Help me, OB1. What is a DP4B?

[Headrope]

I have dived headfirst into the wonderful world of B block intake manifolds, and keep seeing mention of an Edelbrock DP4B. Is it something special I should embrace or something from the dark side of the force?

What RPM range is the DP4B good for?

[firefighter3931]

Yep, the dp4b is an excellent dual plane manifold. No longer in production but available on e-bay, swap meets etc...It makes excellent bottom end power due to the dual plane design and pulls hard up high due to the increased runner volume. Originally it was sold as a direct connection part and many had a mopar part number cast onto them. I'd say it's descent from idle to 6k.

yes, they are very good intake manifolds. it is a "b" engine version of the ch4b that was designed for the 440 engines.

and the ch4b has proven itself over and over again as also being a very good all round intake.

gezz, you would think since it was a great intake design the manufactures would have stayed with it.

Looks like I'm on the right path. Thanks for the response, folks.

Is it greatly different from the Performer RPM?

 Heap rope, I have one on the 383 in the Cuda says it all.


Ghoste, I have never ran the  Performer RPM intake so I cannot help you on that one.

It's about 6 inches shorter than the RPM! Well... maybe not quite that much, but it's only about 3/4" taller than stock.

It's probably closer related to the Performer than the Performer RPM. Good piece though. I ran one on my 451 and wound it to 6000 rpm on more than a few occasions. Pulled noticibly better than the stock CI or M1 DP.

I have a DP4B on my ramcharger right now (its polished though) meesa likes (star wars pun intended).

im sure the rpm is a better manifold,  the problem with the rpm is the height and then you have to deal with the throttle bracket and kickdown cable, wereas thats not a problem with the dp4b. the dp4b is a much nice piece than the performer.  i swaped a dp4b out for a torker several years ago on my 383 and i gained less than a tenth. that was a 484 mopar cam, 3310 holley motor runing mid 13s at the time.
