No personal experience with the truck avenger, but from what I have read on various boards the results aren't favorable.
I can tell you this from experience, Carters, Performers, and Holley carbs are made for flat land driving. You can do some tweeking to them so they work better, but they still aren't up for off camber driving. Best bet next to FI is a Quadrojet.

I have a 770 on mine and I should have bought the 670 since it is too much for my motor to get the correct volumemetic efficiency so I have been fighting an off idle stumble. Other than that it works pretty good compared to a lot of other carbs I have had.

Looking through the Summit Racing mag the other day, it looks like the Low Rider carb would be good for us? Extreme angles, and bouncing around.....anyone tried it? Its a Holley 670

Holley's Low-Rider Avenger carburetors have an exclusive No Trouble design metering block and vent tube to prevent hesitation, stalling and fuel flooding at extreme angles, nose up, nose down, and side to side maneuvers. They also feature a No Trouble choke that ensures great cold starting. Their externally adjustable, No Trouble spring loaded needle and seats promote stable fuel levels for improved fuel control under all conditions. H.V.S. Annular Boosters provide an ultra High Vacuum Signal for incredible low and mid range throttle response and torque. Built in fuel inlet filter and Viton transfer tube seals ensure leak-proof no trouble operation. These carbs also feature chrome fuel bowls with side-hung floats to provide precise fuel control and maintain the classic Holley look. To top it all off, the Low-Rider Avenger carbs have a vibratory polished finish with gold dichromate hardware for a blingin' look.

I saw that same thing in low rider magazine and was wondering the same stuff. I was just too ashamed to say I was looking through a low rider mag.:darn:
I do dig the added bling!:thumb:

Thanks for all info, thought about propane and FI just wanted to go a cheaper route. Have access to 1988 truck that may be parted out but have concerns if that would be enough to feed my engine, plus it just didn't seem any less to go that way once you buy injectors, pump, new line, adapter and so on.

I have to chime in here. I put a home-made throttle body EFi in my cj. First it was on the AMC 304, and when that motor croaked I transferred it all over to a chevy 327. I did everything myself for a total cost of around 350.00 by buying all the parts off e-bay.

Cons- It idles too low, when very cold or totally wqarmed up the idle is fine. For ten minutes in-between the idle is too low and it will die when I come to a stop.
It won't pass emissions unless I keep the idle up around 1100rpm, this is no doubt due to my lack of a catalytic converter.

Pros- TBI only runs 15psi from the pump. Any fuel line will work.
Replacement parts are everywhere
Never have to file points again, and spark plug life is way better than before.
When warmed up the idle is rock solid at 700rpm. The pic in my avatar is my first attempt at the waterfall on Lost Trail. There was no idle problem, or throttle hesitation at all at that angle. I did end up getting strapped up the fall, but thatis probably due to my open rear diff.

What I would do differently. I would ditch the factory computer and run a MegaSquirt unit. This would probably take your total price closer to 600.00, but you get a lot more tuning options.

Good luck no matter which route you decide to go.

Gonna need a big block or a built small block to run that much CFM. Isn't that what Kevin was running?
I am running a 770 and it is too much for my built small block. I should have went with the 670 or smaller.

Right now my carter is a 600 cfm, And was thinking that even the avenger 670 was going to be too big for our elevation. I'm running a performer cam and intake, 64 cc trick flow heads, 10:1 compression, .030 bored, headers.

Saw a cheaper Holley FI kit that would support 270 HP, That is probably at sea level, Do you guys think that it would run well at our level. I don't think that I making any sense.

Maybe I'll just run it at redline everywhere so I can justify the ram jet 350
that I want:cool:

hey Joe... unless you want to go ahead and do fuel injection, just have a quadrajet rebuilt with offroading in mind. I have an old one you can have. Quads, when properly built will do better than any others out there for less, in my opinion. There are a few guyys in our neck of the woods who are really good with carbs that could set you up good.

If you want to go FI, go with a megasquirt system. it is far cheaper than most of the others, and infinitely tuneable.

Thanks for all the suggestions................now I'm really confused.:confused:

I think that I may try a quad for know, if that blows then maybe an avenger or FI.

If I can't do that then I'm going to part out the chevy and put all the money into my neon.
