new carb and intake manifold for 440

[charger2fast4u]

hmm  i hate these debates i was thinking the Performer because how often does a 440 usually go over 5,500 RPM? is there really that much of a difference between the Performer and Performer RPM? how much HP do you need for a 3/8'' fuel sending unit to start becoming restrictive

performer is closer to stock, rpm is more of a highrise, just look at pics on edelbrock site,

edit:  just looked at pics on eddy site, they are from above view, so don't really show the difference, I have a pic somewhere, hold on

[SeattleCharger]

these are from someone on the site's engine, performer rpm, it has been painted here to match engine, but a regular performer is probably half as tall,  or less, and is basically flat looking compared to the rpm

Hey, I made these about a year ago for an intake thread when I was deciding on one,  sorry the regular performer isn't in here, but ya, it is more for maybe a truck or rv I guess, about height of stock intake
   I went with the CH4B, I have a hp and torque comparison saved somewhere that firefighter posted,

[SeattleCharger]

ok, here is a test from firefighter in a cam thread, he wrote:

   "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.

All I can say is that on the engine I have now as it sits in the car based on a few seasons driving with each of a stock intake, a Performer (non RPM), and a Street Dominator that the Holley intake is my favorite of the three.  There was virtually no real world performane benefit from the Performer over the stock intake and the 1/4 mile times actually went down on average over the two years I used it.  The Street Dominator has seen better times at the track while giving up almost nothing on the street.  There may be a slight give in low end torque but it affects driveability in no real way.  What I mean by that is that any torque loss is not sufficient to make normal driving a problem in any sense of the word.  As for torque under WOT driving, I don't do that in town so whatever torque I give up here isn't missed or needed as the conditions I use that under find the advantages of the single plane to soon negate the low end issue.  If all I did was stock street driving, I think I would leave the stock intake on.  If all I did was strip, I would look at a different single palne than the Holley but it would most likely be a single plane.  Is the Performer RPM an ideal street/strip?  Probably, but I have never run the RPM version so I can't really say.  I can say that I would never own the regular Performer again.
Is that as confusing as I think it is?

Hey guys, my bad...you'd think I could remember, I have the Performer RPM.  I've been away a while with the Army and couldn't go look to be sure.  My car runs quite well with this manifold!

[charger2fast4u]

anyone else have or had experience with the performer RPM  would like to get more thoughts on this

[Ghoste]

I think if you are talking about the RPM, you are safe to pull the trigger.  It's versatile enough to be useful on a more or less stock 440 and right on through with a well modified one.

if i got the street dominator manifold what would i do with the EGR and choke provisions  on the manifold

The choke well you just leave empty and the EGR ports just get plugged off.

thanks Ron do you know what kind of air filter you would need to clear the hood with an edelbrock RPM manifold?

[Lifsgrt]

There is a non-EGR version of the Performer RPM.  I just saw a PHR magazine on the shelf today with engine combos...and a Mopar manifold shootout on a fairly stout 383 B-block.  They test 13 or so manifolds, and the Performer RPM once again is called "the best street - strip manifold".  It made 505 hp and upper 400s ft. lbs. of torque on this setup.  As for the air cleaner, on my 440 in my 69 Charger I use an old-school Moroso drop-base 14" diameter air cleaner with a 3" tall element.  It clears the hood by about 1/2", so it's an option, but covers the carb.  The stock open base air cleaner is much too tall, and I'd think a shorter element would be much too restrictive.  For what it's worth.  Jerry

K&N makes a 14x3 in assembly with a 1.25in drop base and it also has the flo-thru top. 

This setup will clear a 2nd gen hood....no problemo !

when you install a intake manifold do you's suggest to just use new gaskets or do you suggest to put on a gasket maker silcone along with the gasket like some people do? if so what kind do you's prefer to use?

I use ultra copper high heat silicone around the ports on both sides for the bathtub gasket and also on the end rails....works for me.
