Has anyone ever done this? Or know/seen anyone who has done this? I had this idea a few nights ago and i want to put it down and paper and see if i really want to do it.

I have somewhat of a list of things i will need but also have a few questions. Such as, will it fit under a stock 95 hood? What happens with the computer? If i leave it will the opti be able to function for timing? Will running no computer at all keep anything from working/running?

Also, does anyone know of where i can find a list of parts to make the conversion? Does anyone sell this as a kit? I have searched on the boards and found no thread on this. I have also searched the web all last night and today.

Thanks ahead of time for the help

 

Might wanna search again. I awnsered this exact question yesterday

It's not worth it IMHO for a street car. Too much work and sacraficing too many things (like cowl and wipers).
My wifes car is a carbed 4th gen lt-1, but it is in a 3rd gen car so we have no clearance problems. You need the GMPP intake, a carb, a way to control your trans shifts, a FPR for the carb, plus about a million other little things.

Thanks, I'll try another search

 

If you are interested I have the intake (GMPP), a fuel pressure regulator (Mallory) and some other items you could use if you want to go carb. I had this setup on my LT1 for a short time before going back to FI. I may also have a Holley street avenger 770 carb and distributor and new MSD wires if you are interested. I also have a few extras that I could throw in as well, shoot me an email if you are interested. Basically what I have is a complete kit minus intake gaskets and fuel line.

 

Actually, it is worth it and NO, you don't need "a million other things". I've answered this question quite a few times. I've done this a few times and it's very simple. You don't have to get rid of your wipers or the cowl but it makes it easier. I carbed an LT1 before I went with the traditional small block chevy. All you need is the intake, carb, distributer and spark plug wires, coil, fuel pressure regulator, and misc. fuel lines and fittings. You can completely get rid of the computer except for 2 wires. The large purple wire and small black ground wire. The black is a ground (of coarse) and the purple is the ignition wire that goes from your starter to your ignition key. As far as running a 4L60 tranny, and since it's electronically controlled, I wouldn't think it would work but you can always go my route with a th-350. You can take the opti off and get it out of your way, you can still retain your heater, power windows, door locks, keyless entry, lights turn signals, all of it. None of it is controlled by the computer. Very easy swap and worth it if you ask me, very easy to tune and work on. Just my $.02 Good luck!

 

I would never go from EFI to carb but thats just me 17mpg city 25 Mpg hwy with 400+RWHP and 400+RWTQ and the ability to tune across the board timing and fuel is just to nice IMHO. With that said other then some of the isues related to the F-body wipers ect.. if you have the 4L60 you can get a $70 lock up kit for the TC and will be fine for you 97 aplication they make a trany control box for the 4L60E but it is expensive. Good luck

 

rickyzZ28 - I'm researching right now, not looking to buy yet. But thanks.

carbed93Z - With a cowl hood for a '95 formula, everything will fit (STB?)? Also, i can go with a carb'd LT4 manifold and LT4 heads with everything else that you mentioned correct?

 

The EFI is more accurate and flexible than a carb could ever hope to be, and a 95 is very cheap to tune. I strongly suggest you look into what the EFI can do and is capable of before yanking it. Most of the people who ask about this do so out of ignorance and end up seeing it would be a mistake. Heck even the guy who offered to sell you the parts says he went back to the FI. Those advocating this what do you THINK you would gain?

 

Who said i would "gain" anything? I completley aware of the EFI system and what it can do. Its more of personal preferance. How many people you know with a carbed LT1 in a 4th gen anyways? I didn't ask for people to back up the EFI system (though your opinions are welcome). What i did ask for was people who have done it and what it takes to be done as far as parts and labor.

Thanks for the posts so far guys (including 96capricegr - in case he thinks i was bashing him, because i wasn't).

 

It can be done under a stock hood retaning wipers. I just did this at the end of last season. I am using a victor jr. intake with $70 in machine work to get it to fit the heads. Msd probillet dist, msd digital 6plus and using the stock coil for now. If it is an every day car i wouldn't do it as the gas mileage sucks, but it has a amazing cool factor when you pop the hood. It also clears up so much cluter that it is rediculous. I will give you a heads up that i didn't forsee happening. When you get rid of the stock wiring harness the plug that goes to the alt is not gone and the alt will not charge. I belive the way to get the proper signal is to run a wire from one of the body connectors inside the car that goes to the volt guage. There is a resistor in there the drops the voltage as to note cook the alt. I cooked one alt by running batter voltage to that connector.

 

Nice! Thanks alot. You wouldn't have any pictures would ya?

 

unfortunatly no i don't. If you have any questions feel free to shot me a PM
