I have a chevy truck 350 with a spacer very mild cam performer intake with some headers and an edelbrok 1406 carb. I know fuel injection would be better for wheelin but I dont have that kinda money yet. For the time being I was wondering what I can do to my current carb or a carb I can get for cheap and do a few "tricks" for cheap to make it better for wheelin as I am currently laid off. I have looked around and its prolly been discussed but I cant seem to find it any help would me much appreciated. Thanks:pinky:

edle brock make a "offroad" kit for those carbs but regaurdless edlebrock carbs suck for 4x4.

i have had great success witha holley dual fed, no transfer tube to starve one bowl and flood the other. but your all around cheap and most effective carb is going to be a qjet. just yank all the smog shit and linkage bars off and run it.

How has that setup worked for you? Qjets are hard to setup if you don't know what your doing correct? I hear the are and there are so many adjustments. But there good once setup right. Just going off of what I have heard

there is no need to "set them up" unless you are building a race or monster motor.

i love the damn thing, i have mine on my lumpy truck, 454/465/203/205/60/14bff/4.56/38boggers. right of the bat they are bigger than you will typicaly need. but they run smaller primaries so you may see a slight mpg inprovement. but they dont have lot of the flow and flooding issues that eddy and holley have.

the holley i ran like i said was a dual feed, not a double pumper but it the bowls were spereated and did not transfer fuel when tilted. it would still flood out ocasoinaly but not like your eddy or a single line holley will.

like i said strip all of the vacume pots, vac lines and linkages off and you can just run it like you would any other carb.

Well its time to go to the salvage yard. anything to keep in mind when lookin for one?

there 4 common ones and they range from 305[725cfm] to 454[850cfm] any one of them is going to work, you may be better off with a smaller one but i have over run the bigger holley's in size with no ill effects before [350 with a 770cfm holley]

a typical 350 only needs 650 ish cfm from a holley or eddy. make sure to grab the throttle bracket too, it will save some stupid headachs.

I would prolly get one off a 350. Will it bolt up to my current setup or do I have to get on of those dammed adapters?

Performer intake with a 2 inch spacer? Over kill I know it was free

it should have both bolt patterns on it already.

Q-jets aren't wonderful for rockcrawling or any off-camber 4 wheeling. The reason is that they have a VERY small float bowl.

It does have the advantage that it is in the direct center of the carb so that there is some resistance to changes in camber, but this is offset by the fact that it is so small that the bowl will empty quickly - and will die much faster if you uncover the gas tank sump. This may be as short as a few seconds.

The guys on the fourm I typically go to say this but there not into wheelin or anything. Would a bigger cab then what I need have bigger float bowls?

i dont know about the bowl size issue.....

as far as off road, meh if that what you what to belive go for it, everybody has there reasons for running what ever carb, there are kits out there that will make qjet even better for offrad but i dont know what they change. i love my qjet at all angles, stock.

Ditto. I've heard great stuff about the Holley Off-Road Truck Avenger carb. I would look into that if I were you. :skull:

Lies.

I've had my buggy on end and on its side many times (enough so that oil pressure starts to be an issue) and my Q-jet has always been fantastic. I've never seen any carb come close (including Holley Truck Avengers), most people ask me what kind of injection I'm running.


Search here in the Chevy section, you'll find lots of info on Q-jets.

My buddy has one and at part throttle on the street he says it "hesitates" And he has done almost everything to it.

I'll take your guy's word on it as you have more experience with wheeling then they have. Just trying to make sure I get all opinions before I go get something.

Wrong. A q-jet runs extremely well off camber. Next to fuel injection its about the best option. Mine runs practically vertically for extended periods of time and completely vertically for a short time.

I have no idea why someone would think that a q-jet isnt a good rockcrawling carb....
:shaking:

I would recommend taking the intake off the engine when you get the carb, it may run better than a Performer with a spacer for rockcrawling applications.

I'm not sure what your saying here? I have the performer intake and 1406 carb. So change my intake? :confused:

You mentioned you were going to the salvage yard to look for a q-jet. You also were not sure if your performer intake had the right bolt pattern so I'm suggesting that you buy a stock intake and q-jet at the salvage yard. Personally, I would run the stock intake anyway for crawling as the stock intake runs fine from idle to 4k rpm.

Just my .02

I'm not sure what your saying here? I have the performer intake and 1406 carb. So change my intake? :confused:To be a little more specific, a Q-Jet mounts on a spreadbore intake unless an adapter is used to mate it to a squarebore intake like under your 1406.

So, if you go with a Q-Jet, also source a factory spreadbore intake, an adapter, or an aftermarket spreadbore intake.

BTW, ask around. Some gearheads give Q-Jet stuff away. The carb, too, though rebuilding a Q-JET can cost over $100 if the throttle plate must be rebushed.

Oh I got you now Ill prolly get an "adapter plate" for the time being I wana rebuild it with a 383 soon

My edelbrock performer intake is drilled and tapped for both square and spread bore applications. No need for an adaptor plate.

dont by a stock in take, all edlebrock performer and rpm intakes have both patterns, unless you have a very old one.

Your buddies that cant get a quadrajet to run must not have much patience or deep pockets... saying that the float bowl is small and the engine will die off camber when the fuel pickup gets air is about the dumbest thing I can imagine. blaming a carburetor problem on the fuel system? I have wheeled for years with quadrajets and have had very few problems, most that were my own making.

dont adjust the secondary air doors, theyre probably fine the way the factory set them up....
you dont need a choke, be a man and nurse the motor to life in the morning. let it get warm before you drive.

a quadrajet will outperform any carb out there offroad. EFI is the only other option, and if the fuel pickup where uncovered on an EFI engine, the motor would die even faster as they dont have a fuel bowl.

Tell your buddy hes full of shit, and not to piss down your neck and tell you its raining.

I have a newer one last year I got it. Ill pull it off when I do the spring swap. If it doesn't have holes for it I'll just get an adapter plate like said in previous post. I'm currently trying to get my hands on a Q-jet. but people on craigslist are shady as fawk some times:mad3:

I don't remember saying they cant get the Q-jet to run. I do remember saying they couldn't get the holley ta to work well at part throttle. I am taking your guys word for it.

I don't run a choke on the edel. Its under construction as we speak as I dont have a job (stupid economy:shaking::mad2::flipoff:), but I do intend to make it my dd.

I dont let anyone discourage me in anything I do I just like getting opinions of others who may have some advise and more experience with doing things twice.:D

In the mean time, for about $15, you can get the "offroad" needle and seat kit for your edelbrock. These, and a few pieces of small rubber hose will get your edelbrock performing twice as well as it does now in terms of offroad performance.

Not a 100% solution, but a 15 minute/15 dollar fix that will help for the time being.

I did these mods to my old edelbrock a while back and it solved the problem of flooding over rough/bumpy roads at speed, and peformed noticeable better off-camber.

When you're looking for a q-jet at the junkyard, make sure you get one off an OLDER rig...none of the electronic controlled units.

THANKS!:beer:

Get an inline fuel pressure regulator asap and dial it down to 1 for low speed offroading, especially with the Edelbroch. Since we are rehashing this for the 1000th time.

THANKS!:beer:

wow, i wish some one would have mentioned the offroad kit sooner, maybe in the 1-2 postes, :rolleyes:

It was I just forgot about this thread cuz I been reading others and workin on the vessle
