Is he planning to run the cam that comes in the B15? Is the guy's goal to hit a dyno number mostly?

Plans to run it as it came in the crate and it must be responsive on the street. It's primarily a street car (not a DD) that will see the track about twice a month and he wants to run a consistent 5.80 in the 1/8-mile without wringing it's neck or having to tear it apart every so often. It's a 3800lb car and the TT LSX will be replacing a big block Chrysler. Shhh, don't tell the MOPAR guys, they'll have a cow.

if your looking for torque and peak power in the 6-6500 range you might want to think about a fast or msd intake
Is the BTR and Shearer intakes considered a short runner intake?
With the Shearer using a Holley High Ram base I would have thought it would be a long runner.

the btr definitely and the shearer fab one I forgot is made on the hi ram so that would be a long runner but at almost 10” tall might still cause some hood clearance issues

the stock ls3 is not a bad intake if your not looking to make every last bit of power

Not to thread hijack but I'm currently running a Victor Jr. with a fabricated elbow on my current setup and have been considering the aforementioned intakes because I've read the Vic. Jr./Elbow setup doesn't work very well on LS turbo setups.
Have you seen that as well?
Would the BTR or Shearer be a better option?

I don’t have any first hand experience with it but I’ve herd they were supposed to have bad cylinder distribution but there’s also a lot of very fast ls cars that still use carb style intakes with the elbow

The lod intake is a short runner intake

I've read the same thing regarding "poor distribution" but I'm wondering if that's in a max effort, high rpm (7,500rpm+) application.
I think for my tame application (7,000rpm max, 20 lbs. 1Kwhp) I may not have that issue (if there is an issue) and if you know of guys out there making big power with them then perhaps I'll just leave it alone for now.
The crutch on torque production with the single plane might also be helpful for me in the near term as I dial in the car on a 275 drag radial.

The Edelbrock Pro Flo performs well and fits under a lot of stock hoods, what is this going in, apologies if you already shared that.

No worries John, its going in my 1999 Camaro SS.
Hell the Vic Jr. and elbow required trimming of the cowl where the weather stripping is at, gotta be careful washing the car lol.
I don't want to do a factory style intake so something like the BTR or Surge goes well with the rest of the under hood eye candy.
There may be no choice as I'd have to redo the Davies Craig cooling system as well it looks like.
It may not be worth the hassle if I can just throw a few more psi at it to make up the difference.

I’d love to run a 376 LSX 15B with a Magnuson 2650 and a T56 magnum for the street . That would be a good summer car

Planning to do a test fit this weekend with a mockup engine and hope to determine how much hood clearance we will have. With this LS7 cam, there seems to be no point considering any intake that shines from 5600 to 7600 and I have yet to see a hi-ram that fit under any stock hood. Cutting the hood, hood scoops, etc, is not an option. My choice would be a Pro-flo since I have experience with it on my 6.0L in the past and it now being on a 370. Dimensions say it is 9.68" at the rear and 9.2" at the front. From what I've read, the hi-ram is 11+", at the front, making it even worse. Push comes to shove, we'll use the stock intake and run an extra psi or 2.

I think the Pro-Flo is one of those intake anomalies that performs really well but looks kinda ugly so it doesn't get much play kinda like my first girlfriend lmao.
Would it make sense to go with the intake you'll need in the future then switch cam or are these parts already on hand?

He only has the engine and a TH400 coming. The engine will initially be used as is. Nothing else is decided on yet.

Call me weird, but I prefer the looks of this over the "goose neck" hi-ram.

I like how both of them look. I help Holley out on some stuff so I run their stuff, but if I did a Pro Flow I could run a stock style SS hood... which would be bitching.

Okay, that looks really good in black, I'd run that for sure.
That will fit under the cowl of a 4th gen camaro?
