    I just switched to a holley 600 carb on my 83. I was wondering if all the hype about them being worthless on the trail is true? If anyone out there could give me some pointers or tell me how they like their holley it would help me out.

    The biggest problem with Holley's is the front/rear mounted fuel bowls - on any good incline, they tend to flood out. The first thing to do with a Holley is to put a piece of hose across the two bowl vents, and cut a small hole in the top of the arc.

    they also make an extension for hte jets, so when your at an angle the jets are still sucking gas. I had a holley and hated it. every little hill and it would bog out. tried the tube on the top and the jet extensions and it helped a little bit but i said funk it and bought a quadrajet and love it. on the street the holley was basa$$ though

    This is bad news for me guys :( I have a 750cfm holley 4150 series carb on my 454! Does anyone know how to sure the holley incline problem that Pugsley points out?

    If not, anyone need a Holley? ;) Will trade for anything that does not bog!

    Does anyone else smell BFGs burning???

    no guarantee in my personal experence, mabye you'll have luck mabye not, but the quadrajet is the closest CARB to fuel injection

    There really is no way to cure the Holley's bogging problem - extended vents and angled jet plates will help some, but not really enough to make the Holley a solid performer in the dirt. Quadrajets rule the rocks, plain and simple.

    I can tune a holley with the best of them. but I could never get one to keep from flooding on a steep hill. I'v tried the slosh kits and mounted them every way but upside down and still had problems. Al though I could improve their off road capabillties. Having a carb that would flood out and stall just when I needed the power used to piss me off to no end.
    The Carter AFB type carbs also suffer with the same problems as the holley.
    From my experience the Q-jet is simply the best carb for off road. I even bought an adapter plate and put one on a Bronco with great results. I know other ford drivers that run them also. There are more than a few fords out there that should be sporting the " Built ford tough with Chevy stuff" bumper sticker.

    I have had no problems with my Edelbrock but I'm building a Q-jet for mine.

    Two words: Quadrajet....wait (counting fingers...)
    Anyways, short of going to fuel injection, a Q-jet will be the best carb for inclines and all around off roading. The small primaries also help your gas mileage.
