Yes, I tried using a stock 5.7 intake. I saw Holley has a low profile Sniper for LS coming out so I thought I would ask.
It would be nice to run a flat hood.

I can build you an intake
I just need to know the dimensions I'm going to need to work with

When you say a stock 5.7 intake. Are u saying it would not fit??
And if not by how much

Yes, it would not fit. I forgot by how much as it was a while ago when I first mocked everything up. I will get some measurements.

I am in the middle of design on a billet, low profile version that will use LS style throttle body. There will be two versions, low profile for boosted applications and a mid rise version with runner length, taper and size that is appropriate for 420" ish engines making peak numbers between 7000 and 7500. Flow designed using CFD (Computational Flow Diagnostics) within Solidworks 3d software.

I'm surprised that there is such a lack of manifold choices at this point for Gen 3. Will see if made in the USA is even possible, but making no commitment to that for now. Will be very nice and not $4800 like the other billet offering.

Not trying to hijack Steves post. I believe the more choices the better for these engines. They are the future of our Mopar hot rods.

The lack of options has to do with the lack of market,
but as more and more Cars and older body Swaps happen the more the market will open up.
Truck guys are limited to options because of Cab over hang into the engine bay.
Height is the big issue on after market intakes...but I have faith in you guys.
A taller deck block would be nice down the road, but the width of the G3 will hinder that

Another thing I would like to point out is, keep in mind most of the "builds" that happen are in the 370-400 inch area right now,
5.7 blocks ae still the major base block for many builds.

Again I and many others appreciate the R&D and effort your both putting in to this.

Is the overall height going to be taller than the 6.1 intake?

Never mind, I just went back up and saw that it will mimic the height of the 6.1.

Looking good, Looking forward to seeing the end product

Looks cool, what is the reason for having no taper in the runners?

Just curious, why is there a deep tapered belly below the inlet of the runners? All intakes that I have seen have plenum above the inlet of the runners? Am I missing something here? Not criticizing, just learning.
Keep at it.
Thanks

Im gonna guess the plenum is like that so the throttle body can go in the stock location

there won't be enough volume above the runner if the top is put on right there.

there is no taper to the runners because the runners are stock material that was cut to length. 5-10 degree taper is usually what you need to an engine like this. the runners are the hardest part. making the flanges is easy.

looks good for a first attempt. I'd be curious as to how well it works. definitely a higher rpm intake than the factory one with the short runners.

In a boosted application the taper probably means little. NA the taper determines at what rpm torque and hp are created along with the runner length. That's why Pro Stock racers keep their manifolds covered.

Google "intake runner taper" or even "efi intake runner taper" and you'll get quite a few links to discussions on the subject.

Long story short, the three basic tuning parameters of an intake manifold are runner length, runner taper, and plenum volume.

not knocking your build, but I've spent a fair amount of time researching and running design simulations on various intake designs and have cnc machined some runners for viper engines over the years. I applaud your effort in trying something new and I hope it works out well.

just giving an opinion that the runners seem to too tall and straight and there isn't enough plenum above them to draw air straight it. maybe its the angle of the pic. its also the reason the factory runs curved runners. its easier to package length in an arc. obviously not so easy to do in a weldment with a one off like you're doing.

also tapering the runners add a "ram" effect to the incoming air. as air is pushed through progressively smaller openings its sped up and this aids in fuel mixing. if you have a pipe like you;ve built you create a laminar edge along the surface of the runner of slow moving air. having a taper minimizes this. also you create a step at the head as the shape of the port changes, this creates an orifice which also creates a pressure drop. lots of engineering hours go into designing these things for optimum use. however there are always compromises, some of them are available materials so you build the best you can. again I applaud your work. I hope it works well.

if you'd like more info i'd be happy to help.
