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.

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.

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 ?????

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.

Sheldon

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

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.

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.

another pic. Check out the home made throttle cable bracket.

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.

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.
