You don't have to dump fuel. All I have to do is turn off the pump and let the bowls empty, you can hold a container under the bowl. Also if you go to change injectors you are gonna make a mess as well.

I am surprised you are able to run the 28lb injectors. That is what I had in my camaro with stock heads and a smaller cam and they were running right at 100% duty cycle.

Yes, but it really isn't that difficult and once you get it where you want it your good to go short some minor tweaks here and there.

Everyone knows what FI can do. It is on the wife's minivan. Gives her a boner everytime she cranks it over just thinking how much more high tech it is than a carb.

For some people they're going to stick with what they're familiar with. Take my dad for instance. He's an old school guy, calls me lazy since all I have to do to tune my car is turn on my laptop, few keystrokes, and voila. The car is tuned. I know that's an exaggeration but you get the point.. ![Happy](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_stretch.gif)
I chose to go the EFI route cause that's what I know how to tune. Not to knock the carb guys but you stick on of those infront of me and you might as well be speaking Chinese. I came into the car game very late. I'm a computer guy. Before I found out you could tune a car with a laptop ZERO interest in cars. None, zip, nada. When I started playing around with my 94 Formula that opened alot of doors and I started soaking it in like a sponge and it still hasn't stopped to this day. Then the LSx came along and holy crap, I'm having fun...![Happy](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_stretch.gif)
Point being is, like I said earlier, most people are going to stick with what they're familiar or comfortable with. Carb, EFI, or little hamsters running under the hood. Every now and then you'll get someone who wanders out of they're comfort zone into unfamiliar territory, least to them. It's doesn't matter if it's carb or EFI. They all still run the same. It's jsut a matter of how much work you wanna do..![Happy](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_stretch.gif)

Now you are exaggerating. My laptop was free, but you can get one at the pawn shop for $100. My efi live software was 300 bucks from a fellow board member. Total out the cost of the carb intake, the msd box. Its more than tuning software. Intake and box is what 600? Then the price of a good carb, 400 bucks? So $1000 for that setup, you can spend way less on stock efi stuff.

Putting a carb on an LSx motor is like taking a work of art and wiping your *** with it.
Car companies stopped using carbs for a reason... fuel injection is better! It meters fuel much more accurately and therefore is capable of better efficiency and more power.
If you don't care about those factors, sure it's simpler to use a carb. But I'm gonna have to agree with Cam72aro and say... Why go through the trouble of swapping in an LSx and not finish it right?
If you want power on a tight budget, a GEN1 SBC, or and BBC can handle that job. If you want modern technology; power, and efficiency, then an injected LSx is a great way to go.
Just my 2¢

I'm so tired of messing with carbs (I'm not a good carb tuner, combined with msd ignition gremlins)
decided to do the LSx swap
I like the look of the carb, but want efi
think I'll go in the middle w/ vic jr intake and efi in the future (using ls6 for now)
good thread

also people like to play to their strengths if people like tuning software they will probably go injected, if people like tuning carbs they might go that route, its their cars

whats so wrong with having a 3rd gen SBC with a carb?
you guy are hilarious though, you guys take so much offense to sticking a carb on a LSX motor, just as much offense as the RX7 guys give me for putting a SBC into their beloved RX7 haha
like i said different strokes for different folks

One thing you guys are not considering is the fact that with the msd 6010 box you dial in your timing much more precise to clean things up. With a sbc or bbc you can't do that. If we want to run a map sensor we can tune part throttle also. Throw in a wideband and a good carb and it will be just as efficient as an efi car.

The sensors are very reliable in LSx motors. In my car's 215,000 miles, the only sensor that has been replaced was the MAF sensor, and that was only because I was a moron and overoiled a K&N.
In fact, in 215,000 miles, I have had zero fuel injection related issues. I replaced the injectors at 201,500, but only to supply more fuel for my new motor. Except the injectors, all of my electronics and fuel system was reused on my new longblock.
I've owned three carbed SBCs and they were all a PITA. A wideband certainly help tune a carb setup, but it doesn't eliminate the hassle. Depending on the carb, it'll probably require frequent adjustments, much more frequent than I care to deal with. With EFI; once you set your tune for your setup, and get it right, you never need to touch it again.
I love plugging my car in to see what's wrong with it (which almost always leads to an immediate conclusion). I also love the 32+ mpg I get on the highway.
At some point, you just have to admit that you're hanging on to old, obsolete ways, and are unwilling to move forward, no matter what the advantages.
I don't mean to **** anyone off, but you want opinions, so here ya go.

I'd love to see that. If that were true, every car on the road would have a carb. Because if that were true, carbs would also have no issues meeting emissions requirements.
