I would think something like the BTR or Surge intakes would be the best for fitment and power throughout the range?
I've got a Vic Jr. with an elbow and have been contemplating making a change as well.
Both of those still have short runners in comparison to an LS6. Both would likely lose power below 6k as well. Not much will compete with an LS6 or Truck intake below 6k for AVG HP between 3-6k rpm. Something like a fast intake are close from 3500 up to 6kish. But they cost way too much and aren't as boost friendly as the LS6. If you aren't' running the motor well out past 6k... No reason for aftermarket intakes IMHO. If you run a "race motor" where you want power from 6-8k.... that's a different story.
It's not a matter of being "better" than the LS6 intake. It's a matter of once you've had a massive fuel leak from an injector due to the intake pillar mount for the rail breaking you can't get bad thoughts out of your head.
I used some jb weld plastic bonder to fix the pillar and made a bracket incorporating a manifold bolt to hold the rail as well. The bracket I made actually held the rail solidly in place without the pillar mount bolt in. I can shake the rail and move the car with it so it's solid, but I'm just not getting bad thoughts out of my head.
I've driven the car it runs great I even got on it hard a few times, but still looking for a good option to replace this intake.
Keep in mind its a 10.6 to 1 compression 377 with cathedral port heads. No lack of low end response. Peak boost near 20 psi and I have timing dropping clear down to 9 as boost comes in then ramping up quick to 18 at my shift point of 7000-7200 rpm.
My biggest beef with the aftermarket intakes is they try to cram a lot of feature in them and don't include everything you need. Things like npt plugs and barb fittings, throttle cable bracket, etc. Of course the fact they are all 4 bolt throttle body and large openings forces you to buy a throttle body as well. So a $700 intake turns into a $1300 ordeal quick. Then I start thinking well if I'm going to invest that much money I need it to fit long term goals so do I make the switch to square ports now etc.
I've got a lot to choose from, but nothing is jumping out and saying this is it right here...
they can all have a fuel hold down that is a little cheezie. aftermarket or stock. i have used quite a few different setups. you might be happier to just make some nice strong brackets and run what you have . my guess is you will second guess the aftermarket stuff as well.

Thats kind of what my thinking is now. With the fuel demands of ethanol on boosted cars I’m surprised there isn’t more attention paid to this. I think for piece of mind I’m going to install a cheap lifeline dual nozzle fire suppression system with a pull lever.
I ended up ordering the Weiand intake. I live in a small town so while I do some stop and go it’s not for extended time periods. Mostly open road driving. Also since I’m on e85 and Procharged I don’t have any iat issues. So hopefully heat soak will not be a major issue for me. Down the road I may go a different route, but for a direct fit and not back ordered for months this seemed like a good option for the price. Might even make a touch more power up top without giving up anything down low.
looks pretty much plug and play except the 4 bolt throttle body will force me to buy a throttle body as well adding to the cost. Not sure if I have room or want to run an adapter.
That’s a great intake, I’ve got it on my 5.3l with the D1X and it seems to breathe nicely. Looks like you went with the Weiand, I’m not familiar with it but it looks to be decent as well.

Thats not why I chose it though. I just wanted something aluminum that I could drop in without buying other parts and that wasn’t back ordered into next year. I got hellcats to race lol.
You might need to setup some kind of drain with all the frost that'll build up on that intake lol. JK.
Maybe I’ll put meth on it too. Iat has been super low up to this point even with the Procharger over spun. Maxed out 4303 on 50 percent ethanol now. Thinking about selling my injectors, pump, and head unit to go bigger while I’m at it lol. F1a-94 and a brushless aeromotive pump might be in my future.

Says the man who didn't want to to buy a 4 bolt TB with an intake upgrade.

Lol absolutely amazing how your mind thinks once your car is down anyway waiting on back ordered products.
if I’m lucky the npt fitting for the hose barb in that weiand right behind the throttle body is an 1/8 npt and I’ll put a small meth nozzle right there just for cooling.
probably not going to change anything else at this time, but I keep changing my mind every day as I wait for the intake lol
Waiting/time = Bad financial decisions to follow!!! Odds are the first path you “were” on is the most sensible. The second and third (don’t kid yourself there is a second and third or more lol), we’ll that’s where it goes sideways.
I’d like to see where this goes, gives me an idea of what the rabbit hole I’m barreling down into may be like.

This is the equivalent of when guys say, "I'm just gonna do a few bolt ons, not looking to make a lot of power" lmao.
My first car was, just wanna make 500whp, now on my second car looking for a 1Kwhp so.....
Oh I hear ya. I need to get the hood repainted on my car. Somehow that has turned into, I might as go ahead and twin turbo it since the hood will be off...🤦♂️
