I know FI is the way to go but don't have the bucks for that right now. So what carb is good for the 231 V6? Also, is there a writeup anywhere to modify it for off road? I've been told the Motorcraft 2100 series is good when modifed. Any comments?

Thanks
Keith

Go find a Q-Jet from a 4.1 Cadillac. They are by far the best for off-roading.

Or a qjet from a 3.8L Buick Station wagon <IMG SRC="smilies/biggrin.gif" border="0"> That's what mine came from. Still sitting on the workbench waiting to be installed though.

I'd like to know more about this too, but for the sake of argument let's say I'm sticking with a 2 bbl carb on a 304.

most FSJs come with motorcrap, er, craft 2100 series stock. they're good carbeurators for offroad abuse. what's so special bout a qjet? i hear people ravin about 'em, but why are they so cool?

The qjet on off-cambers wont run out of gas in the bowls. They can take the verticle driving. DONT NOT GET A HOLLEY they suck off-road.

everyone around here runs q-jets turned around backwards on the manifold. The things will idle sitting on the rear bumper, or until you lose oil pressure and seize the engine. Don't get a Holley or Edelbrock! They Suck, my truck has a Edelbrock and it stalls on the slightest hill unless I have my foot in it.

Good Luck <IMG SRC="smilies/bounce2.gif" border="0">

I won't agree with this. I have run a Holley 390 on my 3.8 since 88 and it has worked pretty good for me. I have done some work to it to get it to work off-road but no amout of work is going to get it to work like the Q-jet. If I had to do it all over again I would go Q-jet for sure.

I haven't touch the motor craft on mine, except ofr the idel and mixture and it runs Like a champ. It runs on off cambers greatI have had it running at about 90 degrees when i was gettinjg flip back over and it ran until I was back on all fours no problems

If a 2bbl is all you need get a motorcraft, bolt it on and go. It is definatly one of the best offroad carbs and is easy as hell to work on. If you need more carb get a Q-jet.

now for a question: what years are you guys getting the small Q-jets off of??? i have a 795cfm sitting on my 4.3 right now <IMG SRC="smilies/biggrin.gif" border="0">

I run a holley 390 as well and it actually works well once you lower the float just a hair, and extend the bowl vents so gas doesn't flow into the carb on angles... I have even thought about putting it on backwards just for craps... Oh yeah, with a fuel pressure regulator, you can crank the pressure down to like 1 0r 2 and it will really be sweet on the trails, however, it wil suck on the road, so get one that is easily adjusted at the end of a trail ride. Oh yeah, the q-jet is still better, im just making what i have work for me... Hugh

holley makes a carb that looks like it would be great for this application.
Model 4360
looks like a quadrabog but better, no gay metering rods
it is around a 450 cfm 4barrel

good thinking on the old motorcraft flat top. is that the old 4 barrel like used on early 60s mustangs?

I'm running the MC2100,on a 258 no problems here to speak of.
Bought a remanned one, bolted it on(with adapter, spent a little time adjusting the mixture, and it runs great!
Havent had to mess with it since.

Seems to work fine off camber, and on inclines, and declines.

A buddy of mine rns a webber(same motor), and following me up the same inclines his seems to bog.

For the money I'm very happy.
