Shaker hood and aftermarket intake manifold?

Can anyone tell me what (if any) aftermarket single 4 barrel intake manifolds will work on a 440 and fit OK w/ a shaker hood?

Car in question is a '70 challenger R/T, U code (440-4). Original motor and trans are long gone.
Wondering if we can put something like an Edelbrock CH4B or similar intake on it and have the shaker assembly still fit?
Engine and trans not in the car yet, so can't test fit anything.

I tried searching this topic and came up with nothing.

There is nothing on the market that can adapt to aftermarket intakes unless that intake is same as stock height. The carb will be too high in almost every case.

You will have to fabricate an adapter air horn to go from shaker baseplate to carb. What I did was measure the shaker bubble grille lower surface to the floor. Then measure hood trim ring to carb. Then figure out what height was needed between them. I found an edelbrock drop base that was very close to what I needed. I then cut the baseplate air horn out, then modified the edelbrock to fit in its place, riveted it. I was working on a 340 motor, so a 440 may need spacers to get the height where you need. And a 440 has different shaker brackets so you need to look at those to see fitment modifications too.

I only have pictures of the first two steps.

the CH4B should be super close to a stock intake height.
however, i can't tell you how much wiggle room you have, because all cars built are not even close to each other tolerance wise.

Can't for the life of me remember which intake but remember an article that stated one aluminum intake was basically identical to a stock intake. Maybe someone else will remember.

Thanks yall. I know it needs to be the same or real close to the factory manifold height, but not sure if there's much "wiggle room" for a slightly taller manifold.

The Edelbrock CH4B and Performer should be close to stock height, but they are a little taller I believe. The Mopar M1 dual plane is stock height, but hard to find since they aren't made anymore.

For an intake that is close to stock height, you can shim the K member down to get more clearance. I've done it several times.

I have an Indy intake and Dominator carb under my Shaker. I also used a drop base fabbed into the Shaker carb base and dropped the K to get it all under. Also ended up making a new higher bulge in the air cleaner lid since the carb is now up inside the Shaker bonnet.

You might consider installing the engine without an intake and then setting a stock intake on the engine and measuring that carb flange height. I use a straight level board that sets on the fender wells. From that, you have a way to measure how much you will need to 'adjust' for your new intake.

And as a last resort, you can have the carb flange on your new intake milled down to help with the fit. I have done that before, too.

Chip, I calculate the wiggle room is just under 3/4". I'm running Indy EZ heads on an RB with an aluminum Edelbrock six pack intake, and the factory shaker parts. My shaker sits up proud of the stock position by just over 1/2". It all still works together, but I do have a few rub marks from the hood's trim ring studs on the bubble.

Here's a picture of it. In my opinion, it sure makes the stock position look too low after seeing it sitting up higher.

I agree! I think yours looks the way it ought to!
I guess I need to measure some intakes and see what the difference is.

This is on a friend's car and I know he doesn't want to lower the K frame. The car is going back together now and the suspension is done.

Also, depending on what motor mounts you use, you may need more or less "wiggle room" gap at the hood.

Stock rubber mounts generally move more than aftermarket or solid mounts. More movement needs more clearance...

Chip mine is also a little over 1/2 higher than stock and also think it looks better. I agree 3/4 is where it will start to rub.

Good info on the motor mounts on an above post. I use Mighty Mounts, which fit well and are the same thickness as stock, but I still chain the motor, as those poor little mounts take a lot of abuse with a stroker motor.

Good point yall, thanks! I'm not sure what mounts he's going to use...most likely stock replacement stuff.

i'm pretty sure the CH4B is around 3/8-7/16" taller than the iron original. i had an M1, but sold it. if i can dig out my CH4B, i can measure it and be sure.

If you have the stock valve covers on your engine and an available stock 4 barrel intake, the following pics may help you compare carb heights on a few various intakes. I took these pics a few years ago but never did get a measurement on a stock cast iron 4 barrel. These pics are all of a 440 and include a stock aluminum 6 pack, an edelbrock performer rpm, an edelbrock performer, a 2836150 aluminum intake, and an older "over the counter" mopar aluminum intake. All measurements taken from carb surface to valve cover. jess

Last one...

2836150 and the OTC intake

I believe Hughes has the intake manifold flange heights listed in their manifold flow tech pages. They measure from the front China Rail.

Chip, with stock motor mounts, it seems wise to me to run some sort of a movement limiting chain, strap or something to protect the shaker from being smashed when the stock driver's side mount lets go. It's pretty much only a matter of time until a stock mount tears in half, even with a stock 440 motor.

jt440...thanks, those measurements are great. The 2836150 intake is an Edelbrock CH4B that someone has ground off the edelbrock logo.

The "OTC" intake you have is the Mopar M1 dual plane. It's supposed to be an aluminum copy of the cast iron '71-'72 manifold w/ a few minor changes. I had one years ago, but sold it. Wish I'd held onto it since they're no longer made.

jbc426...I agree about the torque strap. I have one of the Schumacher straps on my dad's road runner and it works great. I'll see if he will get one of those b/c I know he won't be crazy about a chain or anything that looks too "non factory" on the car.

Those measurements for the flange height from the China Rail are on Hughes website. Look at the Intake manifolds for RB's as if you wanted to buy one on his page. They show the measurements for all the manifolds they carry.

Just anecdotal input, while not a Shaker, we put a Holley Street Dominator intake on my buddies 69 RR with an RB motor. It has the factory Air Grabber hood and it was a tight fit with just a little trimming of the base plate neck. It is a much better performance intake than the old edelbrock dual planes and probably no higher.

I have always had good luck with the Holley Street Dominator intakes, too.

I used a Weiand dual plane intake on a E body with shaker. 440 engine. It fit fine. Don't know if these intakes are still available new. If not I am sure a used one can be located.

In order of height greater than the factory cast iron 4 bbl intake

CH4B & Weiand - 0.3-0.4"
Performer - 0.5"
Torker II - 0.8"
SD - 0.9"
Indy 2D & RPM - 1.5"

You will be fine with a CH4B

i found my CH4B intake, but it's buried behind "a little stuff". from what i could see, it has a 28something part number cast, plus the CH4B cast number. the 2836150 intake pictured is probably the CH4B intake, as it looks identical to mine without the "eldebrock" [] casting numbers.
BSB67, thank you ! you confirmed my old mind's recollection of 3/8-7/16" height difference of the CH4B.

Ditch the carb and go with an EFI throttle body.
