Just purchased an aluminum 3.5 cyclone lower intake manifold. I have been a little concerned about mounting an entire supercharger system to the stock plastic lower intake so this should alleviate those concerns. Another benefit to this intake manifold is that I can now relocate the water neck allowing me to gain access to the main accessory belt drive for use with driving the supercharger.
Edit: Well unfortunately that idea is gone... It looks as though the bolt pattern of the intakes are different which means it will not fit the 3.7. Damn...
Edit 2: Looks as though a 2015 3.5 composite manifold has the updated bolt pattern and the relocated water outlet. Will not get me the aluminum but will get me the relocated water neck.

Definitely open minded towards all projects but why a roots-style that was used on a push-rod L67 from the 90's versus doing the Coyote swap or Procharger? My guess is to keep the price underneath the cost of a Procharger? I think hidden R&D costs might creep up on you there. Packaging and hood clearance might be a concern (for those who don't want an even taller hood). Turbo is another good option where you can emulate v8 torque but I can see why you don't want to go turbo as progress for that is still in the early stages for reliable DD. If money isn't an issue I would just use a Coyote with the F150 plenum (which looked like your original plan) if reliable torque is what you're looking for. Though if you are set on it and want to do something different do it up. 
Either way definitely find a goal and stick to it or you'll have a perpetual project (been there done that).:headbonk:

I agree with the perpetual project.... I have had so many ideas for what I wanted to do to my car for awhile now and I am trying to settle on one idea and move forward. Basically I want something unique which this project would certainly classify as and I have always wanted that eaton supercharger whine...Definitely open minded towards all projects but why a roots-style that was used on a push-rod L67 from the 90's versus doing the Coyote swap or Procharger?

The coyote swap was the direction I was going towards but after pricing out everything required (its the little parts that add up) it would have been about as expensive as the procharger system and I would have ended up with basically a stock coyote. The procharger system is great but I have just never liked centrifugal superchargers (how they sound, how the deliver boost, etc...)
Turbo options are still early in development and are very involved installs. Oil return lines is what killed that idea since I would have to pull the engine (or pretty damn close) in order to remove the oil pan to drill return line holes. A scavenge pump is not worth it either as a decent one that is not crazy loud is almost $400 and there would be no guarantee that it will continue to work for a long time.
The eaton superchargers are a tried and true method of boost and the GM M90 is by far the most abundant and cheap. I would prefer something like a roush M90 but those are very rare and will have to have extensive modifications in order to decrease its height. Twin screws would also be an option if they were not so expensive for not as much benefit as people might think. There is a benefit to using them yes but I do not think that benefit merits a 10 fold price increase.
If I can sort out the lower intake manifold I believe I will be moving forward with the project. Either way I am still getting the hood as I have always loved that hood! It is not much higher if at all then the stock hood if you take into account the ridges on the stock hood. What it does do is remove the internal bracing and raise the center up to the OEM ridge height which should create the space where I need it without raising the entire hood surface.

They do sound good, there's no denying that. I agree with you on the state of turbo-progress for the time being. Definitely too involved considering the similarities of the 3.5 and 3.7. While there are a couple of quick boosted 3.7s, I haven't been impressed with the performance in some of the videos I've seen them in considering the money and time spent. Supercharging seems to be the balance king for these engines so far. Well if you can make a kit that has ease of install like that video good on-ya. There is also the M62 which is the baby version of the M90 used on the Nissan VG33ER.

You can pulley the M90 gen5 SC off the grand prixs down to like 2.8 without turning the snout.
I had a cammed e85 gen5 2.8 pulley GTP that made 330whp and 400wtq in a 1999 GTP coupe.
Them Gen5s sound badass pullied down to 2.8
I got sick of the 4T65glass transmissions and decided to buy my 16 5.0.
Anyone see a kit for these on the new 3.7 V6?

makes kits to use the MP112s of TVS blowers off the gt500s on the coyotes and modular 4.6s too.

Really now, almost the same price as a prochager. I would have thought it would have been more expensive. I was thinking that my budget for prochager is about 8k-10k. If that is more or less enough I might just do that stock motor et al...
BTW yes Whipple whine is better than prochager whine. But both sound good to me.

If you went with an F150 coyote and did the isntall yourself the price would be around the $4.5-5k mark. That is also not including any suspension mods and brakes that would likely be not required but useful. Another reason why I decided against this is that I actually test drove a GT and wasn't all that impressed.... It felt heavy on the nose and not that much more powerful than the 6 in everyday driving. Now when you stomp on it you certainly feel a difference but I want that low end power.
I hope to complete this setup for $2-3k including the hood.

Your better off with a direct fit procharger kit. I made 360 rwtq and 454 rwhp. Thats more then you will get from an m90 and it will run 100 degrees cooler and be very reliable.

Funny, I was daydreaming about this exact concept just yesterday 
Although used M90's are cheap enough, I'm not certain it has the airflow capacity to make a big enough difference on our 3.7 to be worth the cost and effort of such a project. I'm not trying to talk the OP out of this, just mentioning my own opinion on the subject, and I may be wrong on the airflow issue so if someone knows for a fact that the M90 can make decent boost on the 3.7 above 3k rpm (which is where these engines really wake up) I'd like to hear about it.
Now, the M112 from the '03 Cobra was pushing enough air through the intercooler to make 390hp from a 4.6L that was rated at 300hp in NA form, which seems pretty well suited for boosting our 300hp V6, and I've seen it for sale fairly cheap as well, but without knowing the dimensions on that blower I can only guess if it can be made to fit.
I like the idea of swapping in a complete 3.5 Ecoboost engine, even with a horribly restrictive exhaust, undersized turbos and the smallest exhaust manifolds I've seen it still manages 420 ft lb factory stock, so there's a lot of potential waiting to be tapped here.
Then I figured as long as I'm daydreaming, if I did a V8 swap I'd like to go with the 5.8L aluminum block, top it with street ported coyote heads and Comp Cams CR cam set then use the MMR gen-x timing set and a sheet metal intake manifold to run it off a 2015 coyote PCM. I figure this should make some serious low end grunt, only issue is the $20k to build it! LOL
