Can Carbs actually work well off road ??

[Big Hank]

I am getting my 350 ready to go in the MJ. At the moment it has an Edelbrock Carb, and Torquer Intake.

I don't know much about carbs, except for they never seem to work off road. That is just what i have seen.

Is there anyway to run a carb off road and be able to still crawl, stop on hills, or even shut it off on a hillside.

I have been looking at some Holley Pro-Jection, but the price is way more then i want to spend at this time. So basically, can i make a carb work off road?

Weber!

Is there something that really seperates the weber from the edelbrock? Just wondering if you might know. I am assuming there must be a major difference.

The main thing that makes one carb better for off-camber things is the shape of the bowl. The two best are weber and motorcraft IMO.

I put the weber 551 on our 89YJ and the off camber, extreme angle stalling problems went away, has to do with the bowls and the float placement and the way the float is hinged so it does not shut the supply off at any angle. I always wondered why they did not use a free floating float that had a top fed bowl but what do I know about carb design...

We built a cabtruck at the shop a few months ago, 327, t400,doubler, etc...we had been swearing by the two barrel motorcraft carb for offroad, but we really wanted a 4 barrel....so we tried a holley truck avenger carb...works great, will idle on a incline and doesn't load up, money well spent in my opinion. pro-jection is a pain to set up also and i wouldn't bother getting it unless you bought the really expensive set up. We ran the cheper of the projection on a 360 motor , it worked great around town and on the trails. But by the time we got it set up to idle and respond correctly it apparently was running to lean, because as soon as we hit the highway with it 20mins into a trip it starved the motor and burnt several pistons. I also have had several memebers of our local club try the pro-jection and none are very happy with it, most went to a throttle body factory GM type set up.

I like that throttle body FI setup and would have considered it for the YJ but I had no idea what other parts I would need to make it work, 2.8 and 3.4 GM motors out of S series blazers and pickups are all over place and they all seemed to have them around 86 or so.

doesnt weber make parts for edelbrock carbs. if you look the weber symbol is on the edelbrock carbs

Yeah, it was 86 on the S series when they changed from carbs to TBI. It is really simple, its almost like a two barrel carburator except it has two fuel injectors. I still might have an extra intake manifold/TBI off of my old 89 Blazer at my parents hose unless my dad gave it away, i had the rebuild kit too. Of course you'd still need the computer and wiring harness.
