Has anyone ever run the holley truck anvenger carb? Summit part # 090770.
I am thinking of putting one on my 400sb in my CJ and would like any info
Thanks Jay
 
Good carb from what I hear. Going to Crakersneck in a few hours and my friend is running one. After this trip I can tell you how it does

Then you never had a q-jet. ;)
 
I have a friend with one and he hates it. If its tuned for off-road it doesn't work right on the highway and vice versa. I put holley projection on mine and its great. Took me a weekend to install it all, but nothing is better than fuel injection. You can find the kits used on ebay for about $400.
 
I tried one an it was the worst damn carb i ever had, If you
know some one that can really set up a Quad like Rich said
there is nothing better.

I have ran with several people who run Q-jets. Some very high end ones, mounted backwards and the whole 9 yards.
The Truck Avenger runs at LEAST that good, maybe better.
Realize befor I bought it I would not give you a nickle for every holly ever made, I despised them. Now though I own 3 of them.
 
I've heard both arguments about the T/A. I know the 670cfm is a little big for a mostly stock 302, but Holley has adressed that issue with a smaller cfm model. Some of the first models were being sent back to Holley for recalibration. I believe they swapped metering blocks so it wouldn't run so fat on the bottom end.

I built my own carb out of a #4776 600cfm double pump. I had a friend of mine who used to build carbs for Blake Carburation help me blueprint all the circiuts. I also drilled the base and airhorn for 4 corner idle. Installed spring loaded needles and seats, and bowl vent similar to a TA. The recipe he gave me for the drillings were for a 9.0:1 late model stock carb. I installed the carb adjusted the 4 corner idle mixture and fine tuned the idle speed. Those are the only adjustments I had to make, the float level and jets were on the money. Its clean and crisp like a race car, and will idle at some pretty wild angles and still have throttle response. After building my carb I know know why they get close to $1k for some of those racing carbs.

you're the only person I know who has gotten one to run worth a damn out of 6 different people...maybe there's a reason they pop up on ebay...
 
JUst got back in from Crackers NEck. Andys Carb didn't let him down on any trail. He is very pleased! Uphill, side hill, did well on them all. he is happy

Rich I agree the Q-jet is an awesome carb, I run one for years untill I got a little more extreme in my wheeling, then it didn't work for me. But then again, I didn't modify it at all. Many things can be done to them to make them just as good as a holly TA

I disgree about nothing better than fuel injection. Fork Lift fuel, BBQ grill stuff is awesome! Cheaper than FI, easier to install and cheaper to buy!
 
I use to build a lot of carbs for the dirt track guy around here. I know holly & Q-jets pretty good. Hollys are great carbs in there place, On the road.......
the so called truck av. has been around for years.... in Boats, Holly found out there carbs are crap off road and were losing the market to other carb co.
so thay took there marine carb and boxed it as a off-road carb..... nothing new... I have never been able to make a holly run good off road. its eather a up-hill tune or a down-hill tune...side hill..... forget it....
Q-jet and some motorcraft carbs are the best for what we do....
I ran a Q-jet for years with no prob. I just went with HOWELLS TBI kit for my YJ with a SBC and love it.... runs any way you put it...even on its side :D

save some $$ and get a Q-jet or come off some $$ for a TBI or TPI and be done. anything else is a waste of good $$$

There is more to a Holley than just putting a $30 kit in it. I've also built a bunch of Qjets. Nothing wrong with them I just don't prefer them.

Then since noone has mentioned them I will, Edelbrock(Carter). JUNK!!!
 
Holley has to many plastic parts, an fuel bowl adjustments sux,
give me a good quad, or a edelbrock. The motorcraft 2150
is an excellent 2bbl. also.
 
Just a .02 from me and my truck avenger, it was way too much carb for my 6 cyl (duh...) prev owner had put it on there. I replaced it with the MC2100 in my case. (Which means I have a truck avenger sitting on the shelf collecting dust waiting for someone who wants to buy it!) :)

I will say it ran in about any direction my junk was faced (uphill/down, side, etc)

I had my regular Holley running well. I had added the off-road needles to a regular carb. and did some basic adjustments, and it would run to what they specified it would run.

Problem is its NOT hard to exceed a 30deg side hill. or their limits up/down even if temporarilly. Factor in multilple angles at the same time and your running like poopoo...

I was happy it was running as well as it did, but realized the jeep was capable of a bit more... If i was still running a carb, I'd run the 2 bbl holley like Sam, same benifits just less to worry about... also the truck avenger has side hung floats while the 2100 uses a center hung.

If your wheeling 3-4 trails its probbaly fine, if your wheeling 5 stuff carbs do have limits...

BTW: im selling my holley for under $100 might be a cheep way to try it out before droppin 400 on a new one... -mike
 
/I always have the same question about this, and have never had a good answer in return.... Why drop big bucks on a Holley or Edelbrock on a Jeep when the tried and true and cheap MC2100 remains the reigning champion of carbs for the Jeep I-6 and V8's? $30 gets an MC2100 at teh junkyard, another $30 gets a rebuild kit for it. They are so simple to work on, they are reliable, and run in damn near every position. It's not called poor man FI for nothin'.
