440 Intake/carb combo to fit hood?

[///Matt]

my 68 sat 440 has an eddy performer RPM intake and street avenger 750 carb, 4” tall airfilter on a 1.5” drop base. K&N aircleaner filter+cover adds another 1.5” in height. Total height from bottom lip of the valve cover is about 11.5”.

At present, I have a liftoff fiberglass a12 hood, and the aircleaner definitely protrudes up into the scoop.

We’d like to stick a factory side-vented GTX style hood on there. I don’t have one yet, or I’d just throw it on and find out:

Can anyone confirm whether I’ll need to change anything to fit under that hood?

Geez, all I know for sure is that anything airgrabber/ramcharger needs stock height components. You have a little less than 1/2" to play with on a '70. Now, if you don't run the airgrabber stuff, then it would be close, but just might fit....maybe.

If you use your existing carb/intake/air cleaner, you might want to look for a shorter filter just in case. I don't think you'll lose any significant airflow since you have the filter-lid (I love those)

Is the side-venter hoods considered an airgrabber? I’m unclear.

And my intent would be to NOT have all the hood-mounted airbox stuff on there anyway, for cost savings, space saving, and because people whose car is “supposed” to have that stuff deserve to hold on to it.

Oops... you have a 68, not a 69. You couldn't get the airgrabber in 68. I'd say just go for it & see if you can find a shorter air filter "just in case"

Here is what I think you'll need: More drop on your air cleaner base, and a shorter filter.

How you measure the "drop" will matter. Is yours truly 1.5 from the carb mounting surface?

Going from memory, I think my drop is close to 1.75" and I run a 3.25" filter element, and I have some witness marks where stuff touches.

Is this the hood you are referring to? Because its the one we want to fit.

can you post a couple pictures of your setup/hood?

three inch element would help, a little more drop base. and a good torque strap

It'll be a couple of days before I have access to my pics

I have that hood/car (1968 GTX) with a 440. I'm running a factory intake, an Edelbrock AVS (same thing as the original Carter
basically) with a 1" spacer and the factory unsilenced air cleaner. Clearance is not an issue. but there's not much more wiggle
room either.

Yep, that's the 68 Roadrunner hood.

Right, but when you say “airgrabber” do you mean this, or the fancy actuated scoopflap one?

Airgrabber (Plymouth - aka Ramcharger for Dodge, fyi)
68 Plymouth - not available - hood like you have in your car picture
69 Plymouth - "somewhat similar" to 68 hood, but has screen vents + fiberglass box under hood. Standard 69 Plymouth hood is the same hood, but has block-off plates instead of screen vents & no fiberglass box. The airgrabber vents are cable operated. Note: 440 six pack fiberglass lift-off hood also available in 69.
70 Plymouth - air grabber with vacuum operated flip up scoop
71-72 Plymouth - air grabber with flip up scoop. switch is electric these years.

Thanks Beeper! Any idea whether the 68 or the 69 “non-airgrabber” has more motor clearance?

I'm "guestimating", but I think you'd get maybe 2"-3"(?) more clearance with a 68 hood or a 69 hood without the airgrabber box vs. a 69 airgrabber hood.

So when I bought my Charger I have the stock unsilenced 440 Magnum air cleaner, but it was sitting on a high rise manifold and it came with no air filter in it. When I bought the correct one at the local auto parts store and installed it, I could not close the hood. I ordered the drop base from Mancini Racing and I still could not close the hood. So as a last resort I bought a more shallow air filter, so now it has a drop base AND a low air cleaner both to work. The stock one looked about 4" tall, this one looks to be maybe 1.75" tall (but these are eyeball sizes). Is this going to limit my power? I have a 650 on there.....I don't know how big a carb I can go on it, but it came with sounds to the ear like a .30 cam, the Mopar high rise and Dougs headers and the Edlebrock 650. No idea past that what the story is, but the really skinny air filter worries me some, as this unsilenced stock one, was super cool, doesn't seem to have any openings

 

[old guys rule]

whatever you use, get some modeling clay and place it on the highest part of the air cleaner and the lowest part of the hood and GENTLY close hood and measure the clay for clearance. if you feel it to be too tight then go with a good quality torque strap or change to poly motor mounts.

On my 68 satellite with the factory hood, 440, Torker 2, Holley carb, 1/2” spacer, moroso drop base air filter with 3” element.

3/8” between the wingnut and the hood.

The RPM is shown as having a carb pad that’s .680 higher than the Torker 2.
So on my car, swapping to the RPM would have required getting rid of the 1/2” spacer, and I would have then had about 1/4” between the wingnut and the hood.

The Holley SD manifold is noticeably lower and provides for more spacer/filter options with the stock hood.

Thanks! That’s all with the flat factory satellite hood, like the hood in this picture?
