If you are old school expert carb. mechanic, go carb. If don't know a thing about carb, do yourself a favor, GO EFI !! Simple !!
Very good video for someone who is considering fitting EFI. All the pros and cons considered. Many of which I hadn't thought of. Very well balanced video 👍👍👍
Carbs= fuel first, then air. Injection meters fuel by airflow. A drag car needs fuel first but doesn't turn corners so carbs work for that application. A rock bouncer on the other hand, will benefit from injection, it will stay consistent at any angle of g force influence.
You had me giggling at controlled leak..

After watching so many videos of people having problems with EFI I decided im going to stick with my carburetor set up. I haven’t had any issues with my Edelbrock AVS2 yet and its been turning on and running even in cold temperatures below 40F. I don’t have to worry about my ECU going out or O2 sensor going out on me.
I did a swap to the FAST EFI on a 82 CJ5 JEEP, I live in CO. it would start up bump of a key at -10 below no problem 4X4 on jeep roads at two miles high. The point is that I had a lot of problems with the EFI, leaving me stranded from fuel pump relay or O2 sensor and ect. The carb would run like shit at two miles high but it never left me stranded. And it was about 3500 for the EFI. I should have put the $ in a paint job 😆😆MPG the carb got 18mi the EFI 14 mi
@@christophershea2952 exactly! With a EFI you’re pretty screwed if it breaks down. I just recently installed a wideband gauge and a pressure regulator with a pressure gauge and now my carburetor on my K5 runs so much better now. The wideband gauge is a must if you want to dial in your carburetor correctly.
@@christophershea2952 they actually have a 4x4 off road carburetor from edelbrock.
Carburators have never caused me trouble in any temperature or weather conditions, and I've always lived in -40 - 100F conditions with 71 models onward. As long as they are periodically cleaned and adjusted every 5-10 years or so. And I'm talking cars and motorcycles. And I always passed emissions tests with 0% of anything bad. EFI may have some extreme conditions where it may beat a carb by a few percent in some performance parameters, but the amount of mining, industry, and production for all the added parts EFI requires creates a lot more damage to the air+environment than carbs ever did, IMHO. Electronics are a scheme to profit more as I see it. It's a development in profiteering, not really a development in environmental conservation or engine performance. If airplane engines run fine with carbs from -60 - 120F, from 500ft below sea level to 25,000ft above, there's no reason cars+motorcycles can't. And that not even including all the extra labor+materials+expenses involved in the computers that are required to read and manipulate the onboard computers. Nor is it including the fact that EFI does not monitor all appropriate changes in atmospheric conditions. Generally, they monitor air mass flow and an exhaust sensor which is not enough for the variety of driving conditions.
That’s why I’m very happy with my carbureted Volvo.
Thank you for this video. It's very helpful. I especially appreciate you covering the disadvantages as well. I have a 302 Windsor in a project car, currently with a 600 cfm Holley on an Edelbrock manifold. The carb is definitely not correctly tuned now, with poor driveability. I'm weighing the cost/advantages of retrofit EFI.
One thing I'd like to know is whether an aftermarket 4-barrel EFI provides any added hood clearance over an equivalent carb? Seems like it might not need to be as tall without the stack up of concentric venturis, choke plate, etc.
I have a 289 on a 68 and just swapped my 600 Holley for a sniper they are pretty much the same height the sniper maybe slightly shorter but not by much
The thing about fuel injection is that it won't leave u on the side of the road but a carb will
Thats not exactly true...alot of people just buy a classic car because they think itll make them cool. Must of those people cant install a battery
its not worth the swap if you go with holley sniper, im having EMI RF issues and have found countless you tube videos with many other sniper issues like t9uchy throttle, wire connector plug on injectors coming off, plus countless ECU failures
Luckily the 2nd hand Honda civic I bought was carburetor type.
F.I.is definitely better but parts companies are out for one thing like everyone else,money!they make it sound so easy and much better which both are fairly true but we don’t all have a couple thousand bucks to throw at our projects especially after they have been built for carb tech..carbs are expensive enough for me and the difference in power doesn’t warrant it but yes they are better.nice car and thumbs up on the tunnel ram,glad to see carbs on em.
My advice is avoid any throttle body with a built in ECU. Heat destroys ecus. I toasted two. Get a remote mounted ecu.
Well after dealing with carburetors, and now having fuel injection systems, I would never go back to carburetors no more bogging out the line! Are diaper locking‼️
EFI is ok, until it goes wrong. The price of sensors and fuel pump are a lot more expensive.
I have a 1991 Chevy K 1500 and I’m thinking about swapping it from being fuel injected to carburetor
Have you checked the MAP sensor readings? My map sensor in the Atomic died and caused similar problems.
Please go to Nicks Garage he has shown were fuel injection and Carburetors on dino and you can set and achieve more horsepower and torque with fuel injection☝️‼️
Skip everything and go Aces EFI. So easy.
im trying to do more research on carburetors… I have a chevy camaro 231 cu in 3.8l with a 2bbl carb. Are 4bbl better than 2bbl? Ive seen people put 4bbl carb on a 2bbl intake… is that damaging???
The 4 delivers more fuel and air therefore more power but it’s harder to tune and maintain
like you could not damage the engine with a carb that runs lean... you love to deal with clogged fuel residue in your carb every single freaking time you wana start the darn thing after sitting for some time. just go up a hill and you need to retune the darn carb. you then get off the hill, needs to tune again. carbs are nice and all, but they are just a pain in the ass. its a no brainer. EFI wins.
Worth the swap? No and Hell no.
My question is about the alcohol gelling with my carbs problem. I can take jelled gas and fuel injector and start and run. I'm tired of cleaning carbs. But, I'm a serious amateur, so what about fuel gel problems?
If your vehicle sits for extended periods of time or you live in a very humid climate, using non-ethanol (some call it off-road gas) or a fuel stabilizer designed for use with ethanol fuel when the fuel is fresh will go a long way from reducing modern fuel from going bad
A bottle of Lucas fuel system cleaner every few months or so can seriously reduce carb crud.
They realized carbs would outlive many people with less problems. Also a way to get higher MpG.😮
So they switched to fuel injection!!! MAYBE 🤔
Music off please! Cant hear anything! Terrible music
Nope
Your very negative towards the Fuel injection
In reality I enjoy FI on daily drivers. For ease of tuning/mods per bang for the buck carbs are still a great option
Exactly, reality encompasses negative as well as positive!
I got a 67 Ford Thunderbird 390 cc 6.4 l. I'm having all boats of trouble with the carburetor The car stalls on me I have to give it a bunch of gas when I start it. The carb has been rebuilt I've spent money at the shop looking over vacuum lines or different things. I'm not a car guy I don't wrench on cars am I better off going with an EFI conversion and just spending the money or taking this thing to the shop every time it has a problem with the carb. I don't want to wrench on the car but I want to own it and I want to make it work somewhere or other So what do I do in my situation I'm not going to work on my car cuz frankly I don't fucking want to I just want to drive it and enjoy it I don't think I have to do the work in the car too Have fun I bought it It's mine I can do with it as I want. I just want something that works I turn it on and it starts and goes.
Old cars is for old guys, new kids ride new car ! Simple ! If you don't know a thing about car, your playing the wrong game.
I stopped reading when you said im not a car guy and don’t wrench on cars. Yes EFI is amazing on new cars or cars that were equipped with EFI originally. However if you convert your car that originally had a carb to EFi you’re gonna have way more problems.
