last try, LT 4 owners
I have a LT 4 in my 64 GS Corvette and can not use the stock air cleaner setup. I had a post about disconnecting the MAF and it looks like that stays. I am looking for a setup that basically keeps the MAF and air cleaner close to the throttle body. Any ideas?

Wish I could be of more help here...but I'm just totally stabbing in the dark. Could you perhaps find some rubber tubing (I see the stuff all the time in turbo'd cars and those with lots of plumbing to achieve "ram air" - know the stuff I mean?) and cut it to a shorter length to go between the MAF and the TB? Also, use a similar piece on the front side of the MAF, and have a piece made/machined from aluminum to attach an off-the-shelf K&N filter to? I imagine it'd have to be one helluva filter...some piddly little cone wouldn't do the trick, as I think you'd collapse it at WOT.
...I dunno...just shooting "from the hip" here - perhaps some others will chime in.

I jus stuck a K&N filter on the end of the MAF sensor. S&P makes several other air cleaners that also fit onto the end of the MAF sensor.
Here iis the S&P web site http://www.hotrodlane.cc/
If you are looking to get less distance from the TB then the F-body elbow mentioned in other posts would be the best rout
Here is a pic of the set up I used on my 84

One, you can have someone reconfigure your 96 OBD2 PCM to run in speed density only mode, or two you use a F body PCM from a 94/95 model year and have it configured for speed density. The 96/97 OBD2 PCM maybe a bit tougher to setup in SD mode, I can't remember for sure but if it is then the earlier 94/95 OBD1 PCM maybe the better alternative. I can double check about the OBD2 PCM, as I am home now and I don't have my software here to check.

As it is right now I will be using something like FD2Blk has. I want to keep it as close to the throttle body as I can because I have a lot of air coming in from the large GS hoood scoop. I have a 95 OBD I computer but it set up for the LT 4. I like the idea of trying to get the rubber tubing from the supercharging or turbo companies, I did not think of that

Check out the S&P site I listed above. They have some filter assy's that stick out much less then mine did. I dont think you are going to be able to get the MAF sensor much closer without the use of an elbow because of the transition needed from the TB shape to the MAF shape.

gm high tech did a thing with blue thunder where they used a 4" to 3.5" (or whatever the maf is) exhaust reducer to install their nitrous nozzle.. it shoub be alittle shorter then the stock one.. OR.. i saw that the lt1 style firehawk intake bellow is plenty shorter than the corvette below.. i have been looking ofr intake ideas myself because i did a converted lt1 intake in a 91 z28.. and its speed density.. and my stock intake bellows would suck themselves in under full throttle. so i bought a vortec lt1 intake elbow and 99+ chevy pickup air filter to get me by.. i am goign to upgrade the filter to a bigger k&n but it would be something to get you going! email me for pics!! pr0zac623@aol.com

Perhaps I misunderstand what is required - the MAF to TB transitions
in size. The F-body (and possibly the B-body units) already mentioned
seem like they might do the trick.
Another idea is to have a transition fabricated from aluminum - a
competent sheet metal shop will have the necessary experience to
lay out and weld to your specifications.
If you need a source for silicon hose, Pegasus Racing is one to look at.
