was looking on ebay for random parts for my car and i came across a high rise intake manifold. does anyone know the pro's and cons of having one ?

and are 340 & 360 intake manifolds any different from a 318's ?

 

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

They are not that great for street driving.

 

oh, bummer, what about the intakes with two 4bb carbs ?

i'm looking at getting a blower scoop and i want it to stick out of the hood, is there any way to raise it with out a highrise intake ?

 

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.

 

have a 318, when i baught it i was told it has a cam bored and has race heads. but i have no idea if all of this is true tho.

by blower is that like the whole super charger deal or ?

 

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.

 

i agree, i wouldnt want an intake made in china on my car... i'm not sure where my after market guages are made, i'll have to look into that.

 

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.

 

I know a guy who has a blow "air cleaner". But he wants a pretty penny if hes going to sell

 

I tried to upload a picture of my buddy's thrift store spacer but, the picture is too big.

 

might just go for a hood scoop then =P
not looking to pay out the *** for somthing along those lines.

 

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.

 

Email it to me and I'll resize it and post it.

 

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?

Sorry no, but I do have one for a RB. All my stuff is for a big blocks, I just never could see the sense in small blocks. Just my opinion.
