Hi Cody,
I hope you are well. I'm really surprised that there isn't more info on this topic. It's like crickets out there no one knows. Maybe someone here will have an idea.
Here are some pics.
Love the videos by the way.

WOW! That's looking really good! Going to be a super sweet ride when you get it done! :yes:
Hoping Neil will know a little about the 340 shaker intakes. I think the 340 Shaker is the most rare. :notsure: Lots of people do Hemi & 440 Shakers, but not many 340's?
Wow, that's going to be a sweet ride when done. Sorry, but I don't know the answer to your question but I know there are 2 different shaker base heights that may allow you more intake height. The different isn't much, but could be just enough. Good luck. :bradsthumb:

This is a carb off a 71 340 Cuda. It might give you some idea of the height needed to fit the carb.
Awesome thanks Cody.
Carb height will not change , Carter & Holley seemed to use the same std height as is used today as well .
I would measure a stock intake from the end rail to carb flange to get a baseline height & go from there , one of the best intakes for the 340 was the LD340 & this should be good height for the shaker , the factory intake was also a very good intke but heavy but for a number of years it was reproduced in alum but has been replaed with the Eddy rpm through Mopar now which is taller , the air gap is much taller & is a no go .
Do not go with the Mopar M1 intake as she is very tall.
She is beautiful but tall. heh
Hi Guys,
Thanks for the response. As I said I would use the LD34 in a heartbeat but the PO removed the center plenum. Changing it from a dual plane to a single plane. I was worried that would change the performance band from the low end and go to the top end on mildly build 340. What are your opinions on that? If you say I won't notice a difference then I won't make the change. Take at the look at the pics above of the LD340. Thanks guys.
Sorry they weren't in this post here they are.
If it's already installed on the engine, then run it and see how you like it. It's a really good intake and you might love the way it works. Plus that gives you a starting point to test your shaker set up and hood. If it doesn't fit or you don't like the intake, you'll have a good starting point. :alan2cents:
No it's not installed yet. I'm not going to install it until after the engine is in the car. Makes no sense to install it out of the car only to have to remove it if it's the wrong height. This way I can test fit it a little better.
Why not weld or JB weld a new divider? :notsure:
I wouldn't fully weld just tack weld and then seal.
I'd say just run it as the plenum is still divided alas not like before. In this config it still will not operate like a single plane.
You got nothing to lose.
I've never used JB Weld. If I used it to put the plate in would the fuel overtime eat away at it? I would hate for it to end up in the cylinders. My welder doesn't weld aluminum. Is there other products out there that would be better in this situation? Thanks
I don't have any FC7 spray outs right now, but I'm planning to do some next year. I'll try to remember to do some extras in case anyone wants them. :handshake:
Sorry Cody I didn't make any roll outs of the paint.
:iagree: make a divider but it may work very well without it also , You already have it so try it out first
