Edelbrock LD4B Manifold
« on: June 01, 2009 - 07:34:37 PM »
I picked up an old Edelbrock manifold for my 318, it's a 4 barrel dual plane.

Has any body run one before? If so how did you like it?

I am planning on running a Edelbrock 600 CFM on it.  Hopefuly this will cure my stalling problem.  :2thumbs:  Glad to know that I scored a good manifold.  :jumping:

It was good enough for Chrysler to put a part number on and list in the old Direct-Connection catalog. If you haven't bought a carb yet consider the ED 650 Thunder AVS. You can adjust the secondary opening point with a screwdriver :2thumbs:

I haven't bought the carb yet, so thanks for the advice.  :2thumbs:

I have a Edel 650 AVS with manual choke.  Using the tuning book that came with the carb, I could not dial it in correctly for my altitude of 5000 feet, was running way to rich.
So I bought an Edelbrock 6593 Air/Fuel Ratio Monitor kit.  Was easy to install, and was accurate enough to tune every circuit in the carb:  idle, transfer slots, main jets, secondary jets, and accel pump.   I'm very pleased with the results.  Bought extra O2 sensor fittings for the exhaust manifold so I can use the sensor on other vehicles in the future....like my thermoquad for the 360 I'm building.   :2cents:

the Holley 570 Avenger is great on a 318 & is a better match CFM wise

Aren't the Edelbrock's rated for dry flow cfm's? I know the Street Avengers are rated for wet flow (fuel and air), which means the 570 cfm Street Avenger puts out 638 cfm at a dry flow rating, comparing apples to apples.

I've got one of these as well.

When you say best for 318, does that mean it has 318 size ports ?

YES. But it's not a problem if the manifold ports are smaller than the head  :2thumbs:

I had one of those on a 318. I took the Edelbrock and LD4B off with a file and painted the intake to match the engine. It looked pretty stealthy with the factory part number on it. You scored a great 318 intake for sure.  :2thumbs:

Well the Avenger probably is wet flowed but it is a tiny carb and very responsive on a 318

In normal times it might be a toss-up what to use on a stock motor, a Holley or a ED carb. Ditto with ED manifolds or one of the others. With today's economy I'll always choose to put my money into the American economy and not send it to China. My :2cents:  :wavingflag:
