Outer Limits 4x4 Board

has anyone had anything to do with it , what it is worth and how well it works ? Im thinking of taking the gas off my Small block chev but only if i can get over fuel in carby problems in hill work etc .

No idea about the Holley EFI, but why are you thinking of getting rid of the gas?

firstly im trying to make it lighter and fitting new diffs i have to remove gass tanks just considering all options to keep back of car free for seat

Talk to Matt, he was looking into it for muza.

another option would be the holley "truck avenger" carb.
the yank mags rave about them. thay look the goods on holleys website.
i think they are about au$600 landed brandnew, not bad for a new carb.
it seems they solved the problems with sideslopes, up/downhill.
maybe its all yankwank?????
anyone know???

CRITICALLY ACCLAIMED!

Holley Truck Avenger Off-Road Carb & Power Shot Air Filter

I've been running a QuadraJet carburetor on the AMC 401 in my CJ-7 for several years and was getting a little tired of its performance at times. Even though this carb performs better than any others I've tried, especially after the countless hours I've spent fine-tuning it, it still doesn't allow me to c limb steep hills with bumps or ledges very well. I've learned how to drive through it, so to speak, but it has also caused some interesting moments in the past. When that big engine swallows all of that gas, either instant acceleration, or instant die-out is the result!

Now, along comes the Holley Truck Avenger. Bottom Line
On hill climbs, rough terrain and off-camber ravines, the 770 CFM Truck Avenger performed just as well as the 670 CFM version, which is exceptional. For sand or mud, there’s no question the greater CFM will come in handy. While I wouldn’t replace a fuel injection system to run any carburetor, there’s no doubt in my mind that the Holley Truck Avenger carburetor is the closest thing to fuel injection you’ll find! The toughest choice you’ll have to make is which one to get, the 670 or 770. If you’re running a stock 350 cubic inch or smaller V-8, I’d recommend the 670 CFM model.

dont know much about it myself but speak to v8grunt from the board...he's givin me some ideas about swapping out my quady to a holley 600vac to get fuel injection like performance...the key is to take the excess fuel from the bowl before it creates a problem...i think you have to run another pump or something.

I run a 383 chev V8 in a 40 its on Gas and runs good on all angels Efi or stay as is for me i may just put tank in back . Thanks for reply ill look into injection some more i think thanks again for input

My brother had Holley fuel injection on a fairly worked 351 Cleveland. The cam grind was such that it was still surging on the cam slightly at 100kph and it would wind off the clock in third gear (XB, top loader & 9").
Driven right it would still get 400-450 k's per tank which is reasonable for a fairly hot motor. They didin't do much better than that standard.

The fuel injection worked perfectly when coupled up with electronic injection. Once we dynoed it for the first time & set the mixtures correctly all he had to do after that was clean the air filter and change the spark plugs every 20,000k's. The thing started first time every time and did not suffer from the usual problems hotty engines have (fuel vapurisation, flooding, fouling plugs). The thing was totally reliable and never let him down for the whole time he owned it.

The only problem we had was we didn't fit a surge tank to it straight away & when the tank level was below a 1/4 it used to stall when we went around corners too fast. Fitment of a surge tank fixed that. You will definitly need to fit a surge tank if u r fitting to a 4WD.

We had to dyno it again when we rebuilt the engine but only minor adjustments were necessary.

Given what I have just told you this unit was built in the late 80's, so I imagine they are so much better today. I would not entertain the idea of using a carby these days a fuel injection can be relatively cheap to install.

The car was awseome to drive and embarrassed a lot of HSV's and XR8's,
even the odd Subaru driver would look twice.

Anyway enough bullshit, fit it it's good!!!!!!!!!!!!!

Has anyone any idear what they are worth second hand and what to look out for . I hadn't thought of the surge tank good point , great something else to do .

true but gives you a ball park, seriously from having a look at stuff, the avenger thing (if you want to go carby) may still be the go, plenty of good reviews and that jeep featured is doing some pretty crazy shite...

I had a quadrajet on my 305 chev, it would't handle any angles, so off it came and on went the holly with an " off road kit" supplied by 4x4 Engineers in Brisbane. Hasn't missed a beat since. Cost about $450 with the holly

Ok I think i might look in to that then i know a bloke in Albury paid some one to do some thing like that to his car he wasn't happy with result , ill ask him what it was .

PM v8grunt off this board. He sent me a detailed description a while back about how to modify a Holley.

I was too lazy to do it, and I bought a Q-Jet instead (which works perfect on all the angles I put my POS on )

Darren

spoke to holley yesterday

he's sending me an avenger carb to try out (lifes tough)

ill let you know how it goes.

id stick with the gas or go efi from a corvette

im told you can get all the stuff 2nd hand for under 1k

Man you must hate your job and contacts , I got a job in a 4wd shop hopeing it would quer my obssesive compolsive disorder for 4wdives it made me worse so i left for a job that pays more money so i can buy more toys . Any way im thinking keep the weight and money and stick with the gas its just to many things at once mabey look into it again later down the track. thanks guys input is always good .Probly should get back to putting my diffs in .
