Default Duel four barrels on a 440

Well once again I would like some advice from you guys on an uncharted area for me. This 440 I'm building came with a cast iron duel four barrel intake from a late 50s-early '60s Chrysler 300 and two fairly new Eddie 600s. I'm rebuilding the engine with 2355 speedpro pistons, bowl ported 915 heads, custom cam from Racer Brown, FBO ignition ect. I like the 2 four barrel idea and have had good luck with Eddie carbs(when you get the jetting right). I know the cast iron manifold is going to choke this engine down so I ordered a edelbrock duel four barrel intake since I already had the carbs. I have a hunch that I might should have went with Don at FBOs suggestion of a RPM intake and Demon carb but I would like to try this first. So my question is do any of you have any hints on running duel fours? By the way this going in my '68 D-100

Sounds like you are on the right track.
What gears are in your little D? (might want to add a mild converter for that head snapping hit)
I would say build it, jet it, time it, and see. I have played with dual 4's on tunnel rams, but never a small dual 4.
Also, being the sweptline freak I am, would you mind posting a pic? It sounds like your little truck is going to be flat evil!

Well it aught to be a good sleeper anyway. My converter is a Dynamic street/ strip I got from FBO and has a 2500 stall and will flash to 3500 when you stand on it. Original 3:55 gears in the rear, will go to a sure grip 3:91 when cash flow lets me

Default dual quad 440

Hi 68D100440,

Switch over to the Edelbrock CH-28 from the old Mopar iron manifold, since you already have the recommended Eddy carbs. You won't be disappointed ! It also looks cool. Use the dual quad fuel line from Summit Racing or Edelbrock. Lot's of mid-range torque and decent top end. I shift my 4-sp 440 with the CH-28 at 5600 rpm. The cam is a 230 deg at 0.050" valve lift type from Lunati, similar to Edelbrock's Torker cam, recommended for the CH-28. This is probably milder than your Racer Brown. I can even crack open the second carb in top gear at 2500 rpm and pull hard to 100 mph. Just what you need for your truck. My Roadrunner rear gearing has been either 3.23 or 3.91. Something in the middle would be perfect. In my opinion, the CH-28 is better than the Performer RPM, even with a 750 cfm HP race carb on the Performer. I have run both. You'll like the rush of acceleration as the second carb is opened up on the CH-28.

Of course if you want a vintage look, go wth the old Mopar inline dual quad. Still very cool, and I bet you can improve it with a little porting work,

Mark H.

thanks for the replies. That CH-28 looks like the manifold from edelbrock that I ordered. One thing about it, it will look cool!

hello, my first "hot rod" had dual fours on a OEM intake manifold. a single four will not give you the same feel as a dual quad setup. dual fours are very good for street running. plus will pull at top end. besides, opening the hood and showing off dual quads is more fun over a single four, demon carb,
just food for thought. damn sight more impressive too!! single fours are like you know what, everyones got one!!!

There is just something about the sight of multiple carbs that no fuel injection system can ever hope to equal. Yeah, blowers are cool as well as turbos. However, a N/A engine sporting 2 or more of those obsolete fuel-feeders is just cool.

Last week I was at a fair in Florida where they had a car show of hot rods and specialty cars. There was a '63 Dodge Maxwedge that was a drag champion in the early '60s. It had been restored and the sight of that 413 with dual quads on the short ram setup just left you breathless. I could have kicked myself for not having a camera. I would have shot a whole roll of film on just the engine.

I rode in one back in '63 and it was the experience of a lifetime.

The 600's will work just fine. I ran an old cast iron 2x4 on my 440 in my truck a number of years ago. I used my 426 street hemi carbs,(625's). I rejetted them slightly and they work wonderful. I ran 9.2-1 440 with the MP509 cam, 1-3/4" headers, 10" TA converter, and 4.10 gears. With no strip tuning it ran 12.75 in the 1/4 right off the trailer. They were very responsive and very street friendly. I'm sure you'll love the setup. Dave

Wanna get rid of the iron one? I am doing a low-buck resto on an old 413 Dodge that would like that! :-) PCRmike

PCR; Sorry man, but I'm kind of fond of it. I'm not using it at the present time but you never know when I'll get the bug again. Dave

The Edelbrock CH-28 is a 440 intake. To install on a 383-400, you'll need the head to intake spacers right?

Dodgetruckboy; Thankyou, I like it. It fools a lot of people on the street and strip. Rumblefish; I believe you've got that backwards. A 440 intake will NOT fit a 383/400. But with spacers a 383/400 intake will fit a 440. In fact the 2x4 intake I have is a 383 unit. I made up spacers so I could run it on my 440. Dave

Hey quick. Thanks. I seem to keep forgetting how that goes. I thought it was doable. The RB is a inch narrower than the B engine. So I thought the was the answer.
I have a 400 that I would like to stroke later. The inline 2X4 intake looks like fun.
