Only at the peak. It loses low and mid power in wholesale quantities.

If you're not racing at 3-4k rpm then it's ok to lose a little through there.

My 4.10 gear and 5000+stall will take care of low end and midrange tq on a 427.
looks like the sniper will do great with a low lash solid roller shifting around 7500

I'e heard nothing but good things about the LS3 intake with the radius mod did to them. Heard they do as well as some of these aftermarket intakes.

yeah it looks promising. I will be going that route. Using the short version

I returned my LS3 sniper for the LS7 version when I picked up my new engine. My engine combo needs to make real power to at least 7700 - I think it should work well. I'll likely plan to shift 7800-8000rpm.

is this the same as holley low profile? Looks identical just rebadged.
Holley seems to have back order on the sniper low profile until late July.

More than likely, there's a few resellers of the Chinese stuff. Main difference seems to just be Holley's logo stamped into them

Idk...I bought a chinky town version of the ls7 sniper style intake and it was awful. Gonna make a super cool coffee table out of it

yea I thinkI'll wait for the sniper

The Sniper is Chinese too, so don't think it will be superb quality

Other than your post stevie not many other complaints that I see for the price

Maybe most had lower expectations, or simply didnt look closely enough at them ?

But I do agree, for the money they do still represent decent value. But it cannot be ignored that the quality is seriously lacking.. Port alignment on mine was terrible ( cathedrals )....but how many stick a bore scope inside the manifold to look ? Probably few.

The rubber o-ring seals provided are poor, but I did use them and I do believe they will seal. But they are nowhere near OEM quality.

And certainly on my fuel rails, on one end of each rail the taper at the end was insufficient for the o-ring fitting. So upon tightening it destroyed the o-ring. Now it did remain squashed enough to prevent leaks ok but when I removed everything again, the o-ring was not in any way usable again. That's potentially a serious issue which long term could and probably would result in leaks.
For refitting I tried a 0.5mm thinner o-ring and this seemed to fit much better and so far no leaks. But the other end was fine with the supplied o-rings which are correct for the -8 fittings.

And then there is the noise...the sound transmitted via the thing sheet metal lid of the intake really is terrible. Of course when driving, inside the car etc etc I wont hear this. But with the hood open and engine idling it really is shocking. That again is a quality issue

But I will use it for now, it gives me a good baseline as to what height of such intake will fit my car etc should I decide on a proper one later and as to whether it will genuinely help me in the 7k+ range without spending a fortune to find out.
And yes they do still look cool.

But be under no illusions about the quality even if they are very cheap. Although how anyone can fabricate and supply all the parts even at the level they are for the price, is no joke either. Without doubt there is a lot of work in fabbing these things.
