You right ...meennn...you and me have same in common...carburator is very good with it comes to effeciency...or consumtion of fuel

I'm assuming you have the 302 cause the cop cars had the vv carb which was a total flop, I had an 83 with cfi and that thing was a pig (slow as hell just ate gas)

Yeahhhh i got a 87 box crown vic ltd with a 351w stock heads and aftermarket intake ported and polished myself cam stock with a POS variavle venturi carb and replaced with a basic 4bbl carb, that 40foot long car can get down and go and no computers or bird nest of wiring in it,

+Robert Floyd yep!

you bet your ass thats correct

Mark Kromer It was a flower car.

Hell yeah music to my ears

Uhhhh? Except 8 throttle bodies....

Thank you, TroyaE117!

Summit Racing which is best when comes to milage for bikes?

A dinesh to answer your question, efi will be more reliable, but Carburetors are easier to maintenance

@@thejohn6912 I'm building a truck to be an "overland" vehicle for long self sufficient travel. Would you suggest a carburetor, so that it can be serviced easier on the road?

Thanks John!

boldmoves6000 , Do you have to buy a specific EFI converter

HI Viron Vargas, Unfortunately, we do not have a kit that will work on such a small motor. Depending on your fabrication skills, you could build a kit yourself. We have computers that will work on 4 cylinder motors, just no complete conversion kits!

Unless you have throttle body injection. lol

You mean the fuel port injection

+Matthew samson, Your Hyundai Tiburon is fuel injected currently and when running properly will have better drivability and fuel economy than a carbureted car!

Hi rag Doll, We wanted to make sure you got our response on this video as well, in case other viewers have the same question. The choke wire will be on in the run position. Use the original coil 12 volt supply from the ignition switch, it will be live in run & crank positions! Good luck! Thank you for watching.

Hi lopezzcl54, We have some additional questions for you. Can you give our tech department a call? 1-330-630-0240. Thanks!

+michael salatte , While both a carb & EFI can be tuned when using forced induction, it really comes down to what you are comfortable with if you will be the tuner. Beware though should you decide to go with EFI, not all systems are capable of forced induction. Give us a call, we can help you pick the right system. 1-330-630-0240.

Hi Vintage Joker, It’s not possible to do both. Injection works with pressure and Carb’s work with vacuum. Injection systems fix many of the problems that come with carbs. It’s basically like having a carburetor that never goes out of tune. There’s a lot of options for you. Give us a call with your application and we’ll find the best package for you. 1-800-230-3030

Hi Joseph Francis Z. Teves, We really have no way of knowing if this would work for you! If you have read somewhere that it will and you believe it, proceed with caution. Good luck! We apologize we couldn't offer additional help.

Hi Rich M, This is where tuning experience comes into play. When there is no safeguard such as a knock sensor, you have to make sure that the ignition timing and fuel delivery are just right for your combination.

Avery752, We need some additional information from you. Can you give our tech line a call? 1-330-630-0240. Thanks!

WOW I didn't know camaros came with the 2.8. I thought the v6 was the 4.3.

The tbi system in those camaros were an awful design. You'll be doing yourself a favor in getting rid of the thing and have a carb, but the LO3 was a very restrictive engine to begin with. If u really want to keep the 305, put on better flowing heads, a better camshaft, and a intake manifold that'll match your heads, and that will bolt onto a 50mm modified tbi system, edelbrock sniper, or even better, a super ram efi! Carbs are awesome though, but a properly tuned efi would exceed a carb.... it's just 10x the price of a decent carb. I've seen 305 engine pump out 400hp, or up to 450hp with a 334 stroker kit, although you're better off buying a built 350, or a 383.

destruction12100, We are sorry to say that we do not currently offer a kit to service an engine that small. Good luck!

+bolando tero, Can you please call our tech line at 1-330-630-0240? We need some additional information from you. Thanks for watching.

+Brown Brians Jeep , Any of the systems you’ve mentioned are very good. I would not hesitate to use either of them!

Hi james1968ify, While it is best to have the correct intake manifold to begin with, there are adapter plates that will work in a pinch providing your hood clearance will allow for it!

What did you go with and how was the difference performance wise?

It's not a carb. It's a throttlebody with two injectors. The Carb will squirt a stream of gas, and the throttlebody injectors will have a spray or mist. The spray from the injectors will atomize much better and have a much cleaner and complete burn. I wouldn't do a carb conversion on a truck with a throttlebody.

Chan Raxter what fuel injection are you comparing to? Sequential multipoint direct injection like on most European. Will always give more power and tuneability than a carb ever could. Especially on a turbo or supercharged engine. They are timed to ignition timing and injected next to the spark plug in top of the head usually. This allows more fuel to be injected whilst getting a complete burn due to better atomisation of the fuel and better mixing with the air as the air can "swirl" with the fuel

I am comparing the same systems he was talking about in the video; something you can buy and bolt on your car, right?

Chan Raxter i see. so not what I'm on about then as its a bit more than just a bolt on. how many injectors you compare to? you can get 2 injectors before butterfly valve. fuel injection before the throttle body probably will give a slight improvement in some cars at altitude though

Hi Oso'. Can you please give our tech line a call? 1-330-630-0240. We need additional information from you. Thanks!

Hi P Money, Thank you for watching! Can you give our tech department a call? We have several questions, 1-330-630-0240.

***** I know it has fuel injection but they have different fuel injection kits and I just wanted a suggestion that's all

Im running Holley's Sniper EFI system in my 89 C1500. it works great. and you wont have to change anything else except the fuel pump and adapt the current fuel system to the new throttle body ( I simply got fuel injection hose long enough to run from the throttle body to the fuel filter ) and possibly a spread bore to square bore intake adapter.

casimirobuenabista , Yes, the potential is there depending on the kit you chose. Give us a call and we can help you pick out the correct one! 1-330-630-0240. Thanks!

Hi Christopher Ortega, Yes, you absolutely can swap it for a 4 barrel carburetor. Give us a call and we can help you pick out all the correct parts. Intake, Carb, linkages, gaskets, bolts, etc. 1-330-630-0240. Thanks for watching!

No. There’s a lot that goes into fuel economy and those old heads are terrible for economy. You need more throttle input to achieve any power. They add weight, their combustion chamber design isn’t designed to make the most of the combustion process. Those heads were designed to try to reduce emissions. If you want the best economy possible you need to reduce the overall weight of the engine and reduce the weight of the rotating mass. Good aluminum heads with modern combustion chambers, small roller cam with light weight (spring tension) valve springs, single roller timing chain,light weight rods and pistons, 9.0:1 minimum compression, MSD ignition with big wires and good old basic copper plugs, a good basic aluminum dual plane intake, a single snorkel air cleaner with a connection to a heat riser to take hot air from around the exhaust manifold and a 195 degree thermostat with electric fan. These things will help reduce fuel consumption.

Well they do alot more than just provide the fuel injection. Im running a Holley Sniper EFI system on my SBC. It controls timing with the proper distributor, it has a built in two-step, controls nitrous, and eventually boost. it ran me about $1200 with a Walbro 255LPH in tank fuel pump and i love it.

+Angel Colon, This is directly from the MSD Atomic FAQ page: What’s the smallest and largest CID that can be selected? The Atomic EFI will support engines with as at least 100ci to 800ci (maximum).

Hi *****, Thank you!

Summit Racing No Problem, you folks rock :D

None of my fuel injected cars start as fast in the winter as my carbureted ones. In fact if my injected cars don't crank very fast they will not start in Minnesota. My carbureted engines will start even if they crank slowly. The injected ones need some cranking time for the computer to set itself up to give the proper fuel mixture which wastes some battery power. I can pump my carbureted cars before I start to crank the motor which gives them an advantage in starting. Otherwise your statements are are accurate. (Mechanic for 44 years.)

If an emp goes off your dead in the water like marty on a hover board over the water

damn me too

+Eightbanger, Sure, reliability, easier starting hot & cold and better fuel economy. Depending on the system you choose, it may have a nicer look to it as well.

Summit Racing Thank you.

Hi Yahya, Ae you referring to Motorcraft? We would need exactly what you have. Thanks.

Sounds like its starved of fuel. Bet it soemthing to do with the carb or fuel supply

It could also be an issue with the secondaries. They may require adjustment. That bog occurs when it gets too much fuel and not enough air. The accelerator pump could also be at fault. A stock fuel pump should have no problem supplying that engine (I have a similar setup on my 85) but if the pump is going out that may be an issue.

Hi Peter Kapica, Honestly, this would be a step back in time! We have no parts or kits that would enable you to do this, sorry!

It is possible to custom fabricate a intake manifold with some pipe and 30 minutes of welding. Or a better idea: The ford pinto used a intake manifold and a carb, so maybe i can use a ford pinto manifold and modify it to fit the accord.

Peter Kapica in all honesty its a silly idea, your going back in time as summit racing said, plus your probably loosing power and the cost would be alot more than you expect... its better to opt with EFI because of the lower cost and the ability it has over a carb. usally these days v8 muscle cars that are dedicated to the theme have carbs, and old school cars that dont need to be modded at all. Good luck

When a solar flare or emp hits, I want a car that'll start

+Peter Kapica well that really is a pretty weird example but. i doubt that will ever happen, and you wont be in a situation to drive a car when everybody is running around because a solar flare destroyed everything

Hi El Compa Junior, Can you please give our tech line a call? 1-330-630-0240. We need some additional information from you. Thank you!

Typically fuel injection gets better gas mileage than a carburetor below is a list of the fuel injection kits we offer www.summitracing.com/search/part-type/fuel-injection-systems

Hi Chase Reed, Unfortunately no, the transmission must have a computer to shift it electronically. When you by pass the fuel injection on the motor; the computer will not be able to function properly. We offer stand alone transmission control computers; give us a call and we’ll help you pick one out. 1-330-630-0240.

Just convert it to manual.

Hi colby rodig, The newest available fuel injection systems are now self tuning (within reason) so that means that you wont have any jet changing to mess with and wont have a choke to deal with either. But it will still provide great performance!

Hi mate, people bag carbies and EFI alike, both have their upsides and down. Carbies are very affordable, the biggest problem people run into is running either too big or too small a carburettor for their application, or buying a used carburettor that has been modified to suit another vehicle. Either case will lead to disappointment. Both systems are reliable, but different. Carbies can give trouble in extreme cold or with large variances in altitude. EFI can stop a car with a dead battery where a simple push-start may have sufficed with a carburetted one. Either can be fixed with relatively simple tools - a laptop for the EFI and a few jets and a screwdriver for the carby. Like I said, they're just different. Most stock, out-of-the-box carburettors are quite good if sized correctly. Ask around and see who has fitted what. Lean to the smaller size if possible (eg 600cfm instead of 750). My daily driver (245ci 6cyl Chrysler Valiant) is topped with a Holley 465 Street Avenger and required almost no modification at all - I literally bolted it on and it idled, ran and drove quite well. Even got good economy; 20mpg @ 65mph on a non-overdrive 3spd transmission. Bang for the buck? Yes indeed! EFI is a great system and comes in several forms, most likely will be throttle-body systems for the average installer as of this date. Great things but they do require technology to tune, although many are now self-tuning to a certain extent. You still need to get them set up properly and know what you are doing to really dial them in to a specific configuration, but after that they're like a carby - set and forget. For my money I will still use carburetted engines as they are simple, cost-effective and easily fixed in the event of something going wrong. I generally do not travel with the equipment needed for sorting EFI, but do travel with a spare set of jets, powervalve and basic tools for the Holley in my vehicle. Both are unlikely to break down if looked after but that's the point - you want to be covered if they do! The best money to spend in any setup is an AFR gauge. Mine is from Innovate and was very simple to set up and calibrate, and was invaluable in calculating jet and valve changes to my vehicle. What I thought was a rich cruise was actually bang on stoich, and my slightly hesitant acceleration (I thought stumbling rich) was actually leaning out on kickdown. The gauge makes things easy and was $200 including sensor and computer. Best of both worlds, perhaps?

Hi *****, A 4150 has a metering block on both the front & rear of the carb with interchangeable jets. A 4160 has a metering block on the front but only has a thin metering plate inside the rear fuel bowl. If you need to change fuel delivery to the rear (4160), you’ll need to buy a new plate or a metering block conversion kit and jets! Let us know if you have any additional questions. Thanks for watching!

Cyril Willard Cable, Both work very well when chosen and tuned properly. Ultimately the decision is between you and your wallet!

I'm asking because i'm 11 but yeah your answer makes sense but which one is best for drag racing

Cyril Willard Cable Either one can get you to the same power but with different modifications to get there. But injectors can inject wayyyy more gas way quicker than any carburetor i'm aware of. But too much gas isn't good either...

Thanks for watching !

Hi Jody Hebert, Well, it really depends on the vehicle you are working with. There are systems on the market today such as the MSD Atomic that makes it as easy as it can be. Most all the necessary sensors are incorporated into the throttle body unit that gets bolted onto your original carbureted intake manifold. Take a look at this system, it’s a good one.www.summitracing.com/search/department/air-fuel-delivery/part-type/fuel-injection-systems/brand/msd-ignition/product-line/msd-atomic-ls-efi-fuel-injection-systems?N=4294951509%2B4294925975%2B400122&SortBy=Default&SortOrder=Default&autoview=SKU If you need more info, please give us a call on the tech hotline. 1-330-630-0240

Fuel injection is not safe from fuel gunking up, mater of fact injectors tend to stick open when old varnish gas gets ran through them and can cause injectors to hang open and flood or even hydro lock the engine, no fuel system is safe from old varnish gas or ethanol gas.

@@briang4470 I own two 87 f150's, one is a carb and the other is Efi. When I don't drive the Efi for a few weeks I never have issues with the truck starting and I think they're designed to go well over 50,000 to 100,000 miles without issues. On the other hand, my carb gets gunk within a month or few weeks of not starting it.

@@refugiorod if your carb gets full of trash and gunk in as little as a few weeks, then you have some other issue like contaminated fuel,dirty fuel lines or fuel tank, or the rubber lines are disintegrating. Carbureted vehicles especially with todays fuel will evaporate dry after a few days to a week so when you come back to them you should only have to crank for a few seconds to refill the carb and then it should crank right up with a pump or 2 of the peddle. I have worked on tons of carbureted vehicles over the years and if everything is clean and in good condition, you should have zero problems unless the vehicle sits for a few years with super stale gas. I have seen fuel injected vehicles have injectors stick wide open if ran with stale old nasty fuel so both systems do have problems but none of them are bad, carburetors get a bad name from people having other issues or not understanding how they work or how to fix them.

@@briang4470 Ethanol is the culprit here. Back then, regular gas never had issues with gunk. They're video's out there of old cars still turning on after many years of being parked, no problemo with the old gas, they still turn on. It's the ethano. Ethanol attracts moisture.

@@refugiorod That is absolutely NOT TRUE. Old gas would turn into this very thick and stick brown molasses like substance known as varnish. Trust me I have cleaned out hundreds of old motorcycle and car gas tanks that hadn't been drained in over 20-30 years, it's some super nasty stuff that will not run. Yes ethanol does attract moisture but that is not the reason for all your problems. There are still thousands of carbureted cars,trucks,motorcycles, and boats and 99% of them are still using ethanol fuel with no problems. Ethanol does cause issues if let sit for extended periods of time like 6 months or longer but so does ethanol free fuel. If you dont believe me go fill a gas can with 1 gallon of ethanol fuel and vent it and then go get another can and fill it with 1 gallon of ethanol free fuel and give them about 6 months to 1 year of sitting and see what happens. The ethanol jug will mostly evaporate but there will still be some varnish and stinky old fuel left that will not run and the ethanol free can will be mostly full but will have a very thick and nasty varnish in it that will not run.

Hi Abrar Ul Haque, It is a matter of preference. Both systems have benefits. Your best bet would be to research bikes similar to yours to see which system works better on that bike. Thank you for watching. Good luck!

bt shouldnt a fuel injector work better on every bike? if u put aside the fact dat it costs more.

Yes, Efi is always better for anything because you can more power while getting fuel economy

Except for FI.

LOL That depends on the size of the injectors.

Hi Eric Brown, Thank you for your input and thanks for watching!

no problem

Eric Brown

magnetstoo lol. The thing is they earn more money with efi. It's all about money!!! Carburetor wins!

+Antivorg , Ok, well, while both have butterflies to throttle air, both release their fuel into the air stream entering the motor differently. One delivers fuel that is held under high pressure and released by the computer at just the right time and the other allows fuel to be drawn into the low pressure air flow created in the Venturi area of the carburetor just above the butterflies. Give us a call, we’ll be glad to help! 1-330-630-0240.

+Summit Racing thanks for the help!

_Husky, Quadrajet pricing is what it is due to the labor involved to remanufacture them. They haven’t been produced brand new for many years, so cores have to be obtained, graded, cleaned,repaired and so on!

I'll sell you mine for $100

Thelegitrager I had to sell the car, engine blew. Sold the shell and tranny of the car.

Without a CNC machine and dozens of hours (possibly hundreds) of hours designing and fine tuning, you simply can't make a carb into direct injection without time and money. For a lawnmower I wouldn't even bother, unless its some sort of proof of concept or messing around.

Fast has one with 8 injectors

Yes this. If the carburetor were such and elite design modern race cars and record setting vehicles would still use them. The argument that a carburetor will make more power than an equal CFM fuel injection system gets old. Built a 572 CI BB with a Holly MPFI injection system and without high compression (runs on 87 octane) can make 800hp at the crank.

Old is outdated garbage

Hi Joseph Padron, Take a look at this link and see if this is the part your are looking for? It is called an idle stop solenoid! www.summitracing.com/parts/SMP-ES49/?feedback=1

Yes, thank you. I have already found that that is what i need. However I also just found that I am going to need a new carburetor. The whole that the idle stop solenoid gos in is stripped out. Again thank you for your help.

EFI is more fuel efficient. Plenty of evidence to show that, however there is no evidence showing a 1985 escort getting 40 to 50 mpg. If it was a diesel engine then I would agree with you. Now if your going slower than highway speeds I can see the 40 to 50 mpg but there is no way that thing is getting 40 to 50 at high way speeds.
