i was considering switching from the stock efi on my 88 gt to a carb setup. Aside from the obvious new parts that i would need( intake, carb, throttle linkage), i was wondering if anyone else could think of any bugs that i might run into. I was also wondering if just using an adjustable fuel regulator to turn the psi down to like 8 or so would work. Someone told me that this would blow the electric pump.

i dont agree on the tuning abilty. with a carb you can set up primary and secondary jetting. plus by losing the gay efi intake, i would have the abilty to remove my valve covers without pulling off the entire upper intake. and as for gas mileage, i could not honestly care either way. the way i drive, bad gas mileage is always the result.

Think about it though. You gotta mess for HOURS on end screwing with vacumes and everything, changing jets, ect., all based off of the a/f and power.
With EFI, you just hit a couple numbers, and it's prefect. Set for any type of load, rpm, fuel, pulse width. It's a lot easier.
If the upper intake's getting in the way, here's an idea. Go flip through Hot Rod mag. There's a red 66 (?) Mustang with a twin turbo 302 under the hood. Check out the manifold design there, and modify it for your needs.

I get 26 miles a gallon with just a spring swap and it takes me about 1-2 mins two unscrew 2 screws and replce a spring and put another one in and rescrew it back in. I think that is pretty dang easy.
JEEP are you running a carbed setup?You running an EFI setup?Hell are you even running a stang?Then how and what do you know about them?
To swap over to a carb and its a great idea to you need the intake,carb,and distributor.You can either go with a points setup that i dont recommend or you can use the DURASPARK 2 setup which consists of 4 wires and a small little brain box and youre on your way.
Carbs do offer more tuning capabilities and their cheap to fix,tune,and maintain.Not too mention if tuned right and by right i mean specigically for either performance or economy a carb is comparable to efi.
Go for it a carbed setup rocks!I love carbs and wouldnt have it any other way.

one leave the real questions ot ppl who actually know what there talking about.
as far as the carb setup go with what socalledkilla331 has to say. . you will need a regulator for the carb so you dont feed to much fuel to the carb. a carb i think has around 6 psi. a efi setup has around 37 stock. youll destroy that carb with that much pressure. you should be alright with the switch as far as problems go. but please leave the wiring in the car. you never know if you sell it if someone will want the efi setup or you might want the efi setup again.

I pity you......
Does it really matter if I've got a stang or not man? I know what I'm talking about and fuel enrichment is fuel enrichment by either EFI or carb, no matter what the motor.
EFI's limitless tuneability,smooth power delivery, and more power/torque makes it a winner in my book. With plug/play technology coming out, and the fact that you can build and tune a standalone for any motor pretty much for under $300 (MegaSquirt).....I really don't see how you can shun EFI over carb.

I think most carbs are happiest between 4 and 6. For whatever reason the guy who built my friend's 318 put an 8psi pump on it and we were having a hard time tuning the carb (edl 600). He told us that all chrysler pumps were high pressure like than and that we'd need a regulator. Sounded fishy to me, especially since I don't have or need a pressure regulator on my 360.

[QUOTE=nemethjames1] i live in cali, and i got the efi setup on my 88, if i went to carb, i wouldnt be smog leagle would i?[/QUOTE] hell no it wuldnt pass not in cali.that state sucks when it comes to emiss. you have to takr that elect pump out the tank run a hard line.instead .go with a holley ,blue or something like that.get msd box for ign.and msd dist.unplug computer harness,change coil.

good decision on the carb i love carbs. and he already chose to convert it and he is confident with it so dont give him sh*t. and we have been through this about 10000000000000 times in the past month, so dont even try. do you want to keep egr or not?? holley sells a great street legal carb (the street avenger) and put an edelbrock performer intake on it. if you dont want it go with a demon carb and an edelbrock air gap manifold . get some heads on it and you will be putting down some f*ckin power. im looking into doing the same thing so thanks for posting this . i need to know the finicky sh*t too.
