Will a performer RPM, new Edelbrock AVS and a 1 1/4" drop base air cleaner fit under the stock hood of a '68 Charger?

If its the K&N drop base filter, it should work. I'm not exactly sure on the measurements, but I think I have the same setup and am still running the stock hood, its fairly close though.

Yes.  I've got the dropped base with a 3" K&N filter.  I'm running a Holley D.P. though.  I had to grind down the width of my kickdown linkage a bit to keep it from hitting the bottom of the base.  Bob

Keep an eye on the distance of the choke horn to the inside of the lid. You can really restrict things with a drop base without realizing it.

Yep, alot of people use a drop base and get the K&N filtered top.

I didnt when It was a 440,but I have one I can switch back and forth for my 493.....another thing thats nice about the race carbs is that they dont have a choke horn so you have a little more flow with a drop base.

Not sure if you've tried already, but I just tried a drop base on my AVS/RPM combo and it's a no-go.  The base was pushing on my fuel line..sheet.  I swapped back on my demon thinking I'd get a drop base for that this week but it runs like a$$ compared to my AVS. I heard one can get a fitting for the AVS fuel hookup that angles it down...hoping that will work.

The fitting that you need is the one for a Hemi dual 4bbl. set-up.

Hey Brian - my 440 is not stroked like yours so would you still recommend a proform over the 800 AVS?

If I was looking to upgrade the carb on your engine, Doug....the obvious choice would be a Proform 750 double pumper.  ;)

Ron

Ron, you'd recommend a double pumper on a 727 3-speed car?  I put the AVS back on this week after trying the 750 demon again, after fixing the vacuum leaks, and man what a nice difference.  With that demon back on I heard that whistling sound again and hello vacuum leak, as you guys diagnosed about two summers ago.  Maybe the base of the carb is warped or something.  The AVS is running awesome...best carb I've had on this engine so far.

Do people run double pumpers with 727's or just manual trans? 

- Doug








firefighter3931

Sure, no problem running a dp'er with an auto trans....go for it Doug  :icon_smile_big:

68 charger stock hood 440 motor, RPM air Gap intake, edlebrock carb, hood hit top of carb..  Switched to stock intake Holley 4160 carb with 1/2 spacer and hood rubs top of air cleaner.  Be careful !

Purple440

In my '71 Charger the drop base didn't work with the stock hood.  Installed a bulge hood a week ago and it worked with no drop base.  That's a performer RPM intake and an 800 AVS.  It would not work with a drop base on the stock hood.

danmc77

Anybody know if the K&N drop base will make this setup fit under the hood:

Performer RPM
Demon 850
Stock black wrinkle finish filter housing

Right now, with the stock air cleaner on it, it just touches the hood when closed - there's no way I could run it like that.  Will the K&N drop base fit around the 850 Demon w/o issues?


Thanks!!

danmc77

Ok guys, did a little measuring and it looks like a 1.25" drop should work w/ my combo.  The problem is that the only K&N dropped base I can find from Summit is listed as 14" in diameter - the stock base is only 13", while the top black part is 14".  Does anybody happen to have the part number or some insight with this K&N dropped air cleaner base?  Please help.
Thanks!

I have a similar situation, but a different combination. '68, 383, Torker intake, 750 Holley, stock air cleaner (11" ID, 12.5" OD 2.75" H filter). Everything fits now, but I want to add a .5" spacer to help fuel boil and hot start issues. To do that I will need a dropped base, but I can't find one with the right diameter. Everything is 14". Anyone have a part number?
Thanks

1hot68 confirmed that the Ford motorsport 13" dropped air cleaner base works - at least with the combo I have.  It's a 1.25 drop (I think), so if you're only looking to add .5", it should work for you too. 

This is where I bought mine - although, I only used the base.

Thanks for the reply and details. Do you have any pics? Also I didn't mention that mine is an automatic. Any issues with linkage clearance?

It looks like plenty of clearance for the linkage, but I have a 4-speed, so I can't say for certain.  I honestly think you'll be fine.  Either way, I'll get some pics tonight for you.

Hi Guys,

           I just purchased my 1968 Charger, It has a stock 383. I am looking to add some low end power. I was reading the forum and decided I would purchased a Edelbrock rpm performer intake with a Holley 650 double pumper carb. I removed the old stock intake and realized that the Edelbrock wouldn't fit with the air condition brackets. I hate to loose the air condition but if it has to go, what can I do. I just know I will get more use and enjoyment with the air (my wife and kids) I didnt install the Holley, I kept the old Edelbrock carb on for now. Do they make an adapter for the air or a replacement bracket?

           Thanks Guys
           Mike R

Mike R the 68 A/C stuff was 1 year only and its very difficult to find I went w/ a 69 set up including p/s pump and had no problems w/ my 69 AC set up

Hi Mike,

            Is the AC set up on the 69 different then the 68. Can you send me pictures of your set up. I would love to use this RPM manifold, I just dont want to cut the original bracket.

            Thanks again

Edlebrock carries a 90 degree banjo fitting the fits the AVS, AFB and thert carbs.

I know this is a VERY old topic, but it is exactly what I am trying to figure out

I have a 1969 Dodge Charger 440 and it has what looks to be an EDLEBROCK brand carb on a MOPAR brand high rise intake

The car came with the hood closed and normal looking stock air cleaner, the one that can take the orange tin plate "440 Magnum" on it

The car seemed to have a high idle and when I opened the air cleaner set up, there was no actual paper filter in it at all

I bought the part the auto store  and put it together, and it seems it's too tall and I can't close the hood

It seems like you guys solved this by

* a paper cleaner not as tall...but does this allow air to get around the filter?
OR
* A deeper or drop base bottom plate.....but how can you figure out what fits the rest of the stock top part of the cleaner?

Or do you have to do both?

Any body that has solved this issue, I appreciate the input.

XH29N0G

You have the main points. 

It is possible to get air filters of different (custom)  dimensions. 

It is also possible to get a drop base that works with unsilenced (not dual snorkel) air cleaners. 

There is a ford part number and think that might be mentioned in this thread. 

It is also possible to have too small of an air cleaner that will restrict air flow.

If you go with an aftermarket drop base, there are a number of other options.

Some other points you may already know:  Make sure you to hood close tests with something like putty to make sure you have enough space to accommodate movement of the engine, especially if you have regular engine mounts and the one on the driver's side breaks.
Who in their right mind would say

"The science should not stand in the way of this."? 

Science is just observation and hypothesis.  Policy stands in the way.........

Or maybe it protects us. 

I suppose it depends on the specific case.....

Looks like the part number for the Ford Proform assembly is 302-350.

I may have to go this route too, as I have very little clearance with a Torker intake and the factory unsilenced assembly. It seems to touch the hood on engine torque occasionally......

Only sucks to have to buy the whole assembly, just to get a 13" drop base with 5/8" drop. 13" is that rare I guess. But that may be the price to pay to have that pie tin look under the hood.
