They are designed for motors that run higher RPMs (usually 3500-10000).

They are not that great for street driving.

Dual quads is very cool but usually you need a motor that is at least mildly built and the linkage will need some work or you'll have to look around for a kit. What size motor do you have?

You could get a 2" carb spacer (cheapest way) or raise the motor some (would take a some work). You could also add a blower to the motor and it'll lift it that way.

a blower is kind of the same as a super charger. just crams more air than a super charger or turbo. turbo is another option?
there 2x4 intake made for the 1500~6000 rpm range

Could you define "hi-riser" ? What you (or the seller) is calling a hi-riser may not be what we're thinking is a hi-riser. There's always a gray area.

I have been looking at intakes on ebay for awhile now and I have seen intakes advertised as High Rise and they may very well be, but it seems they are simply another version of a Air Gap intake.

The main thing that's been holding me up is how much money I have to spend and were the intakes are coming from. What I've found is for a SB Mopar made in the USA will cost you $200 and up. The ones advertised as new for around $129 - $149 are made in China. Another thing is that Weiand intakes while priced around $189 and up are also made in China, however my understanding is that this was not always the case.

I don't mean to high jack the thread and turn it into "USA vs China" but I feel knowing where the intake is made is an important part of making the purchase. Personally I will feel pretty weird strapping on a China made intake to my Classic '72 Dodge 340.
That in mind, I have China made Sunpro gauges all over my dash......

on the intake where you put the carb, it sits higher then a normal intake would.

If you need the riser or "lift" for your "blower scoop" a buddy of mine came up with an idea a while back to make a spacer for the scoop on his boat. The key part was that it had to look good and shine.

So, he and I drove to the Goodwill Thrift store, went to the pots and pans section and started looking for a polished stainless steel pot or pan that was a certain diameter for the spacer. I think that it took two stores to find what we were looking for.

Finally found it, bought it for about $3.00, took it home and cut the pan down to the needed dimension. It still had the rolled edge at the top and it looked bitchin'!

It shines, looks like a custom piece and you would never think that it once was a cooking pan!

I would love to see a pic of this!! And im not saying this cuz i think that it might look all white trashy like, im saying it cuz my grandfather does stuff like this and i think the final product is amazing sometimes.

You're better off. If you don't know exactly what your cam profiles/bore/compression ratio are, then you don't want to swap to a different intake and/or carb. If all of those components aren't matched, it will never run right.
I forgot to mention exhaust manifolds as well. All of these things basically have to be able to move the same amount of gasses to function properly together.

Instead of hi-rise or not, the question should be single plane (strip) or dual plane (street). If you have a dual plane try adding a carb spacer and see if the engine likes it, if it does maybe a single plane will be the route to go. If you already have a single plane then changing that in it's self will make very little difference.

Polarman is right, you have to have a balanced package. All that changing parts randomly will do is cost you a bunch of money and be very frusterating. Find out exactly what you have now and then determine the weak points and upgrade them. I know this from bitter experince, I've thousands of dollars in useless and unused parts sitting in my shop.

That's interesting, do you have a dual plane aluminum intake for a 340 sitting around?
