Sure this must have been asked before, so apologies.
Just browsing the internet and stumbled across these:
Have seen them before, but they look even cheaper than last time I came across them. I know, I know, if it looks to good to be true.....
Just wondering if anyone has any experience of them and if this kind of intake manifold will even fit under the cowl/scuttle on a 4th Gen Fbody?
As I'm in the UK, there is no real choice for intake manifolds here, unless I buy in the USA and ship over. Which is a very expensive process. My 99 z28 still has the factory LS1 style intake and I'd love to find a cost effective way to upgrade.
A very common problem with china sheet metal intakes is the intake to head surface mating angle being wrong. This makes some of them impossible to seal from vacuum leaks. If you get lucky and don't have this problem, they still underperform almost every other possible intake manifold all the way through the usable power curve. Then you will likely have to fabricate custom fuel rail mounting hardware, throttle cable brackets (if not a DBW), and a vacuum block. Also, you will need to get it to know if the fuel injector bungs are mounted angled or straight up and down before getting fuel rails. But they are cheap and look cool.
LS6 with the stock Throttle Body would be budget friendly for the power you'll get out of it.
Really? Where are the budget LS6 manifolds you speak of? Every one I see selling them wants aftermarket intake prices. (genuinely curious, not being an ***).

I ran into this same kind of situation a few months ago when I saw someone asking about buying an "02+ ls6 cam for several hundred dollars. In my mind they were still the $150 budget upgrade from years past. Time does that to all of us, lol.

I think Doorman makes an LS2 intake which is similar to the LS6 in terms of performance. It will work on LS1, LS6, and LS2 engines. Possibly more of them.

That Dorman intake is over $1k on Jegs. Crazy, but true.
the dorman is not as good as factory ls6 and way more money
ive sold a few ls6 in the $500-550 range which is a lot cheaper than new dorman or fast, and cheaper than used FAST as well as people think theyre worth $850 used lol
You'd think with today's technology, 3D printed intakes would have happened by now. But yeah, intake prices are ridiculous. That Dorman one should have stayed cheap, but companies have to be greedy. IIRC, that intake was designed from the original FAST tooling, which is why it performs so well.
I don't understand why guys aren't 3d printing badass intakes for peanuts at this point.
For hobbyists the size is the biggest factor. Most "home" grade printers capable of maintaining the temps needed for the high temp plastics such as nylon or PC only go up to about 200mmx200mm. There are quite a few other factors that make it difficult (but certainly not impossible) to do on a home budget setup. And of course mass production is much better done with injection molding, so 3d printing an intake is pretty much going to be stuck to the realm of hobbyists. I am still thinking about trying to print ITBs with motorcycle carbs for my Dad's old GMC 305 v6, since it has no water ports in the intake.

I'm actually surprised more molded plastic manifolds aren't around. I doubt FAST has a lock on that technology.
Dorman shot themselves in the foot by raping the performance intake market with the LS2 intake.
They can't cost that much to make with modern production methods.
What I want to see? Someone manufacturing a large plenum cross flow longer runner sheet metal intake, something akin to the old Accel SuperRam TPI intakes. It would keep it shorter for fitment in cars with low hoods, but the runners would be long enough to not destroy all the low and mid range torque. Holley came out with that twin throttle body cross flow twin plenum intake, but having to use two throttle bodies makes installation difficult. There's a reason that none of the twin TB intakes have ever taken off, even though in tests I've seen, Edelbrock's cross flow LS3 intake outperformed the stock LS3, a difficult feat.

Was thinking more along the lines of a "send cut send" option. Send the files to a large 3d printing manufacturer of some sort.
