp@6200/602tq@4900
(9) Edelbrock Victor : 637hp@6400/593tq@4700
(10) Mopar M1 (single plane) : 629hp@6100/589tq@4900
(11) Wiend team G (single plane) : 597hp@6300/569tq@4900


As you can see from these results ; the single plane manifolds all pushed the tq peak up into the 5000 rpm range while the dual planes were at peak tq by 4000 rpm. The Holley Street Dominator had the best average HP in the 4000-6600 range (572hp) and the best average TQ in the 4000-6600 range (571tq). This motor build is more of a race type combo and wouldn't represent what the average street guy would use. The dual plane is definately the way to go for a mild street application where most of the engine will spend it's time in the 2500-4500 rpm range. These results correlate with the dyno testing we did on my 446....The RPM dual plane made better TQ below 3500 rpm but fell off around 5800 where the single planes kept making more power. That's why it's so important to match all the components in order to achieve the optimum results.   In my case the RPM made 30hp less than the Street Dominator at peak hp.

The factory 70-71 manifold looks pretty descent as does the CH4B which made over 600hp on the test mule. That's pretty impressive for a stock height dual plane intake manifold, inmo.

Yes Randy, that would be Mr Vanke. Man that is a cool old racecar....awesome ! 

I met Mr. Vanke at the Norwalk classic a few years ago....very friendly and personable fellow. 

It is Akron Arlen that he is talking about.  He also did the mod for the 67 Hemi Super Stock program but those were all Street Hemi intakes.

I believe that is correct Ghoste....he also did lots of intake mods on the Hemi Rat Roaster intake manifolds as well. There are several tech articles in the old Direct Connection race bulletins that outline his work.

Are there any new manifolds that would perform as well?

[flyinlow]

Performer RPM IMO

As mentioned above...the RPM is an excellent alternative allthough it does present some obstacles with throttle & kickdown linkage. You would also need a drop base air cleaner assembly so all this adds considerable expense.

The Wiend "action plus" looks descent and is similar in height to the CH4B with a more straitforward installation. That is another option but my first choice would be the CH4B. Patience grasshopper, one will turn up on E-bay soon enough.

I wait, I watch, I learn 

[flyinlow]

If you end up with an intake that needs the kick down linkage redone. Resist the urge to leave it unhooked and shift manually. Can make trans. slip.

[Silver R/T]

street dominator is best for mild/stock builds imo You lose a bit of low end torque but you gain mid-high range
