whats the best carburetor to use for off-road use?

[sweetpeet]

I have an amc 360 4 barrel in a jeep cj5 and I need a carburetor for it but Im not sure which one is the best one. can I get some advice and recommendations based on how well they function for off-road use such as high inclines.

I'm using an Edelbrock 4 barrel with an offroad kit. I also went with an electric fuel pump and it works well for me.

I'm running an old AFB, but until 'Betty' is fully ready for off road, I think an electric pump is great advice.

whats an offroad kit consist of and how does it help?

I think the Edelbrock's CFM is too high. I heard it be more around 400-500 for better offroad throttle response. since its alot of stop and go.

what would you say the advantages and disadvantages between these carburetors are? ford motorcraft 4350 and holley 90470 (truck avenger) and for the sake of comparision the Edelbrock 1826 (thunder series 650cfm electric choke).

The offroad kit is mainly a spring kit that keeps the float from shutting down on steep inclines and declines. Minor adustments in tweaking the right amount enough to keep the needles on the float bowl open but still closes when the bowl gets full and keep it from flooding out the carburator.
In comparison with the one's you mentioned, i like the way the Edelbrock performs however, if i had known how much of an alcoholic this thing was gonna be , i would have picked the Truck Avenger series on a 600cfm instead of the current 750cfm.
On the intake choices, i would probbably switch to the Airgap series to help the cooler fuel delivery down the ports as opposed to the current Performer series. I'm still undecided if i will go that route instead of a fuel injection , ultimately, fuel inection will be the best upgrade but the most expensive as well.

I've read that too in some high end magazine Steel, with regard to injection being the most venerable fuel delivery method for off road, pity I don't have the resources to go full tilt boogie on induction, but so far so good.

I'll always take an old Rochester Quadrajet for off-road.
The centrally located float bowl keeps the tipsies away.
The only trick to them is following ALL the adjustment steps on the carb kit instruction sheet and using the specs for your particular carb number.
One off a 70s blazer/PU with a 350 should be close.

I've always wanted to work a propane conversion into a carb. From what I've heard, the carb. end of the set-up is only a couple of bills. + tank, lines, and such. Propane has NO stall on inclines. It might be worth looking into.
