Single Plane intake which elbow do I use?
I have pics on my digital camera, but not uploaded to my photobucket account. I Still have my modded LTX intake, just setting on my shelf in my shop.
I actually just started the car up today (haven't messed with it in 9 months) installed a new EFI connection setup, and having Race Proven Motorsports tune it via my Hptuners/LM1 wideband (no tuners where I live unfortunatly)

I agree dual plane would not the the right way to go BUT there are single planes rated for under 8500rpms which seems to be what you guys like to choose. Same problem folks have with cams "more is better".
Just uploaded some pics, figured Id post up my Supervic setup thats on my Procharged 383. Don't have to spend a lot of money to go this route if you do stuff yourself (been there done that as well) I bought some some stainless steel 30 degree washers and that fixed my bolt angle problem and it looks very clean ( I believe I cut thta angle done some, been over a year since I have did all of this.
This is a super vic for a vortec engine (slightly taller than a SBC super vic) and between my elbow, 5.63inch super vic, and a 3/8 spacer it fits my stock Ws6 hood (LS1 front end conversion).
Looks killer and I have less than $400 in the whole thing

Cam determines sign off RPM, not the heads or intake. My car made 430 ft lbs of tq, made 400 at 3000 rpm. And yes I will admit my combination is "off", it needs a little more cam to really move. But I like its street manners.
The Z06 MAF will support damn near any N/A setup that can be put behind it.
My car needs the tune touched up, no time for it right now. With the new converter it has traction issues, it has never been scaled I just been throwing darts.
IMO the single plane is a good mod, just have it worked if you gonna run alot of cylinder pressure, end cylinders will be lean.

how would i go about getting around the carb hat, intake piping and mass air? i just bought a set of dart 230's from lt1powr and im trying to figure everything out. also where do you guys get the intakes without water necks and distributor holes?
You don't get them like that, they have to be converted over and machined.
Offenhauser makes a single plane, dual four barrel manifold. The runners all sit level so it wouldn't be hard to machine them for injectors. Shouldn't be that bad to build a box type plenum with a removeable top to bolt down to the carb pads. Same similar concept as Weiand taking there Hi-Ram tunnel ram and making the Stealth Ram....it just wouldn't be nearly as tall.
Also I was thinking....instead of blocking off the distributor hole in the back of converted intakes, why doesn't everyone just run a distributor to drive the oil pump and just not have it hooked up at all? Seems like there has been alot of lt1 oil drive gear problems, and something like the vortec distributor would fit back there. I know that several companies also make drop in distributor "plugs" or whatever they call them for people going to a front, belt drive distributor, but wouldn't what I mentioned work and be pretty much free? Noone would even see it back up under that windshield. lol
Okay, this is going to be maybe a crazy idea, and I'm not sure if any of you are old enough to even know the intake I am speaking of....but here goes:

I'm not old at all, but I started off at 13 with my great uncle (he's 96 now!) and an '66 studebaker with a 230ci chevy motor. We did a single 4bbl offy intake, a 214º cam and a set of headers. It was a fun little car, even if I couldn't drive it at the time. I'm guessing this is the offy dual quad intake you're referring to?

I have a friend who used to run one on a solid roller 468 with just a pair of 1850 holley 600's on it.....but it was plumbed for a fogger and had a plate under each carb. He never took the car to the track, but I witnessed him take money from alot of people. Some cars were even trailered (supposedly 9 sec cars) in to the street racing spot and got embarrased. His car (68 SS camaro) was not modded that far from stock and looked and even sounded like a healthy resto than an all out drag car. It didn't even have a cowl hood....just the factory SS one with the little chrome bulges. The only visual clues were wheels/tires, a sumped stock tank, and full 3" exhaust routed like stock. I'm sure alot of his wins were due to great traction. He found that a 3.55:1 gear worked best in it with the street tires he ran. I think they were M&H, but it's been about ten years. I know they were not the old M/T dot bias plies that they had before the ET streets. I'm sure his car would have ripped on a set of what's available now.
