My buddies just talked me into going carbed with my 93 5.0. I already got a 331 stroker kit on the way from eagle and i want to top it off with a carb setup. I just want to know if it is easy to convert from efi to carb and if anyone has done this and what u think about it.

Thanks guys

Your buddies are on crack! IMO that is. Tell them there are places they can get help for that. Your EFI not only saves you gas, but it automatically changes air/fuel mix at different altitudes, temps, and load requirements. It gives you the best power for the situation. It tells you when something is wrong (don't know if thats a good thing). Sure a carb can be easier if you know how to adjust it correctly, but EFI will give you more power and better gas mileage at the same time. Especially since you already have it and don't need to spend money to convert it to EFI.

Carb will be cheaper to build and can be tuned to make close or the same power as EFI. you will suffer slight loss in mpg but if you know how to tune your carb to different conditions it will work fine.

I've made this swap and the carb to EFI swap several times. You have EFI now, swapping to carb will cost you more money. A carb can make the same horsepower as EFI but it will not make near the same torque through out the power range. Fuel economy will suffer. But its your car, do what you want.......

My close firend just swapped to carb on his 95 GTS and lost 6 mph in the 1/4. He is so frustrated and cant seem to get the carb tuned correctly for his application. He just said that in hind-sight he should have left it alone.

[BCR93stang]

ya i am not worried about the gas mpg as long as it makes power. This is not my daily driver car so i want to go all out. Ya i thought you would make more power off the carbs. Hmmmmm i might rethink my doings be4 i waist my money. Thanks a lot guys

Carb = cheap and simple with very few problems.

EFI = expensive headache that for a lot of people isn't worth the added MPG

With that said, if everything is working fine, there is no reason to switch to a carb setup. I now have an 88 with a carb setup and an 89 with EFI. For street drivability the EFI is really not much better. My EFI with moderate bolt-ons doesn't like to be below 1500 rpms at part throttle even though it is tuned well. My carb setup runs just fine at low rpms and easily has more torque (partly due to it being on a 351) and the same or better idle quality. The EFI setup gets better gas mileage in town, but there isn't much difference on the highway.

People that say carbs don't make the same torque at low rpms are the same people that put dominator carbs on their street/strip small blocks. If you do the math and put a properly sized carb on your car you'll make plenty of low end torque. For a 302 that means a 650 cfm or smaller carb.

Well you must have something wrong with your car because mine is highly modded and I have no problems in any rpm range but I do have a PMS and can tune it to run perfectly.. I would never go to a carb..

[ryans88gt]

obviously a pms helps, otherwise it wouldn't be for sale. Didn't need a $1000 piece of equipment to tune my carb. Case closed.

Why do you have to be a fuckin wise ass? As you would put it if its for sale it works. I can name a thousand products that are for sale but dont work for shit.. It seems no matter what is said you will have something to say.. What ever dude I like what I have and I my self would never use a carb. I bought the PMS and a wideband to have total control of my tune and do not have to use a dyno to tune my car. 2 or three trips to the dyno and its paid for. So if you change your combo you can tune it yourself and not have to guess if it right..

if done right neither efi nor carb is cheap to tune. carb may have a slight advantage pricewise but for precision and adaptability efi cannot be beat. case reclosed :lala

I agree.. I also would like to have the case reclosed but you know who is gonna respond with the extensive experience and knowledge that he has and it will not be closed. Bottom line build your car the way you want period...

[JBIGBOOTSY]

Ever price a nice race carb? ,not some holly double pumper your uncle jetted way too rich, then ground off the choke horns. But a real race carb? I know people with over 1800 dollars invested into one carb, and while it mabe possible, you woulden't wanna dirve with it on the street.

IMO if you really had a lot of expirence with carbs you would be one of the first in line to say they arn't easy to tune.

[5literJeff]

Just keep in fuel injection imo. I went carb on this car but it was originally a 6 cylinder so I wanted something very simple to swap in. If i could do it over I would do EFI.

No milled off holley here, I have about an hour on the dyno and a 650 mighty demon, didn't really seem that hard. The jets and power valves were already dead on out of the box. The squirters were and still are a little too small for my engine, but I didn't want to mess with them. The only thing that needed adjustment was the idle circuit and a little fine tuning with different air bleeds. Cost about $600 altogether including the price of the carb. Runs 11s with a flat hydraulic cam and drives great on the street. What more could I ask for? 10s you say? Well I am swapping to a solid roller this winter, we'll see how much that wakes her up. By the way, you can use a wideband O2 with datalogger on a carbed car too and tune it without being on the dyno.

Sure people spend $1800 on a carb, for a few more tenths when they are already running 8s or better. If anyone has a $1800 carb in their street/strip car, they just have money to burn.

[powerjon]

for some reason, i always thought that efi was easier/better...

i built a carb corolla and the throttle response was 500% better. i just didnt like having to tune it every run.

No its not that I was commenting on your stupid remark saying if they sell it that it works.. What a stupid thing to say.. Lets just agree to disagree ok asshole..? lol jk am I? yes I am, Not, Maybe.......

[joe 5.0]

guys its great that you offer your opinions to save people money but the question at hand is and what most would like to know is what would it take to do a EFI- carb set up

parts needed wireing and so on

[JBIGBOOTSY]

dizzy, duraspark, malory pres reg, carb intake, and a lot of brainwash.
