In-line Hemi Carbs & Linkages - 11/14/05 12:58 AM
I recently purchased a crate 426 HEMI to drop in my 69 RR 4 sp. I want to install dual quad inline 4bbl carbs. Car has hood air grabber so height is important for the air grabber breather baseplate to make a seal.
I'm going to purchase a dual quad inline intake from Mopar Performance which they say is the correct factory height when installed on a Hemi.
I need advice as to what front & rear carbs (brand & #'s) to run with this set-up so I will maintain correct height and also the airgrabber breather baseplate openings will fit on top of carbs.
Would also appreciate inline linkage & fuel hookup make & model #.

That`s going to be a little tricky because the original hemi carbs had a 4-7/8" air horn and all the aftermarket stuff has the holley size 5-1/8" but the originals were a little taller so you could get someone to machine some cone shaped adapters. I think I heard somewhere that someone was making baseplates to match the later "eddy" style carbs.

www.forhemisonly.com has the baseplate and linkage that you need, but I think it's for the Stage V dual quad intake. Ask Tim if it will work with the MP intake.

I haven't worked with the MP dual carb inline manifold but I've built some linkage kits for the Stage V manifold. My guess is that they are pretty similiar but your results may vary. Give Bob Mazzolini Racing a call, I know he has these linkage kits in stock.

The new Edelbrock/Carter AFBs in either 600 or 750 CFM size seem to work well - size depends on the rest of the combo, of course. You might consider modifying an aftermarket baseplate to fit the larger air horns on the new carbs. I think there's also someone selling ring adapters for use with the OEM (smaller, as noted previously) air filter baseplate.

good timing on this thread .
there is an add for a member that modifies the original baseplates , the big difference between the stagV and what MP sells , i am pretty sure its the same intake ?? , is to get the holleys in line the carb mounting pads had to be moved further apart so using an adaptor ring is not an option .

I'm pretty sure the Stage V and the MP manifold are two totally different animals. The MP one appears to be a dual plane setup while the Stage V is a single plane. I've had the Stage V one in my hands but I've only seen the MP one in the catalog.

Re: In-line Hemi Carbs & Linkages - 11/18/05 05:05 AM
JohnRR those intakes are night and day.The Stage V is a performance intake and will out horse power the MP intake by a quite a bit.For Hemis Only use to have some figures on their web site to compare most intakes and carbs but I am not sure what is on their Web site right at the present time.
If you plan on running a stock motor compare a factory intake and a MP intake for price,if your running some cam and headers go with the Stage V stuff and use the Carters or Hol. but with the Stage V intake your carbs are spaced farther apart than stock.Now the single four intake you get with a crate motor Hemi is just there on top of the motor so nothing can get into the motor.I have run this intake and its not a very good performance intake,could be ok on a stock motor.
I have also got a Vanke intake and the Stage V intake out performs it also by a lot.

I have the Stage V intake and it's a beauty. I haven't seen the MP dual 4 intake in the flesh but it is a two plane where the Stage V is a single plane. I think the carb spacing on both the Stage V and the MP dual may be the same though. I know I couldnt run the jet block on my front 1850 Holley because there wasn't enough room on the Stage V.

You can run a jet plate in the secondary.

thanks guys , sorry for the confusion on the intakes , from the outside they look pretty similar , but yes from the pictures i have seen the MP manifold is a dual plane , looks like a modified , streched verison of the stock with the Vanke mods done to it ?????

Re: In-line Hemi Carbs & Linkages - 11/18/05 06:49 PM
VP: Are those carb spacers offset? My 1850's are that close without the jet block, I have them bolted to the manifold though as I need them low to make my stock chrome dome top work on top of everything and not hit the hood on my 66.

wasn't the orignal setup progressive ??? the 2 setups in the pics look like it pulls on both carbs at the same time ?

John,
The new Mopar 2x4 intake for Holleys is the same as the old "Marine Intake" that Mopar made for drag boats in the late 60's early 70's. It is an inline 2x4 setup and you are correct, the carb spacing is different than the OEM 2x4 Street Hemi intakes that run the Carter AFB's.
In addition as previously mentioned the OEM Base plates will need to be modified to work with the new Mopar Intake & Holley Carbs.
Last, the OEM street hemi's did have a progressive linkage for the carbs as you stated in a later post.

I used this Edelbrock linkage on this car. Edelbrock carbs on a stock 66 manifold. This linkage can be set up for progressive or non-progressive. Sorry, don't have a closer pic. Worked really well. I set it as progressive.

Re: In-line Hemi Carbs & Linkages - 11/20/05 07:32 AM
I have the marine intake on my challenger. I made my base plate out of a piece of 1/4" aluminum and had it powder coated black. I am runnig 2 of the 450cfm mechanical secondary hollies. I put a 50cc pump on the back carb. I used the 20 dollar Mr. Gasket progressive linkage that Jeg's sells with no problem. I have the rear carb set up as the lead carb. I had to make an adapter bracket out of 1/4" square tubing that bolts to the carb studs so the lid holes will line up. I am running a chrome six pack style lid. (for a hundred bucks, you can't beat it.) It may be a little under carbed for all out HP, but iit responds like it is fuel injected. My girlfriend loves to drive it. I really built this car to get her out of my road runner.
She used to drive that all of the time. If anyone needs to see some pics, let me know. I'll try to post some.

I used the same set up as Moparmikes picture.. It is a stock 66 manifold and 750 eddy carbs. --75's butterflies are a bit close to manifold bores.. I double gasketed to clear.
The linkage can be set iether way.

Re: In-line Hemi Carbs & Linkages - 11/20/05 04:50 PM
I bought a repoduced polished aluminum air cleaner from an add in Mopar collectors guide. He makes both size bases.. one for the old carters and one for the new Eddy carbs. it all seems to fit real good.

another dumb question , how much taller is the stage 5 vs the stock ? or is it the same height ?
also anyone running dual holleys with vac secondaries and progressive linkage ???
i just bought a stage 5 intake off the 'bag and my bee has a ramcharger setup .

John: I have the Stage V with dual 1850's and I have a stock intake with Carters and the airhorns on the Stage V setup is 1 inch higher than the stock setup. With the Ramcharger aircleaner you could drop it down at least 1/2 inch when you modify it to fit the Stage V carb spacing. I am hooking the carbs direct because it is a single plane intake. Although I suppose progressive linkage could work.
You'll like that intake, I think it is the only intake I've owned that I could check the head port alignment by simply looking through the carb bores at the head ports.

nope , as much as i malign ebarf , when its necessary and its always necessary , if i see a good deal i'll buy it . of course i paid LESS for it than buying it from a retailer , i think , paid $495 and its NEW ??? , and its local so i don't have to pay shipping .

thanks sheldon , i was thinking about this yesterday , the carbs are spaced further apart so how do you modify the lid ? or do you have to use some funky bent hold down studs ?
does anyone sell a base modified since i don't have one and what does making it a drop base do to the distance between the lid and the carb air horns ? or am i looking at removing the choke horns for best performance ???
might have to ditch this intake and buy the MP one ??? or wait for the stock spacing repop ???

Ben Snobar sells bases to fit these intakes. They are kinda expensive, I think about $800.00. That is why I made my own. Oh well, welcome to hemiville.

Re: In-line Hemi Carbs & Linkages - 11/25/05 08:39 PM
The 1850 carbs have vac secondaries. With a single plan manifold I think you'll want to run the carbs 1:1 and not progressive. Shoot me a PM on the linkage kit if you're interested.
I don't know anything about the base plate or how it will fit with the hood. My guess is that you'll need to perform some surgery.

You can use those air cleaner adapter rings but they set the air cleaner up about 1/2". Can't see them with the cleaner installed but only cost a few bucks compaired to a few hundred bucks for a repo base.

mark i think we went over this before , NOT happening , the carbs are further apart , the only setup that the adaptor rings will work with is a factory stock 66-71 inline intake with replacement carter or eddy carbs .
i'll have to butcher an air cleaner to use either the stage 5 intake or the new MP intake .

Re: In-line Hemi Carbs & Linkages - 11/25/05 10:42 PM
I'll measure it up for you John. I never fully figured out the Ramcharger style setup as I changed cars to a 66 before I ran the setup on my 71. On my 66 the Holley float bowls are too long and you cannot use the stock filter in any way, so I'm rigging up some of those goofy short foam element Edelbrock air cleaners under the stock chrome dome. I think you may be able to mill a bit off the stage V's carb mounting area to bring everything down a bit as well.
Okay here we go:
Stage V carb center to center 8.5"
Original center to center 6 5/8"
Stage V with 1850 Holley end to end 17 3/8"
Stock ramcharger filter end to end inside 17 1/4"
Stock hemi AFB bottom to air horn 4"
Holley 1850 bottom to air horn 3 1/4"
Stage V and Holley front carb bottom of manifold to air horn 8"
Stock intake and hemi AFB's front carb bottom of manifold to air horn 8 3/4"
In a nutshell the Holley's aren't going to work with the stock air filter very well as they are too long.
I would check the newstyle AFB's as they will be lower than the small top hemi ones are, you should be able to make the Ramcharger work with the new AFB's, a modified baseplate and some offset air cleaner studs.

John. I fabbed a bracket that bolts down to the carbs and has an offset stud that lines up so you can use a six pack lid. Works well. Let me know if you want me to post a pic.

DID YOU CHECK HERE?
Check with Classic Haulage in Canada. He advertises in MCG and makes a lot of different Hemi bases.
He also makes aluminum tops that look like the original 66-68 but they fit the Edel. carbs, he may make other tops as well.

Re: In-line Hemi Carbs & Linkages - 12/06/05 02:29 PM
I just spoke with Tim Banning of For Hemis Only. He makes the baseplate for the Stage V with dual Eddy carbs. He also makes a Six Pack lid and has an offset stud for the rear carb that makes everything line up. You can buy everything from him.
I thought the Six Pack and Hemi lids were the same, but I guess they're different. If you have an original Hemi lid, or buy a reproduction Hemi lid (also available from
www.forhemisonly.com), Tim has a guy who makes an adapter for the carb studs that works with the Hemi lid. The price for that pieces isn't too hateful considering it's a "Hemi" part.
