Street 440 - Manifold Choice

[MyMopar]

is it single or dual??

It is a single, as far as sending back the Eddy it is up to you, but you will probably be happier with the Holley SD

 

andalso  you said the edelbrock performer rpm has hood clearance issues with a regular challenger hood??? what is a lat hood???

I made a typo, it is a flat hood.  You need a drop base aircleaner to clear the underside of the stock flat hoods, a power bulge hood (rallye) will be fine.

300-14 is the part # for the SD it will be cheaper than the RPM

hey guys what is the difference between the torker 440 that they dont make anymore and the SD?? Cuz i have a torker 440  and bought the performer rpm a coupe weeks ago but now i am thinking about retuning the eddie and getting the sd But here is my question torker 440 and sd are both single planes so what is the diff???

Height / Runner length and shape.... look at the torker as it has a more turbulant turn before going into the head... SD is more smoother for better airflow....And every CFM more flow equals 2 HP  so 5 CFM is 10 more HP

I believe the Torker has a band of 2500-6000 RPM, where the SD starts off idle.

Listen to your veteran cc.com members... Holley Street Dominator!

  Thats what I'm running on my 440, no complaints runs great!

OK - I am bumping my own post, since I haven't heard anything for a while.  I have my engine back from Best Machine, and I'm ready to get an intake.  I know people like the Holley SD, but I don't want a single plane, and I am not a Holley fan...

Having said that, I am basically down to the Edelbrock Performer RPM or the Mopar P4529118 (picture attached in the first post...Looks like an aluminum version of the stock manifold).  I welcome feedback from those who have used one of these manifolds on a 'streetable' 440.

I purchased an Edelbrock AVS800 (Thunder Series) carb, if that makes any difference to the selection.  Thanks again for your feedback and advice!

 the Holley SD is cheaper then the other 2 & works better ...your call & $$$

I have the taller vintage TM7 intake(single plane) with a 2" 4500-4150 and is tall and a custom dominator on the street and it works great with excellent idle response and is TALL... im sure the low rise single plane holley would be outstanding as others have mentioned to you...

but its your cash 

and yes my car is fully streetable....

Holley is awesome and cant go wrong... I say holley/holley setup

Use the RPM. I would pair it with an 800cfm Thunder AVS, but expect to tune the carb.  I like the SD too on mild builds, but it's not the holy grail if the guy doesnt want a single plane...lol.

Wow - Thanks for the quick feedback, guys. 

I don't want to turn this into a 'Holley vs. Carter' thread, but suffice it to say that I have a 'general dislike' of a certain brand, mostly based on being stranded a few times with stuck floats in their carbs.  I know it's crazy to avoid an entire brand based on one product, but I also won't buy *some car brands* again... 

But really, my preference is based on the desire for a dual-plane intake.  Maybe Holley has found a way to defy the laws of physics and airflow with a single-plane at low speeds, but I have not seen proof that it is 'better'.

So apparently nobody here has used that Mopar P4529118 intake?  Too bad, it certainly looks nice for us 'sort of close to restoration' types!

Ooooh - One more thing.  It looks like Mopar is selling the Performer RPM with a Mopar logo now.  I have attached pics below.  Can anyone confirm that these are indeed the same manifold?

Thanks again for your time and feedback.

Oh the Holley stuck float bit--thought it only happen to me.

Its no biggie but you do need a wide screw driver with you and maybe a pair of pliers. You just unscrew that big screw on top of the float and then unscrew the needle and seat--sometimes its stuck but the pliers will get it turning. You remove the needle and seat, look at it--I never seen anything in it--put in back in about as far as it can be screwed in with the nut on top it should be about even, put the screw back in and crank the motor  until it starts. A 5 min. deal if you have the tools with you.

Most likely its the RPM, Mopar also has used MSD in the past too--because Mopar boxes stink. Not sure if they still do but they had a MSD 7al unit painted black with the Mopar name on it--a great piece for any motor.

I expect the intake is made by edelbrick as mopar is also selling reworked eddy heads also
 I have used the Mopar dual plane intake in alum , it is just a recast of the stock 69 intake in alum so basically stock
 the rpm would be a better choice if you have enough hood clearance , using a taller  intake & having to use a restrictive 2" tall filter is not going to perform very well either , the reason I like the SD is the fact that it will out perform all low rise intakes & stilll allow the use of a 4" tall air cleaner under most hoods allowing the best situation

I have an old Holley S D on my small block. Seems to run just fine at all speeds. I do have an RPM now in my basement waiting to get put on. Everybody says it should work better, I will see.

Funny thing is when Holley first started making intakes around 1975, they were late to the game. They put lots of money in to designing those intakes to work very well, since they knew if they have to be great for people to switch...they did not even make a dual plane until the early 80's and that was because some new cars had 2.45 gears in back--there was no over drive auto trans  back then.

Just to jump in here with a quick question,

The Holley website does not list a "Street Dominator" under Chrysler big-block engines.  It just says, "Intake Manifold - part number 300-14.  Single plane - everything looks right...  Is this the same part we're all talking about?
