Does anyone know if the Edelbrock dual plane Performer intake is the same height as the Edelbrock DP4B? In other words, will my carb be at the same height if I switch between these manifolds so my Air Grabber still functions?

Thanks

Performer or performer RPM ??? a regular performer would be a DOWNGRADE from the DP4B , and a DP$4 fits under the stock air grabber , ran one on my 69 bee with N96.

If it's the RPM , not it's TALLER.

The 383 performer that I have is the same manifold as the DP4B that I have, only flipped front to back in the runner configuration and of course is spreadbore compatible. Runner length, shape and cross sectional area is the same.

BSB67,

Can you get some type of measurement to see if the height of the manifold/carb mounting flange height is the same?

Thanks

Edelbrock Dp4b
Surprise! The oldest design produced the best average power of the dual-planes-of course we're only talking 1-3 numbers better, and that can be testing variance, but still, this thing wasn't at all bad. It's the first of the Mopar aftermarket dual-planes but has not been sold in many years. The DP4B designation means Dodge-Plymouth 4-Barrel, and the C4B (Chrysler 4-Barrel) is for 440s. This intake is most like the stock design, with the smaller of the two planes on the right side and feeding cylinders 2, 3, 5, and 8. The coil bracket is not in the stock location, but even so, many people who want an OE look use this manifold.

Price: Ours was $104.39 on eBay, but maybe the price will jump now.

Manifold height: front 311/44, rear 411/48
Peak torque: 456 lb-ft @ 3,800
Peak horsepower: 445 hp @ 5,900

One is on the car, and am not sure if I can get you the answer with the precision that I think you are looking for. Also, my Performer is probably 20 years old. I don't believe that the new Performer has changed as mine looks like what is in the current catalog.

Edelbrock Performer 383
The Performer is the world's most ubiquitous intake manifold; you can order one from virtually any auto-parts chain. The Performer 383 (PN 2186) is a stock replacement part that's emissions legal for many OE four-barrel applications, and it has provisions for an EGR valve. Its carb pad will accept square-bore or spread-bore carbs. The Edelbrock Performer Package recommended for this intake includes a cam with just 204/214 at 0.050, demonstrating that our 237/242 solid cam is a little too big to match the ideal operating range of this and other low-rise dual-planes in this test.

Price: The satin PN 2186 intake is $189.98 at Summit Racing; a polished version, PN 21861, is $359.88

Manifold height: front 331/48, rear 411/44
Peak torque: 455 lb-ft @ 3,800
Peak horsepower: 439 hp @ 5,900

Performer 383

Installation Notes: Recommended intake gasket: #7225. Manifold height: A-3.65", B-4.35", measured to engine block, see A/B Measurements. Port exit dimensions: 1.14" x 2.12".

I have one of each manifold that are not installed on an engine. I can compare the heights. I need a few hours....

bee1971,

Can you clarify the manifold height measurements? 311/44, 411/48 = ???

Thanks

I've run them back to back on a 13.0/108 mph street car. No difference. I think that there is an article comparing theses manifolds too, if you're one to believe in what you read in magazine articles.

I laid the 2 manifolds on the carb mounting face, and the DB4B is about 1/8" taller.

bsakal,

Thank you!!
