I will probably sell RPM. thanks Brian He means where the intake bolts to the heads, the holes are elongated or oversized. Someone may have had a hard time fitting it on their engine and opened up the bolt holes. Intake is still very usable! And that design is very similiar in size to the stock manifold....thus the offer to try that one. Dave

Does not look like the factory dual plane but is available new AND used, is an excellent performer and is low enough to where you can dial in the exact carb position/height with a spacer. Keep old mopars alive.

IT DOES The air cleaner has a velocity stack built into the base. I had to shorten mine. Cut it,welded a plate, cut a hole for the carb. If you want it to seal with the duct work that's what you do.

Eddy did just-that with the TM-7 ...and Holley did just-that with the 440 Street Dominator.

Because the design is very similar, it is reasonable to use the results from the DP4B test as a relative performance indicator for the CH4B. However, a stock manifold was not used in the test. Presuming the dyno was accurate in the test (big if) that would be, for a 383 b-body, about a 12.0 at 111 mph. Edelbrock will make whatever they think they can make money on.

In the 440 intake shootout the ch4b did fairly well.It was down on low end tq compared to some dual planes but did well up top pulling peak hp at a higher rpm than all the other dual planes except for the rpm if memory serves. I run one on my 496 in my c body because the rpm won't clear the hood with the factory air cleaner and it has much better bottom end than my street dominator(big heavy car).A performer will fit(barely touched the hood)but the ch4b pulls harder up top and rpm's higher w/o feeling restricted. my 496 shifts at 5700rpm and will zing 6000+ with ported iron castings,small solid cam,and the ch4b intake with ease.It can move some air.The only mod I have done is have it deep port matched by Hughes engines.To keep the comparison even the same had bee done to my performer and sd as well.

It fits fine with stock air cleaner. No hood issues. Performs well on my mild 440. Better then the torker that was on the car. Not sure if it would fit perfet with air grabber set up. I do beleive it is a tad higher then stock intake.

They make some great products and I am thankful that they continue to contribute to the sport. However, just like every other reputable business man I know, he is in the business to make a profit. If he believed that he could get an ROI better than other initiatives currently underway at Edelbrock, he would do it. If you think otherwise, your kidding yourself.

And again I ask ... if what you are saying is true ... why didn't Eddy just REpop these intakes AS-IS instead of all that R&D ? ... Eddy did just-that with the TM-7 ...and Holley did just-that with the 440 Street Dominator. Well the DP4B is just the B block version of the CH4B, so yes I am going under the assumption that the flow characteristics between the two is basically the same. I am betting the engineers working for holley used basically the same design for B and RB versions of this intake, rather than starting all over from scratch again. Nobody is saying the CH4B flows as well as the holley SD, eddy RPM or TM7. In applcations where there is sufficiant head flow to warrant max intake flow, the CH4B would not be at the top of the heap. But when you need a stock height intake, it's a good choice IMO. Why didn't they repop this intake? Well if you take the CH4B, rotate the carb pad 180*, change it to a spreadbore and add a thermoquad choke well, visusally at least you have an edelbrock performer intake. Maybe they tweaked the intake design a little and gave it a different name so they could keep selling new intakes instead of having everyone going after cheap used pieces? Hey it's possible...

THEN WHY didn't Eddy repop that intake AS-IS .. just like it was produced back in the 60's ? If you look at the results of the 383 intake shootout, the CH4B did very well in 'part 1' where they tested the intakes on stock heads. In fact I think it beat out the RPM in bottom end power IIRC. When they tested the intakes bolted onto a set of CNC ported aftermarket heads, the results were the other way around, but it's all realitive to your head flow and cam specs. Hey DT ...what does a 383 Shoot-out have to do with a CH4B ? .. the 383 intake that Eddy made that is similiar to the 440 one is a DP4B.

I would agree with this. Maybe they tweaked the intake and got the best out of it with more modern tech. Then called it the Performer RPM which is a better intake but a bit taller. I guess they figured the RPM would sell and why compete against their own newer intake by selling an older design. Thats just what I think they may have done but really dont know. Ron

The 440 base is shorter than the 383 base because the intake and carb sits higher on the 440 than it does on the 383. I understand it is really close running a 383 air cleaner base on a stock 440 manifold so running a taller manifold and a 383 air cleaner base may result in hood clearance problems. Some of the guys here can tell you the difference in height on the 383 and 440 air cleaner bases, I'm thinking it's around 3/4 inch. RR's weren't available with a 4 bbl 440 but GTX's were, however it makes the bases hard to find (=$). I don't have a stock cast iron manifold to measure to compare to the above measurements but if you can find a manifold that is actually LOWER than the stock cast iron one by 1/2-3/4 inch you may be able to use your 383 base. (Understand that to do this you will be giving up some top end hp by not using a better (taller) manifold design, but if you have to chose between the air grabber and the intake.....that's your decision.) jt Yeah, it's hopped up to over 160...

It will make more tork similar to the TQ of a CH4B, and look the same. Yet, the top end will run out around 4,800 rpm. The actual Performer will get you good through 5-5200 rpms, making its torque peak a little latter than a CH. The Performer has more plenum volume than the Action + to account for this. Some people say the runner length is to small on the low DP's and a RPM high rise must be used on a 440. FYI-Rpm Mani's can be shaved 1/4" for clearance on a dual scoop hood. Over 224 duration w/3.23's and lets recommend the RPM intake for street use. The RPM can take more radical camshaft than a open dominator intake. At the track w/ 4.10's the dominator is the good one.

Had to look long time to find one.Its about 3/4 inch lower but I beleve I will still have a clearence problem. I don't mind geving up alittle top end to run the air grabber just want to get right manifold the first time.
