Anyone switch there fuel injection to a carburator?? If so can you post some pics?? I've got a pretty unique piece I'll post some pics over this weekend.

Nope, it's blasphemy!
Why do you want to? And the easiest way to do it would be get a GEN I motor, otherwise you have to keep the opti and computer for ignition.
Lots of guys have regretted doing this. The computer system really is cheap and easy to play with an amazingly flexible IF you are willing to learn and give it a chance.

Why the hell not? I if you know how to use a carb then its not a problem
FYI the fastest bolton LT1 runs a carb, but apperantly its record doesnt count for the bolton record since its a carb. So its the fasted, bolton carbed LT1

Comments like mine are necessary because a LO of newbs think the computer is a complete roadblock. At the local track most of the old school carbed guys are amazed at the power/drivability/economy I get out of my car, not amazed enough to retrofit injection to their cars but still impressed.

It is a roadblock in my case.My combo should make power upto 8k but I can only rev to 7k and the stock computer craps out
I have to make a decision on a aftermarket fuel management system or go carb and kill the computer stuff

That is fine, there are going to be cases where it makes sense for one reason or another. Just I have seen way too many guys with MUCH closer to stock cars think a carb was the answer when all it would have been was a different set of troubles. Most guys who are comfortable with carburators write off the stock injection much too soon.

That is quite the roadblock, and this might be the only reason I would go carbed. As 96 said, the PCM is pretty relyable and can be played with just as much as a carb. Many around can tune LT1s/LS1s great these days, but if you know a carb well enough to try it I dont see why not.
But I wouldent be throwing it out until I run out of RPM as described above.

rpm really is the only limit of the rpm performance wise. all other hassles like injectors there are adapters for, MAFs there are lots of options. Boost is a hassle to tune on the single BAR setup but it is doable.
i have a lt1 with 32 valve heads its a very rare piece the motor is about 85% finished No worries about removing the opti spark ignition there's all kinds of aftermarket block off pieces out there. As for ignition i have a msd distributor and a digital box. I mainly wanted to know what intakes were being used. My intake already has fuel injector bungs welded on to it. Since I'm eventually going to go with a turbo charged lt1 I will be using Big Stuff 3 to control the whole package.

Reason: grammar
Yeah sounds more like an LT5 in which case I would think sheetmetal is about your only other intake option. If it is an LT1 with 32valve heads then they must be Arao Dominion 32 valve heads and again talking sheetmetal intake. Don't know if anyone ever got a car down the track with those but a few guys have tried to build cars around them.
I think he probably bought one of those rare set of 32V LTx heads.
Anyways, the 8K rpm reason isn't exactly a good reason to go carbed. You COULD use an aftermarket computer system.
There's a reason we went away from carbs, greater performance and much better fuel economy. Now yes, you can get a carbed LT1 to perform much better than a LT1, but as soon as you tune that LT1 you're going to be ahead of the carb.
Cost to convert vs cost to get a tune, getting a tune and being ahead is a much better choice!
It has been proven that if it is a race car and streetabilty is not a concern carbs still make more power in all the tests I've seen. Hot rob did a 6.0L put a carb on the fuel injected single plain and gained 15hp or so. There are other test that I've seen the same results. The old carbs did not meter fuel the way some of the new "modified" carbs do. That is why prosystems and other carb companies are able to get a bigger carb to run better then the old ones. Some of the carb companies have some good write ups on different test that have been proven. Not all myths are true when it comes to cars.
But if it is a street car that see's a little track time fuel injection is the way to go. It is so easy to change a couple numbers on the laptop and changing jets suck but at the same time my car when carbed. 8000+ rpm's here I come.
carburated lt1 ???
