jrichker said:I seriously doubt that there are more than a handful of people here that can accurately & completely explain how many flow circuits are in a carb and how they work. Simplicity is an illusion...

dragnazz5.0 said:power circuit, idle circuit, choke circuit, float circuit, low speed circuit, main metering circuit, accelerator pump circuit
its too much to type up what each one does exactly
dastang2 said:heads too, i'm talking the whole top end.

I run EFI on my stang and love it. I don't have many mods so I never played with the computer or much of anything other than a Mass Air Conversion, TB replacment, etc.
My brother has a 4-cyl/5.0 conversion. The car has a erractic idle to have just a E303 cam and jerks when you let off the pedal. Let's not talk about the Gas fumes. Obviously there is a problem with fuel enrichment or the lack of it.
I've had similar problems with my car in the past and a can of brake cleaner and a cotton swab fixed the problem. I just cleaned the element in my MAM. Every now and then it still jerks a little when I left off the pedal. I blame it on the absence of a bypass for the supercharger.
Back to the EFI/Carb. The reason for the swap is just basically simplicity. Everything on the car is old, wires, injectors, TB, intake. The only thing new is a MAM, fuel pressure regulator, and fuel pump.
After reading the replies, it may not be such a simple task.
I was just wanting to weigh the costs to fix the EFI or switch over. Money is always an issue as well as MPG these days.
vristang said:Carbs don't look that simple any more.
A carb combines several systems into one unit for convenience/packaging.
EFI spreads things out so that each system can be optimized. Then allows a computer to fully control each system.
dragnazz5.0 said:yeah, but figuring out how a carb works is cake work compared to figuring out how the pcm works.
I'd tell you to explain & try to tune something like an IDA 48 Weber downdraft carb. Then you would change your mind...dragnazz5.0 said:yeah, but figuring out how a carb works is cake work compared to figuring out how the pcm works.
no doubt all you see are the efi guys try to discourage someone from running a carb instead of helping them which would leave one to believe they themselves are clueless on carbs therefore they just talk down about themdastang2 said:did somebody offend you or something. :OT: really all the guy asked was what parts to get and how to start the conversion and not a bunch of mumbo jumbo crap about what fuel system is better than the other. they both have their pro's and con's. efi is much too expensive and has too many ugly wires and a carb system is the opposite. just trying to clear this thread up a bit because there are plenty of debates on many forums that cover this same topic and they will never end.

By the way, the IDA 48 Weber is used in GP sports cars for High Performance applications. $3000 gets you 4 of them and a manifold for your 5.0 engine. Great choice for racing something like an original AC Cobra or Factory Five Cobra reproduction.
My first experiences with carbs probably dates back before you were born. The first carb I took apart was in the ealy 60's and it was off a go cart with a lawn mower engine. Stromberg, Rochester, Carter, SU, Bendix, Zenith and a few that I can’t begin to remember. I have worked on carbs on everything from lawn mowers to sports cars, Chevy, Olds, Ford, even aircraft engines. I hold a FAA Airframe and Powerplant license and spent 11 years fixing airplanes. The only series of carb that I missed working on was the Weber carbs, which are probably some of the best made. All that, and I still haven’t seen one that can compare to the Ford EFI in our Mustangs when it comes to all weather, all altitude, no complaint performance and good gas mileage.sbftech said:no doubt all you see are the efi guys try to discourage someone from running a carb instead of helping them which would leave one to believe they themselves are clueless on carbs therefore they just talk down about them
5ive.oh said:Stay with the EFI, it's better on fuel and more driveable than a carb setup. But all it takes is a new intake and a carb, low pressure fuel pump, and a bit of messing with the vacuum lines. Of course the EEC IV will hate you.

im done arguing, I will stay with my holleys, you stay efi and atleast give someone the help they are asking for instead the constant bashing all you efi guys dojrichker said:My first experiences with carbs probably dates back before you were born.

Ok sounds good, all I can say is I read only 5-6 forums daily out of the 1000's of them, take a peek at the dozens and dozens and dozens of efi problem threads. But for the sake of child bashing, efi is the best, works better than carbs, is easy to fix when its broken and is the only way to go, happy?

We are not the only one doing a little bashing here.
