Edelbrock Single or Dual Plane??

[Dlarge]

Im running a 440 in my 66 Belvedere! Refreshed up everything in the engine bay!! Ive had people tell me for my set up i need the Dual Plane. When i got the car it had the Single Plane witch I'm using now. I have a 750 Edelbrock carburetor, with the single plane intake, and i don't know what cam is in there! What you guys think i should be using? Whats the difference?

That should give you what you are looking for.

What single plane manifold are you running now? Does it start and run ok? I have a single plane Edelbrock on my 440 now and it works good. Not that much different than the dual plane intake that was on it. A little more top end power. A little harder to start when it's cold and a little rough till she warms up, but not bad. If it's running good with the single plane manifold that's on it I wouldn't bother buying another unless you wanted it to make the engine look closer to stock.

I have the performer RPM air gap and it is dual plane. I have had Torkers in the past and they were single plane.

To be honest I would never get a single plane for a street car again that combo sucked.

OK, here is my 2 cents... with that small of a Carb (assuming it fits your build) you need a dual plane intake! I have run all types and built many cars and a street combo should run a dual plane, easier starting, better low torque and that is what you feel on the street.
So, there it is....

Definately dual plane for a street driven car. If you plan on a street/strip vehicle then single plane but that 750 must go. Mopars tend to really like single plane manifolds on the dyno. In most cases they pick up HP and torque with like a M1 but for street use the dual plane is the ticket. You really need to figure out what cam you have because if it is small you may want a Performer instead of a RPM manifold. If you are planning later on changing the cam to something larger the RPM would be better choice. I am using a Weiand 8009 dual plane on my 440/512 build for my 66' Satellite. Preliminary desktop dynos results say around 600 horsepower and 650 foot pounds of torque, oh yes.

as others have said,run the dual plane on a street motor for easy starting, better low end responce and torque.your 750 also works fine for a street motor.if your car is a good driver the way it was,then stay with the single plane if money is any sort of issue.dual plane will just make it more"streetable"but not something you must use.

I would first ask you, "are you lacking in torque now"? If you can burn the **** out of your tires as it is, then I wouldn't dream of buying a dual plane intake. A choke on the carb should get you past any cold start / drivability issue you "might" have with the single plane.
BTW, I don't think 750cfm is as much as factory in 69', but you should have some pretty good throttle responce out of it..LOL!
