4 Barrel Intake under shaker on 71 Cuda

[Steve Blair]

Good morning everyone,
I have a 71 Cuda clone with a 440 and 4 barrel shaker assemble that has a CH4B intake, the problem I'm having is the intake is about an inch too tall for the shaker to fit under the hood. Does anyone know if the Wiend Action Plus would fit since it's supposed to mimic the height of a factory 4 barrel intake (I do have a factory 4 barrel intake but from what I read it has poor performance).

Not sure if this will help, but there are a couple different 4-bbl shaker bases. The throat on a 383 baseplate is about 1/2” deeper than the 340/440 base. At least that’s correct for original parts. Not sure on repros.

The OEM stock intake manifolds do an excellent job placing the carb at the correct height and position for the shaker setup. When we deviate from that setup, things can get complicated.

I'd be surprised if the Wiend intake adds more than 10 HP. You may find the OEM intake a worthwhile trade to get the shaker working correctly.

I predict the simplest path is going back the to the OEM intake.

If the below link info is true, seems the manifold is not the only issue.

The article I read compared a number of intakes (with the stock intake being one of them), according to the article the stock intake developed about 50 hp less than the Wiend Action Plus (which was far from the best). Since I had my engine on the dyno with a Edelbrock RPM which was better than the Wiend Action Plus (but way too tall for the shaker hood) I hate to go back to stock when the Wiend is supposed to be very close to the height of the stock 4 barrel manifold but develops greater hp and torque. The shaker assembly and hood was purchased through Year One a number of years ago for a 440 so I would hope its correct. I guess I will compare the height of the stock manifold to the CH4B after I remove it just to see what the difference is and go from there. Thanks for the feedback, as always you guys are a great help!

I thought I would provide an update on the shaker hood, turns out I didn't understand the hood needed to be pushed down to compress the seal on the shaker so after I adjusted the hood so it was centered on the hood pins and lowered the back of the hood it fit with the CH4B intake just fine (I just had to compress the seal some). Thanks for the input, I will post some pictures of the car in the next day or two...

Hello all. I need 911 kinda help!!! I have similar issues. I have a 72 Cuda 440 beast of a build that taken 6yrs to complete. It dyno at 655 hp/691 ft tq and nosed over at 5400rpm, Cam is 291 duration 600 lift, 10:1 flattop pistons, trickflow(TF)240 heads & TF high rise single plane intake and the list goes on. My issue is I always wanted a shaker so I started buy parts and now I've learned the intake is to high. Which intake should I use and not loose HP and Tq but will work for a shake fiber glass hood? Thanks in advance.

It can be made to work with some custom mods. I was able to custom make my Shaker hood opening, base and scoop to clear a tunnel ram with two 1050 Dominator carbs.

OK, can you elaborate or send some pic's? I don't have that talent. I know enough to be dangerous or get me in some serious trouble.

Mine is alittle over kill. However, so is the rest of my car. I stretched the hood opening, the base and the scoop 2-1/2" longer. Then raised the scoop height 4" and opened up the scoops nostrils 2-1/2" taller.

Just look at his car! 528 Hemi is not your hop in and go cross country car, but don't race stop light to stop light!!

For simplicity, you will have a hard time betting the Holley Strip Dominator! Less modifications!

Lol. I could jump in it and drive to your house right now. It's a pump gas engine. I drive it all over on the street. It would just take a few stops for gas along the way....

Holly Cow you do have some kinda talent. Yea, I wouldn't know where to begin. It's been 45yrs since I helped glass an old boat and that ain't no boat. I guess I'll try and find an intake and maybe it will fit. Thanks you, Sir.

They are not that uncommon. But FZYI, the last two 1970 440-4 numbers-correct intakes I've bought, I paid more for shipping than I did for the intakes.

It's crazy how many I have just scraped over the years....
