to my loyal foxbody owners...

[moelll]

i've been noticing in all the mustang mags that all they seem to have is stuff for the 1986-93 mustangs and of course, 94-03 'stangs. all they seem to have for our beloved '79-85 mustangs is little more than accecories, decals and universal bodyparts. i feel that the carb'ed and CFI brothers from 79-85 are left out of the fun, neglected or seemed to have never existed until '86 with the introduction of EFI. what is so bad about the carb'ed and CFI stangs? are we considered second rate and not deserving of any recognition or is it that we're simply inferior to the great EFI 5.0?



i am wishing that someone will recognize this letter and reply to this. so the '79-85 mustangs could be noticed finally...

[moelll]

thats what i meant, there is barely anything for the older 'stangs

[Coupester]

It is simply a matter of the size of the market. There are many more bolt-ons for 86-93 cars because there are simply more parts to bolt-on. Let's face it, 86-93 cars ran much stronger than the factory than 79-85 cars, 85 5spd cars being the exception. If it wasn't for the EFI revolution of 5.0 cars during the early 90s, fox bodies would never have reached the popularity they have today. For anyone looking to improve the performance of a 79-85 car, look no further than your Summit catalog. The same performance parts used in the 60s will bolt right onto the engine of your carbureted foxbody...

I love carbs. A carb NEVER left me stranded. Yeah it may have been out of tune and what not but it always worked. The best part was that only I knew the dance of the gas pedal to make the car go. Best anti theft deterrent made :-)

[Evil86lx]

one of the main reasons is emission laws. their are a whole slew of parts to be thrown at efi cars ans still pass the sniff test. dont get me wrong you can throw a paxton on a carbed car but the factory carb would never support it and then you would have to change the carb and then well it wouldnt pass the sniff test.

in areas with no emission laws their are plenty of fast carbed cars, and the 79-85 cars are preffered. even though they usually get a aero nose on them.

kyle

[f4fntm]

Supply & demand. Where the demand for parts meets a certain level, manufacturers will step in to meet it. QED.

Therefore:

SN95 body kits are popular cuz those cars are newer and new car owners don't usually go for hard-core engine modifications. Also, demand for engine parts is kinda low for 4.6s (even after 10 years of production) cuz they are not as strong and easily modified as the 302.

87-93 performance parts are everywhere because: a) there's a lot of them still on the road; b) 87-93 cars appeal to racers (they're plentiful and cheap); and c) the 5.0 motor is considerably superior to the 4.6 as a hi-po platform.

Four-eyed cars are relatively few; most have been scrapped or are in the hands of owners without the funds or desire to put big bucks into serious upgrades. Ergo, less demand and correspondingly less supply.

My response? I have a stock '85 for restoring and an '89 to play with - best of both worlds.

[plstktnkr2]

As far as mods go I am doing a carbed 4.2 engine for my '83 conv complete with holley 4bbl/headers .(yes it all fits) Also any 4 eye can (with a lil effort and reaserch) can put an EFI on ,which makes it more tune-able for max power. CFI cars are not that tune-able due to no adjustments on CFI unit(or at least none I have found on my 84)

I have to respectfully disagree. One of the best things that ever happened to cars were computers. An eec 4 computer is a very primitive version of car computers. The eec 4 system is so easy to troubleshoot and work on, that all but the most novice of car people shouldn't have any problems.

Because of my computer, my car fires right up every morning without touching the gas pedal, idles near perfect, fuel mixture is always perfect, and I can go VERY long amounts of time without tweaking or tuning anything, such as you do constantly in a carb'd car. (and yes I have grown up with carb'd cars all my life)

Simply put, the 79-84 engines were inefficient powerplants worthy only the basic block, if that. The best thing IMO that can be done to the early cars is to fuel inject it, and convert it to a late model roller motor.

I do like the 85 engines, though, and if you must retain carb, then 85 is as good as it gets.

[negusm]

My bitch isn't so much with the computer as it is with the crappy sensors that need to go every whitch way in the car. Sure it fires right up now and gets better gas mileage and more performance...but there will be that day when it doesn't and you can't figure it out standing at the side of the road.

My '96 Probe GT worked fine and was a very fun car to drive until sensor after sensor started to crap out. It left me stranded far too many times and was at the dealer far too many times. I vowed to never own a computer controled car more than 5 years after being new.

Even out of tune, a carb will get you where your going. Sure, I've been stranded with a carbed car but never because of the carb. I've been stranded in an EFI car because the @$^@& sensors couldn't tell it that the engine was cranking over or it was getting air or fuel.

My turn to disagree :D

Most of the sensors will still allow the car to run , even when bad. (known exception for sure being the TFI )

You can also bypass just about any if not all bad sensors by just unplugging them and the car will run in "limp home mode" which is timing at 10 and fat.

Also any Ford with EEC made after 85 has a check engine light. A simple paperclip of piece of wire will allow you to jump the terminals and flash your codes on the check engine light.

Thats what Sport Compact Car magazine is for :D

[negusm]

GT350R, Do you know how to do that for a Honda, Toyota, Chevy?

I don't really mean to put down EFI. It's here to stay and has its uses. To me it doesn't seem to "age" gracefully. I just have more "fond" memories of carbs and they seem to age better. Sure they get sloppy but you tend to know when they need a rebuild and a tune up. I just have not had good results with OLD cars and an EFI setup (not just my Probe). Call me bitter and jaded and you'd be right.

But anyways, I know I added a bit of flame bait with that first comment. I will recant my earlier statement that a computer screws up an engine. They have their uses (performance, automatic tuning, mileage, etc)...and they do help in troubleshooting. I just wish they were more RELIABLE. <rant>God...they need to put DOUBLE sensors in everywhere and when one fails, the other takes over and then tells you about it so you can get the first replaced.</rant>

I'm just still bitter about my Probe since I loved that car to death. It ****ed me for the last time and after it got fixed (crank sensor), I drove it straight to CarMax.

Side note...I had that damn car to three places (dealer, and two diff AAA shops) after it wouldn't start and each one got the "bad crank sensor" code from the CPU and they still couldn't recreate the problem. They changed everything under the sun and cost me well more than $1500 by the time the three places were done and it was never fixed.

[m j]

only I knew the dance of the gas pedal to make the car go.

how hard is it to slowly depress the pedal once to set the choke, then release pedal and turn the key.
vroom, high idle

I can go VERY long amounts of time without tweaking or tuning anything, such as you do constantly in a carb'd car.

total BS, you do not have to tweak or tune a carb'd car. you are talking out your backside.
the idle mixture screws were buried behind metal plugs to PREVENT mindless meddling
efi uses the same archaic distributor wearing parts as us old carb guys
so what is it that you think i need meddle with?
do I have to diagnose clogged AIC passages?
I love the way the rpm stays high forever during gear changes with efi. :roll:
I just wish they would have given my 85 the extra compression you guys got
even at 8.5:1 I smoked your 9.2:1 engines
efi helped with emissions
after 85 the wiring harness was redone and the engine compartment looked neater

I do like the 85 engines, though, and if you must retain carb, then 85 is as good as it gets.


so 85 proves carbs are as good as efi?
it gets so much better with a few bucks spent.
the throttle response of a carb is so crisp compared to that efi long runner that runs outa steam at 4800rpm

to the origonal poster,
what exactly do you need that isnt available?
I see a virtual plethora of parts available.
efi guys can only dream of being as fast as a carb $ for $

[m j]

the carb is probably way passed time for a rebuild after almost 20 years.
if that is the case no amount of 'tweaking' is gonna help it.

[v8only]

The bottom line is a non-computer controlled vehicle simply WILL not run as good as an efi-computer controlled for as long.

Meaning my efi-eec 4 86 mustang will fire up, start, and run identical and consistently for miles and miles and miles. No surprises, no idle problems (ok, sometimes I get "the surge") etc etc. The computer brings consistency.

The simple fact is that a non-computer controlled car gets out of tune quicker and faster. After a while you get rough cold starts, carb problems are common, etc etc. We can debate this until we are blue in the face, but the bottom line is that no right minded individual will argue that a carb-non ecu car will stay in tune and run as consistent as an efi-ecu powered car.

Having said that, carbs do have their place. $ for $ it is a hell of a lot cheaper than efi for racing purposes, + the simplicity of an early 60's/70s carbed vehicle is wonderful. IMO though, 79-85 is NOT a good year for smog/carbed non ecu cars, and any of those cars from that era would benefit from an ecu/efi setup (assuming we want to stay smog legal. If we don't want to stay smog legal, then that is a whole other ballgame)

[Matt K]

First-almost everything for an 87-93 car will work on a 79-86....what do you mean no parts available? If you have a roller cam 302 (or even if you don't) the hardcore parts are the same. Suspension & brake components are interchangeable, entire driveline as well. Interior can be (if you convert). Yeah there isn't quite as much as far as body kits & hoods, but most guys here are kind of purists anyway!

To the anti-EFI guys...I have 300,000 miles on my 90 GT. The only sensors I've EVER replaced were my oxygen sensors & coolant temp sensor when I overhauled the motor (@250,000 miles). With 3.73 gears, Heads/cam/intake/30# injectors I still get up to 25 Mpg on highway trips. It starts everytime. It doesn't surge (Ford Idle Air adjuster works wonders, as well as a dyno-tuned chip!). Yeah, I can only run low 13's on crappy street tires & a suspension setup for handling, not hooking up, but it's fast enough & hands down the most bulletproof & reliable car I've ever had!

He was talking about parts for his CFI car..

You know what that is????

I thought you spent 30k on the car, 13s!!!!!!

kyle

[Matt K]

Dude-I don't appreciate personal attacks!

Yes I do know what CFI is & it's best left in a damn dumpster as far as I'm concerned! It doesn't stop him from either swapping it to a carburated setup or newer style fuel injection. It doesn't stop him from throwing on heads, headers, pulleys, rebuilding the engine, swapping the cam, transmission, etc. you get the picture!

As far as my car goes, over 12 years of ownership & many different modifications over the years (a continual process!) you'd be surprised how quickly the dollars add up! Especially if you change the entire way your car is built (i.e.-started to go for drag only, but wasn't practical for a daily driver, so decided to go for a more streetable car). Are there faster Mustangs than mine-you better believe it! Lots of my buddies went faster (for a very short period of time). I'll take a low 13-second (on 225 Sears tires!) street car I can drive anywhere over an 11-second car that breaks axles, transmissions, gets 10 Mpg, etc! I put some slicks on my car & bump up my timing and my 13-second car becomes a 12-second car, but you don't care about that do you. I posted an honest in street trim dragstrip result, just as my car runs everyday-I don't care what you think of it or me, but you don't even know me or my experience so don't be a jerk to me-thanks!

[Evil86lx]

I'm not attacking.. only ribbing a little.. you know joking around.. testing the waters on the new guy..

And yes in my opinion cfi is crap, but i know a few people who like it, wierdo's.

You should try a little more junk yarding, parts trading, etc etc etc

that is a whole sh#$ load of money to throw around and then feel that the car is worn out and needs replaced. When someone reads that you spent that much money, and the car isn't that quick it looks really fishy.

And yes 79-86 parts are hard to come buy. A little better now that some of the company's are making parts for them. It sucks but I'm hoping for a better future four us four eyed fabs..

Sorry, My dads 66 F-100 has gone around the clock over 4 times and has the original carb and still runs points. On its second rebuild though but still runs the original 2-V carb on it. Routine maintenance is something that is held near and dear to a lot of people like myself.

Computer controls are a fact of life and not going away any time soon. I honestly dont mind them but I much prefer my old carburated cars and I'm only 29 years old. From working in a garage there is something to be said about the simplicity of a carburated car. Thats why most all on this site hold onto these ideals because out cars originally came with a carbuerator. Reminding us of simpler times and tried and true engineering. Carburators have been around since the dawn of the internal combustion engine and modern day fuel injection has been around for less then two decades, constantly changing and getting more and more complicated as time goes by. Usually unnecissarily. I agree EEC IV is one of the simplest and adaptable engine managment systems ever. But they can still baffle and cause tuning problems that are not easily remedied without an extrordinate ammount of time, money, expensive parts and equipment. Just because a computer does all the hard work for you doesnt mean carbs are old news. Tuning them is simple and can be easily learned. Computer controls have made people lazy but they continue to sing their praises knowing nothing about the basics that make tuning an engine a fulfilling prospect. Just because they bolt on parts and go fast doesnt mean they are really knowledgable about the simplest of automotive fundamentals. But then again a lot of people prefer to go that route and there is nothing wrong with that. The added complexity is just a bigger challenge to master to some. But when they slam the carb I think they simply do not know how to properly tune one. Manual adjustments may seem archaic to some but give simplicity, tunability and peace of mind to those who know their potential.

How many times have you heard of someone having never ending fits trying to get their EFI mustang to run right, get fed up and just put a carb on it? Then turn around and say it was the best thing they ever did. I have. Three times. I helped with two of the conversions.

But getting back to the original topic....

Most of the fastest cars in drag racing are carbuerated. Most only run EFI because the rules mandate it. One must simply look elsewhere for parts then a mustang oriented catalog. Just because our cars arent mainstream or modern doesnt mean we are left out. I would argue that a Holley 650 D.P. is more tunable then modern day injection setup. Having said that, it has more potential then any fuel injection setup and upgradable for less then 1/2 to 1/4 the price. Non 5.0 mustangs should never expect extreme performance(Turbo cars not included) but can tune for a bot more sportyness without much hastle. Its just a lot harder to do with a non mainstream car without an aftermarket following. The rewards should therefore be that much greater.

Old engineering to me is just more fun to drive.

I'm sure many would disagree.

[Evil86lx]

Iv'e done both. And i can appreciate what both have to offer.

But since i am a certified VW tech, and i spend 12 hours a day behind a scan tool. I'm a little partial to EFI
And i like boost. I did a blow through carb set up and it was a pain in the ass. Messing with the carb hat, milling this milling that. And this was only 11psi. If it was a efi set up, change the injectors, FMU, a little dyno time and bang your done.

But of course i did decide to stay carbed on my vert. Maybe I'm just trying to return to the simpler day's as well

Routine maintenance is something that is held near and dear to a lot of people like myself.


The routine maintance was one of my biggest points. In my younger years, I did not do maintance. I drove my efi mustang for at LEAST four years straight, without any more than 4 oil changes (stupid I know) at 15-20k a year. I did not tune it up once in that four years, never replaced one vaccum line, never timed it, never replaced the spark plugs wires, cap, or rotor. It had at least 130k at that point, and would fire up and purr just like new for that whole four years, until I got wise enough to start maintaing it.

Don't get me wrong, I come from a carb backround. My beginnings in automobolies started when I was 16, about 13 years ago. My first car was my mothers first car, a 72 maverick with a 302, and that little ol 2100d autolite 2bbl. I have been through a 74 318 carburated dart, a 67 mustang, and a few others, so I am well knowedgeable about the carb'd cars, I can infact appreciate simplicity (I still have the maverick!!)

I feel though, that for every day driveability, and the ease of mods, you just can't beat efi. WIth a carb car, your bolt ons usually consist of carb, intake, headers/exhaust, maybe pullies and you are pretty much done without going internal. WIth efi, you can bolt on till your blue in the face, and each step brings a bigger smile.

However, on my 72 mav, I am dropping in an 86 hi output 5.0, and will likely convert it to a 4 bbl, just because I miss having a carburated car.

Having said everything, there IS one thing I miss dearly, the SMELL of an old carburated simple car. You just don't walk by a car nowadays and get that sweet smell of gasoline and exhaust fumes any longer. Call me crazy, but I have been guilty of walking by and "smelling" the sweet old car smell from the garners truck.

nothing better than a carb'd 5.0 fellas and ladies!!
my car is about 98.8% completely mechanical like the old school muscle cars!

holy crap 8O back from the dead.

[frankiesaysrelax]

Carb vs EFI debates always amuse me.

For every dead TFI module there is at least one carbed 302 with a stuck float pouring gas out ot the vents. :P

I've dealt with all kinds of engines over the years, rotary, piston, aircooled, watercooled, gasoline, diesel, carbureted and fuel injected. I must say the tuneability and driveability of EFI just can't be beat. Have fun changing jets at the track with your toilet bowl carb, LOL. Or having it run poorly because of a change in elevation or maybe just the weather. Sticky chokes are always good for belching black smoke and wasting gasoline.

However, I miss cars like my '65 Chevys (I had 4). Three vacuum lines and a couple of wires. There wasn't a whole heck of a lot that could go wrong. If the car didn't run it wasn't too hard to figure out why. And those damn things pretty much always ran.

However, if it wasn't for EFI, we wouldn't have things like 500hp 302s with buttery smooth idles that your grandmother could drive to church on sunday if necessary.

I miss carbs kind of like the way I miss my old IBM PC XT. Good old DOS 3.0 never crashed on me once.

[fordfreak300]

When people remove their EFI and got a carb set up and use a comparable manifold (as close as can be) and teh right sized carb they seem to gain about a second on their E.T. next time you open up your MM&FF look at all the really fast guys and see what they are runnign EFI or carbed? Then wonder the reason why... The last time I tuned on my carb was two times ago at teh track and that was probably a year ago or close to it. And that was only because i was changing jets. I can set my carbed motor up the track, I don;t needa dyno to burn a chip or maf or any of the other elctronic stuff to replace or spend money on. The idea behind fuel injection was not performance, it was for emissions. And for the record I pump my gas pedal once and my car starts and idles. I have no choke. People will debate carb vs EFI for years to come. You can make either fast as it has been proven. It is all what you are comfortable with. I prefer the carb my self.

[85Gt4bbl302]

like i said before nothing like a carberator!

when you remove/ add injectors, you need to bleed the fuel rails
theres no bleeding carbs, theres usually gas still stored up within the carb, slap it on turn the key and the car starts right up!

Thats why I like carbs. A carb usually degrades gracefully over time and you're like, "yeah I know I need to get that carb fixed, tuned, whatever but I'll do it next week". For a consumate procrastinator, carbs are the only things to have.

:lol: yeah... no need to bleed them. Just remove the fuel pump relay and crank the motor over once. The pressure in the line is gone then. :D If it has been more than two hours, there's no need to do anything at all. The pressure bleeds off over time. That's why the system is primed before each startup.

The last time I opened a MM&FF all of the fast car's are DFI turbo or blower car's. No carb's their.

That is a very biased and false statement.

kyle

[Capri50]

next time you open up your MM&FF look at all the really fast guys and see what they are runnign EFI or carbed? Then wonder the reason why...

There is no reason to wonder, it's not really an accurate statement.

Go to any NMRA event, and there is an overwhelming amount of EFI vs. Carb's with the big boys. Super Street outlaw, Outlaw 10.5, Hot Street, Drag Radial, Real Street, etc. Over the last few years, there is a noticable increase in the EFI turbo/blower setups vs. carb/nitrous from yester-year.

the reason's why are numerous. Tuning EFI is no longer black magic like it used it be. The repeatable, consistant results is what people want. Data logging from the computer has become an invaluable tool for getting the most of a combination.

On my last dyno run, I had a lean spot from 4800-5400. I went into my laptop, increased the fuel mixture by 4% in that RPM range, and it was dead on next pull. Please explain how I would have easily corrected that on my old roots 144/carb setup without affecting the rest of the AF.

I remember back in 1986 when the EFI motors came out. People thought the sky was falling. Little did they know the 86-93 EFI mustangs would have started the performance revolution that has people running around on the street with 500-700 RWHP combos with perfect street manners.

I am not knocking carbs. I played with them for 15 years. They are cheap and easy to tune. But it drives me nuts when I see people knock EFI and haven't had any tuning experience or understand how the eec-iv works.

The way I see it is this.... Carbed= for those who don't want to mess with the comp, good daily driver, and perfect for a natuarally asperated monster with big cubes. EFI= Good for people who like comps, and have the ability to mess with them through a labtop ect.... also easly modifided for a blower.......

one of the main reasons is emission laws. their are a whole slew of parts to be thrown at efi cars ans still pass the sniff test. dont get me wrong you can throw a paxton on a carbed car but the factory carb would never support it and then you would have to change the carb and then well it wouldnt pass the sniff test.

in areas with no emission laws their are plenty of fast carbed cars, and the 79-85 cars are preffered. even though they usually get a aero nose on them.

Yup! I think the main thing that got the EFI car mods going was the fact that you could change a few things and still pass the test.
If you live in CA, then all parts you add/change must be CARB certified even if your car passes the sniff test.
There are a LOT of CARB certified parts for the EFI cars. Sometimes I wish I had an '86 just for this reason. Then, I am perfectly happy with my '85 so the lust for an '86 usually passes.
