The problem with this manifold is that its height is too tall for me to use my air grabber air cleaner. Although I do not currently have the duct work or scoops installed yet, I would like to be able use the air cleaner for now. Thank you for your help in advance.

The Performer is a stock height, stock replacement dual plane. The Performer RPM is a tall "high-rise" dual plane w/ a cut down divider that makes way more power. There are a few different M1 manifolds too. The M1 dual plane is just an aluminum version of the factory magnum manifold. The M1 single plane is about as tall as the RPM and available w/ either the 4150 or 4500 flange. I have no experience w/ how tall of a manifold you can use w/ the air grabber set up, but I bet you can't get away w/ much taller than stock.

Sure you don't have an RPM? As a9sec70cuda stated, the RPM is noticeably taller and it is a single plane. 8165236-440.jpg (827 downloads)

As far as good street manifolds go, the Edelbrock Performer RPM and the Holley Street Dominator are about the best there is for a fairly mild engine. The Holley SD is much shorter than the RPM, so I doubt it would work w/ the air grabber setup either. Last edited by a9sec70cuda; 06/04/14 12:19 PM.

I want to keep at least the same performance or improve while still being able to use my air cleaner setup. This silly little air cleaner I have on it now is ridiculous. 8165311-IMG_20140604_102635_574.jpg (951 downloads)

I went with the Performer because I was looking for a better flow, cooler manifold temp and I wanted me power lower in the RPM range. Plus, it looks pretty close to factory. If you are looking to get your power with lower RPMs then the Performer is a great manifold.

The only manifolds that are shorter than what you currently have will be the Mopar Performance M1 dual plane (which is aluminum) or a factory stock cast iron manifold. The m1 dual plane looks like this... http://chucker54.stores.yahoo.net/383400duelpl.html Only that one is for a 383/400 low deck. Not sure if they even make the RB version of this manifold anymore? I've seen the RB versions pop up on ebay from time to time. PM sent about factory manifolds. Last edited by a9sec70cuda; 06/04/14 01:05 PM.

If you are looking to get your power with lower RPMs then the Performer is a great manifold. LOL, the Performer AND the Performer RPM are BOTH dual plane manifolds. The Performer saves you some weight over the factory iron piece, but very little as far as performance increase. The Performer RPM is a VERY good manifold, just too tall for a lot of applications. Makes a lot of lowend grunt along w/ good upper rpm power. The Holley SD has almost all the same characteristics of the Performer RPM (good lowend torque and drivability as well as good upper rpm power) even though it is a single plane and is a shorter manifold.

I totally agree. The SD is very short & works fairly well on the low end for being a single plane. No longer available new for an RB iirc but they are around. I hear there are better absolute choices but it works well for what it is & if you need the clearance... live every 24 hour block of time like it's your last day on earth

This manifold may be maybe a 1/4 to 1/2 " taller than the stock cast iron 440 intake. The only way you are going to get ANY manifold that is taller than the stock cast iron manifold on there is to modify the air cleaner base .

If your Performer is too tall, you are SOL. It's about as short as any non-stock intake. That's why they make drop bases for air cleaners. R. Last edited by dogdays; 06/04/14 02:54 PM.

So, I guess I'm basically SOL like you said. I don't see how I would modify this base, nor do I think I should before it comes time to mount the new hood with the scoops and ductwork and see how it fits then. Unfortunately I won't be able to do that until possibly next year or the year after. A drop base would be great, do they make one for an air grabber? lol If anyone else has any other ideas, I'd love to hear them. Thank you again to all that have responded thus far.

Have you checked you air grabber breather to make sure it is a 440 one? The 383 base is taller than the 440 one. If you have a 383 one mounted on your 440 that would give you clearance problems. Easiest way to tell is set it on a table and if it rocks it is a 383. If not it is a 440. Worth a try 69 Road Runner vert 69 GTX hard top 70 Road Runner 4 speed 70 Hemi Cuda vert

I was hoping that it was the wrong part thus fixing the problem. The lid was marked by the seller as a 383 lid though... are there any differences in lid heights? I never knew there was any height difference for a 383 and 440 air grabber, so it never occurred to me that the lid or base could be the problem. The engine in the car is a mild build and seems to like the performer that is currently on her, is there a noticeable performance difference between the m1 dual plane or CH4B and the performer thats currently on her? I would be seriously considering the M1 if it is the factory height as it should definitely fix the problem?? The hood will close with just the baseplate on but once you add the filter and lid,a definite no go. So I believe I need maybe an inch or lil more clearance because the filter doesn't sit very high. I again wish to thank everyone who is sharing their opinions and knowledge.

I have an M1 on my RR and I have no clearance problems. 69 Road Runner vert 69 GTX hard top 70 Road Runner 4 speed 70 Hemi Cuda vert
