Cheap and unless you have direct injection, peak horsepower isn't that different.

The newer carburetors made these days are pretty amazing, gone are the days of shitty unreliable carbs that required experienced mechanics to adjust properly.

easiest way to swap an engine into a car without having to make a new wiring harness. It's quick, bolt on, you don't have to run wires or mess with aftermarket ECUs. You just bolt on a manifold and carb and put power to the starter and distributor.

too stupid/poor to run efi

If the engine was designed to run off a carburetor, why mess with things too much? Just furnish what the rest of the engine is expecting to see. It's the safest and most conservative thing to do. That's generally the market for carbs these days - people restoring old cars.

I personally would install a throttle body injection system if for no other reason than most people will wire in an O2 sensor anyway, even if they're using a carb and if you're going to go to that much trouble, putting a throttle body EFI system in isn't much more work and those things pretty much tune themselves.

I think I'd draw the line at converting over to multiport, too many things to go wrong there.
>>
>>17541124
If we're talking about "enthusiast" toys, it's probably because carbs are beautiful. Electronic injection systems are ugly solution, it's like building toaster over x86 cpu just because you want your toast to be toasted a little bit more evenly.

Simplest, mechanical solutions for the problems are amazing. It's like difference between having a digital battery casio clock and hand-made technological masterpiece with gorillion of little gears. No one gets excited over a fact that microcontroller can calculate right amount of fuel to be injected, but system that sucks in fuel using simple fact that there is a pressure generated by engine itself is just perfectly tailored for the problem. Computer-controlled fuel injection is pretty much brute-force.

Currently on a long motorcycle trip with a carbed motorcycle. In nearly a year of riding I've had exactly zero trouble. Works find with no adjustment between sea level and 5000m (besides throttle hold-open to set the idle). I could adjust it better for elevation with an external idle screw but works well enough without.

I'm sure I'd save a little gas with fuel injection, but if the fuel injection ever failed on me I'd be shit out of luck.

Because it's easier a lot of the time. Luckily my shitty gm 350s tpi works but if it didn't I'd just carb swap that shit and never look back.

Older efi like on a 350 in a camaro/vette is also really shitty for tuning becuz old electrics. Gotta buy a bunch of shit to plug chips into and program if you want to do any of it yourself. Tpi is better for cornering and shit like rock crawling because you don't want bowl float THEORETICALLY, but that's really sorta boomer bench racing and modern carbs are really good.

You have any certain EFI systems in mind? I'd like a suggestion. I'm thinking of saving for an MSD Atomic EFI. It's more expensive than most but then I could get the ignition to match and everything.
>>
>>17543090
I keep eyeing the FiTech 600hp system, and their fuel command center. Holley has a similar priced TBI unit which I trust more, but the fuel command center is a must. You basically run your standard mechanical fuel pump to this remote reservoir, and it pressurizes the fuel going into the TBI unit. This basically cuts out all the PITA you might have running a return line or modifying the rest of your fueling system.

The noise and feel, helps the car look period correct.

It also means the car is less likely bumped up into the modern car class at a track day.
>>
>>17543061
Some carbie cars have distributors.
>>
>>17543130
My entire problem is that EFI is uncharted territory for me and everyone else in my family, so if I have no clue what to do no one else will. It's a lot to drop on a part, but it probably will be worth it in the end.
>>
>>17543162
I highly recommend reading some HRM write ups. I have been reading like crazy on it. The FiTech Command center is basically the final part to having plug and play self learning EFI. Getting fuel to the old systems was always the weak link.

it will make a huge difference on your 460, aren't you running a 390CFM carb on it?
>>
If you have say a ford escort with a 2 liter engine.

If it's running carburetors you are guaranteed to race it in classic class.

If it's running an efi it's more likely to be bumped up to modern class where it will be less competitive .
>>
>>17543174
My current carb is an Edelbrock 1406, so it's 600 CFM. I think the accelerator pump is fucking up in it though, in idle if you bump the accelerator it hesitates then takes off but in gear if you floor it it starts to die. When going down the highway if you floor the pedal it doesn't hesitate at all

A carb will make just as much power as fuel injection, if not more, and they do it at a much cheaper price with a far simpler installation.

It is what it is. Deal with it.

if you're sitting there with pic related and want to get it running a carb would be cheaper, about $5-600 and you can have a brand new edelbrock intake and holly carb, that or go to a pick n pull and get used for almost nothing
>>
>>17543657
Some carbs (like those split Dominators pictured) have the ability to flow more air than even the best FI setups. So yes, they can make more power.
>>
>>17544642
not true in the slightest. carbs in those applications will flw more because they are what developed the most. no one is going to develop a manifold and EFI system to gain 0.5% when something on the market already does 99.5% of what it could do.
think about it. a well designed manifold has to flow more air because there are no obstructions from venturis and other parts of the carbs. the manifold will have more airflow that is also smoother.
The best flow would come from ITBs with a slide throttle or C throttle.
I won't argue that carbs are the best for engines like american v8s where there is heaps of untapped power and mods are cheap. it allows a cheap way of tuning for extra airflow but saying carbs will make more power than EFI Is just blatantly wrong.

otherwise you would see carb conversions popping up for every engine ever touched by tuners. but you don't. you see ITB setups

>>
>>17543657
yes inaccurate fuel metering
and having to manually adjust to changing atmospheric conditions
high level crabs can be just as complex as more simple efi
only problem I do have with efi is that with things like multipoint and direct injection
it's getting to the point where they are so complex and specialized that only the authorised dealerships can keep them running
sure you can get a little more power but it comes at the cost of every other aspect
and comes to rely on an increasingly narrow set of conditions under which it will work
.eg min max cherry picking
J-just h-have to let it warm up

It's cheap

There is no other reason, regarding tunes and reliability/simplicity EFI is the way to go, most who don't agree don't know how to tune their own car and these days we have much better ECU tuning capabilities than I when I used to tune my own Mustang years ago.

I started tuning like 8 years ago and tuning your own car required chips and maybe even swapping out the ECU, these days we have much better computers and tuning on the fly is a simpler process..

Either way I do like running carbs as well but its mostly for nostalgia, anyone who still runs one we would never agree about it since there is truly one reason to run a carburetor

You're broke as fuck

Lol. Go to places where people *actually* race, namely your nearest drag strip. Other than LS series engines, you won't find fuel injection anywhere. And even with LS's, some people *STILL* carb them!

When 0.10 second can mean the difference between 12th place and winning, those guys are looking for any advantage they possibly can. If FI could get them that extra tenth, damned right they would do it.
>>
>>17541765
What are you even talking about? You realize that carbs don't adjust for temperature or altitude right? And that even when properly adjusted they need multiple jets because they don't actually track very well.

https://en.m.wikipedia.org/wiki/Carburetor
>The main disadvantage of basing a carburetor's operation onBernoulli's Principleis that, being a fluid dynamic device, the pressure reduction in a Venturi tends to be proportional to the square of the intake air speed. The fuel jets are much smaller and limited mainly by viscosity, so that the fuel flow tends to be proportional to the pressure difference. So jets sized for full power tend to starve the engine at lower speed and part throttle.
>>
>>17547825
No boomers and rednecks at the drag strip are stuck in they're ways and can't into operating a computer so learning how to properly tune they're engines using software instead of how daddy taught them with screwdrivers is too hard.

Again it is purely for cheapness and ease of tuning. EFI will flow more and if you can't see that then you can't into physics and are retarded

You could have just said you know you're right, the laws of physics still apply to ma VEEATE and a well designed EFI with ITBS will flow better but I like my carbs, their simplicity and tuneability.

>import

Who get their shit pushed in by turd gens and fox bodies at half the cost.

The reason those 4 bangers run EFI is that's what they came with, and the aftermarket isn't there to support carb'd intakes. Besides, know how I know that import guys don't know a single fucking thing about how to make power? Not a single one ever does any head work. All the power comes from your head, not fucking bolt-ons. Bolt-on engine parts are shit.

A motor is an air pump, if it can't breathe, it won't make power. And if the heads can't breath the very most they can, then all the bolt-on bullshit in the world is for naught. It's just that basic. But import fuckers won't even do a simple port match with their intakes, let alone actually cleaning up the runners in the heads or making the chamber flow better. They're that fucking retarded.

Just stop already.

The only reason every new car is FI is because of government mandates via the EPA and CARB.
