for rockcralwing with steep inclines and all that jazz EFI is the way to go, but i have heard good things about the holley tuck avenger but with a lil work and know-how the Quadrajet can easily and cheaper be made to outperform any of the high dollar aftermarket carbs
use the stocker for right now. It's ok but a little sloshy. The truck avengers look like a rock-solid carb though. When I switch intakes I'll likely use one.
ive got a holley now the old four barrel motorcraft crapped out and i cant find the parts. but i have head real good things about rochester q-jets. and my buddy is giving me one so im gonna run that. the holley isnt a truck avenger or nothin just a 650 cfm model 4160 street carb. and it doesnt do too bad in the hills. but could be better so im gonna try the q-jet.
yeah I think that holley made the truck avenger to solve the things that guys didn't like about their on-road carbs. The street carbs are just not made for off road. They're still a great carb, but start pushing the angle, or bouncing around over what's out there and it starts giving you crap.
what makes the truck avengers different, other than the modded bowl vent tube????.....ive thought about putting a hose on the vent tube going to a vented "overflow" container, so any gas that got out wouldnt start a fire somewhere...just a thought....
If you cant afford going EFI maybe getting a TBI Holley would be the way to go......if i can find a used one somewhere thats what i want to do on my 4x4....or you cab just go ***** out and buy a predator...
Another trick that I've read about on other forums is to turn the Quadrajet BACKWARDS. this puts the primaries in a better position for off camber situations going uphill or down something along the side. Do a search on it on the internet, I suppose I could drag up a link but I'd be linking to another forum, and probably get in trouble (Don't want anymore trouble with the admins...already lost my Saurian name cause of that... ). Tell me somebody else has heard about this.
When you're inclined, the fuel rushes to the back and the primaries start to starve. By flipping it, the primaries located in the rear now are not starved for their fuel, so it allows you to go at a much higher angle. The Q-jet itself is a great offroaded, this is one way to make it even better. I remember in one post it was called "Redneck Fuel Injection" when you turned the Q-jet backwards.

Yes, it actually works pretty good too.
You can also play with the float level in them to get it to lean the farthest to the sides and back without flooding out. Don't get it too low though, because then it will run out of gas instead of flooding out.
the truck avenger also has a set of jets that will allow up to 45 degrees of angle up or down, and 40 degrees side to side if I remember correctly. It also has something to keep the gas from sloshing around.
I run a regular holley with side hung floats, and it does fine, but I am more of an "idling" guy, so I can't say about how it would do at high rpm and steep inclines. At lower rpms, it is fine up to about 40-45 degrees. To me, that is more than I like to run it anyway.
yeah the stock motorcraft I run is surprisingly crappy. It cuts out at angles that I woudn't want to get out of the truck in, but other than that don't faze me, and I'm a weeney at this stuff.
Pfffffffffffffffft, you guys should get a carb that'll run upside down , but then again you'd have to switch fuels, but i think propane would be the way to go .
But on my mudder i run a holley 750dp, all mechanical, and so far i'm lovin it.
