IIRC, Teal did for a turbo setup or something. Or perhaps that was a header.
Anyways, cash is tight. Well, actually, it's not. It's just I can't seem to ever spend any real money on doing things the right way. Hence I tend to use the el-cheaponator route at DIY things that one really shouldn't. So, if this thread gets too freaky for you just hit the back button.
This is what I should be buying if I wasn't cheap:

It isn't as pictured, it's actually built a little better and seems to have equal length runners and a dual pane setup. Or perhaps that's a different model. I almost picked one up used for a steal but some YJ guy with the big bucks swooped in and out-bid me. Well, 'swooped' doesn't exactly describe it, but you get the picture.
Now, you're probably wondering why I want a 4bbl intake? Well, it's to run propane. An Impco 425 for the record. Which is stupid. But a totally different story.
But enough of the irrelevent back sotry. Has anybody done anything this silly and seen reasonable results? I'm not expecting any real screamer on the performance here... If it WORKS I'd be happy enough.
My plan WAS to use 2x1.5x.188 HSS (or something like that, the ID matched the ports on the head) but my local steel yard doesn't seem to have it. And I'd rather not buy 20' at the price they want. Then I'd simply copy the stock intake design for the most part other than it would be eniterly HSS, odd geometry, and have the 4bbl carb pattern on it. The corners wouldn't be so nice, as I can't bend that stuff. But that's the price you've got to pay. If you look at the stock peice it's not like they did a great job of smoothing the corners (given my early renix eample).
So, abondoning that for the moment, I've decided to look into pipe/round tube. Which leads to a nasty problem in that it'll never match the rectangular ports on the intake. I thought about hogging out the ports a bit, to try to make them more or less round. But I'm pretty sure the casting isn't thick enough to do that in any sort of nice manner. So, given that this thing isn't going to work beatifully anyways, should I just try to match the ID size to being somewhere around the vertical size of the port? And just not worry about the poor flow characteristics that are inherent of doing this (I mean, it's gonna suck anyways!)? The advantage to round is that I can bend it with minimal deformation, which means that I can actually put fairly nice corners in it to a certain extent. And yeah, you can get those pre-fabbed tight radius 90*s too.
The other option is to take some HSS of the appropriate size on the horizontal dimension (1.5", 3/16 wall) and incorrect size on the other dimension (3") and make an angular cut along the top side of it, then weld a peice of FB over it to make a tube with a neck down. This would be alright, depending how well I can cut the angle in my chop saw. That and I wanted to minimize welds if possible as I know the inside of them isn't going to be perfect. But I am somewhat convinced it is my best option given that I don't really have many good ones.
So, thoughts? Feel free to call me an idiot. I'm well aware of my mental condition.
