Why do we install carbureted engines in our Fords?

[SteveC]

Steve, I'm sure that's what most people think it does but that's not how it richens the mixture for cold driveability.

hmm guess i still got some thing to learn then

I will explain what and how a choke works in the next day or two.

So I'm referring to the air cleaner wingnut and your thinking either the CVR or CER adjusting nuts.

So that makes me a liar and a poseur???

You know guys i think were getting a little off topic here. Fi vs Carb. They both have there good and bad points. It is unfortunate that good quality parts for us guys that want to stay orig is hard to find or they want 3 prices for good quality.
Maybe on my next project i would go with FI but my 70 will stay as orig as i can, but those little improvments such as elec ign and such are ok as far as what i want, to each his own.
The main issue and purpose of this great site is to help each other out in whatever direction we want to go.
I'm with SteveC i have a lot to learn but when we get in a pi$$ing match over half the topics that are brought up it dosen't help the guys that are just trying to get the info to go to the next step in there project.

You're right and I apologize.

Your a good man Rub, i would like to hear on how the choke works myself. I always though that closing the choke flap caused a neg air suction and pulled more gas into the carb throat.

Nah Steve,

The problem here is definition... example:

In electronics there are 2 theories... electron flow, and hole flow. One says the electrons move, the other says the 'holes' where the electrons fit move down the line...

Either one is plausable, just as your explanation has two answers, I think that Rubi is going to say it causes a higher vacuum signal. Either way, the end result is a lower (numerically) fuel-to-air ratio.

Two answers, same end result.

If you know that moving the choke plate causes an effect of F/A ratios then you really have the practical knowledge you need, without the theoretical (which is good to know but not as critical)

hth,

For myself, since it's not a daily driver anymore - swapping to efi is last on the list. I'd prefer to get the rest of the truck as good as time and money allow and then try the swap.

Having said that, if today the motor blew - my first stop would be the local ads for a 90's efi motor/computer unit.

I've got 185k on my 95 wore out 5.0 and it's about the last concern I have in life right now. It works all the time, I get 20 on the highway/14 around town and the whole truck only cost me 400.00 when my company replaced it.

Hey RobRoy...

FE's came with carbs...
While they may not be as fuel efficient as computerized engines they're simple and easy to work on.
Many of the guys here have put EFI engines in their trucks, several others have put desiels in as well.
Just about anything goes...
Well except for putting a POC chevy engine in a bump, that'll get ya flogged around here...

KaptnKA S

what if I put the 700hp BBC that I have here for my Camaro in a bump? I actually enjoy making ******* Child cars. If I ever do that, to make up for it, I'll put an FE in the camaro. We got a deal?

[bobbyinpd]

From the high performance aspect there is little advantage to EFI over a carb. a 300 HP engine is still a 300 HP carb or EFI.

The real advantage is the simple fact that 90% of those out there with an old carbed vehicle that like to fiddle with their motor and bolt on shiny parts and claim to have 400 HP really have about 200 on a good day. The reality is that a 250 HP EFI V8 will run smooth as glass and stomp the p*ss out of so-and-so's 200HP 400 HP chromed out and loud carbed V8.

That and So-and-so spent $5000+ on his 200HP 400HP V8 and, though sounding good, actually runs like a$$. Someone like me spends $500 on an EFI 351W, some 24lb/hr injectors and a used cam off craigslist and packs his lunch from stoplight to stoplight. I can also fire my EFI rig up when it's 10 below outside and it starts instantly, runs smooth and warms up quickly. It always runs exactly the same, no matter how hard I run it and has excellent low end torque and street manners.

Do you know how many times we saw this on the Chassis Dyno when I worked at Race Prep? all the time! And don't forget Fart can honda boy who put a turbo and Nawwwwwwwws on his civic and didn't do any tuning......We all had to spend a looooooong time mopping after that idiot....that's whay they sign a release before going on the dyno!!

[spartman]

I was gonna post about how to fit a GM TBI system easily to these engines, but after having read this thread I am gonna say screw it.

If you are interested pm me.

did some research in my auto class books and find out to some sort of the same wording that is what it does... so i learned something today

just going out on a limb to see if i understand but from what i understand when the choke is closed less air gets in so there is a higher vacuum and that pulls for fuel into the engine through the carb,

thou we arnt that far into stuff yet in class we are just removing and replacing engines in vehicles with the same engine. so its a take out and replace good parts onto the new engine and put it in
