I'd get 2 Edelbrock strip kits for the model of carbs you have & yes peruse the Edel site for tuning info. The 1406's are a bit lean. I'd get a vac gauge and a tach & go the next size up in pri jets (.098" iirc) if running 1406's then finalize the timing (initial/total/springs/vac adv) & then start on the carb & note your in gear idle speed vacuum number for a tuning start. EDIT No chokes in the pic so they are likely 1405's & would not need to be jetted richer before you work with the ign timing. Correct the timing then the carbs

We run that set-up on a friends 440. 600's, stock jetting. Accelerator pump rod in the hole closest to the carb throat. Car runs(11.50@115). Depending on your cam you may have to change metering springs. With the car idling in gear loosen the metering rod/piston access cover. Rotate it and watch the rod/piston assy. If it's bouncing up and down it needs a lighter spring. If not you can go stiffer to help with mid range. Even my 15-1 572 with a 285@.050" cam runs only 2 sizes up on the primary's, no chokes and a 2nd inlet line. Other than that they're out of the box (9.25@147). good luck Doug

So you are replacing your tunnel ram? I know someone who went from the edelbrock setup to a tunnel ram. Same edelbrock carbs on both manifolds. The tunnel ram had much better upper RPM power- but Im sure you know that. The underhood dual fours are very 1960s cool.

Exactly... "Pay attention to the needles at idle".
Edlebrock has online the owners manual. Read it a few times until it "sinks in". Be sure to read it again after the the first time running the car also. All the "bulbs will come then"
I've been tuning that carb since 89 or so. I have been all the way to 14000 feet with my 1405.

Planning on installing this on my 440, wanted to know what carb book or online reference will be good for to learn how to tune the edelbrock carbs.
I've always had holleys and this will be all new to me
Super Tuning and Modifying Carter Carburetors by Dave Emanual
Edelbrock carbs are Carter Carbs. This is the go-to book for me when I'm trying to tune a new Edelbrock (or old Carter).
Available through Amazon:
http://www.amazon.com/Super-Tuning-Modif...ter+carburetors
Though I bought mine at Half-Price Books for, well, Half what Amazon wants for a new copy.
Enjoy! CC.

Thanks Fellas, Really appreciate the info I did read some of the info on the eddy site but didn't know if they were just making it sound simple. Two bolt main, my Fury for the past year/ 18 months or so has had a single 4 bbl on a performer RPM, I am using the Tunnel Ram motor in something else. The Fury was begging for a better look under the Hood, to better match with the rest of the car.

The wide 440 looks perfect with dual quads. You will be very happy with the performance and even people who dont care about musclecars will stop and look in admiration at your engine when the hood is up.

That progressive linkage sounds like a good idea to me. Interesting that you can/would spread out the accelerator pump fuel squirts over a longer throttle position. Like Stage 1 2bbl forward carb primary open Stage 2 6bbl forward carb secondary and rear carb primary open Stage 3 8bbl all guns open! TOO COOL

In progressive linkage, the Main carb is the rear, it opens its primaries which has to feed all eight cylinders, and is responsible for most of the idle tuning, then it opens the Front carbs primaries, and then secondary's on rear carb finally the secondary's on front carb progressively opening them in sequence or exponentially to have all eight open at WOT.
The eddy carbs tend to be a bit lean anyway so the rear carb needs to have bigger jets to try and compensate.
I rather have both front and rear work in unison or tandem. Cross rams work with 1:1 because each carb feeds a different bank, this would be the same principle if the plenums were split which they almost are with this intake.
Havent you heard most guys cant seem to tune a six pack worth a dang, Thank the progressive type of linkage and tuning carbs for different jobs on the same engine.

I don't like progressive linkage, I am running them 1:1 The primaries in the back carb would need to be bumped up a lot so it doesn't run to lean.
I rather spend the extra fuel for tuning ease and performance. had My tunnel ram with holleys and was very happy.
