Re: Carburetor for C5's? (GmasterB)
please no flames.. just an honest question. All it would take is an intake. I figure if someone is gonna go all out race with a vette.. than a carburetor with lets say a Vortech would be awesome.
Think of all of the electronics that would come off.. surely that would save a ton of weight.
Im not saying i would do it to mine.. but mustangs come fuel injected and they make carb intakes for those.. so why not an LS1??
Ultimately a fuel injected car is always gonna be faster than that of the same with a carb.. but you can go real fast for real cheap and keep it (you guessed it) real simple with a carburetor.
for those of you that think im nutz.. and im sure u do.. i'd almost bet that as LS1's get more dated.. companies like Edelbrock, and holley will come out with carb intakes. just my 2 cents

It's been done with LT1 and LT4's (C4's) but haven't seen it on a LS1/6. Actually, my 34 Ford Street Rod (Almost done) has a 93 Camaro LT1 which I removed the TPI and installed a manifold, distributor, and Carb. Runs great.

Re: Carburetor for C5's? (78Vette-SA)
actually you would make more power with a carb. Think of all the pro-applications that are carb... Topfuel, nascar (i think)... Friends of mine in the mustang circle, all run carbs, and they puck up at least 25 RWHP from the FI

The only advantage to a carb is simplicity. But forget about cold start ups in the winter, idleing with a big cam, etc.
I'm sure someone will make a carb setup for the LS1 sometime real soon. For like hot rods or some type of racing series where you can only run a carb, but have to run a factory block of the same year as your cars chasis. Or something along those lines.

Re: Carburetor for C5's? (Wide Open Throttle)
A lot of engine that came with EFI can be converted to carb, because the heads were designed for a carb motor in the first place. LS1 heads were never designed for that.

Re: Carburetor for C5's? (tito)
Actually, the right question is who makes an intake manifold for a C5 engine that takes a carb. If there was an intake manifold, any carb appropriate for a 350 cuin engine would work. Currently, no one makes an intake like that for a LS1 or LS6.
But---compared to electronic fuel injection, a carburetor is a lousy way to meter fuel. C5ers using their cars in race-only applications and having trouble with the stock engine controls, should get the GM Motorsports open-loop PCM that the ASA series guys use. I'm told it's non-OBD2 and user programmable.

Re: Carburetor for C5's? (66ImpalaLT1)
electronic fuel injection is not allowed in nascar or in the nhra pro classes. It's much easier to keep a level playing field in nascar with carbs. the carb teching process is done with a few simple measurements.efi would require a lot more work to keep people from streching the rules. as for the nhra,Warren Johnson said that he would love to see efi legalized in pro stock.he claims it would level the playing field because the cars would be much easier to tune eliminating the advantage that a few great carb tuners have. if you look at ihra pro mods,you will see that many nitrous cars run efi.it's much easier on parts and doesn't suffer from the mixture and altitude problems that carbs do......bottom line.......carbs are relics and best left to the classics.for any ultimate performance or ultimate driveability machine,efi is the only way to go.

Re: Carburetor for C5's? (tito)
you still need the computer for the ignition system unless you adapt a regular distributor to the engine. i did that when using a 2 litre cavalier engine in a race car that was converted to a carb. i just installed a distributor in the front timing gear cover and used the cam shaft to drive it. :chevy

Re: Carburetor for C5's? (clem zahrobsky)
Injection is definitely the way to go. Some of the "hot rod" type of magazines are even starting to get on this EFI kick. It is far superior to the carb. If have even contemplated converting my 67 over to EFI.
But if your heart was set on running a carb. I am sure a custom sheet metal intake could be made (Wilson Manifolds) http://www.wilsonmanifolds.com would make one if you wanted. You might have a little hood clearance problem…

Re: Carburetor for C5's? (Aaron's-coupe)
I remember reading in Hot Rod or a simular magazine about a carb intake manifold for the LS1. Go poke around www.LS1tech.com, someone there may be able to give you more info.
