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 climb 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. Being
the skeptic that I am, at first I thought it was just another
Holley with spring-loaded needles and seats. Although I have never
personally run a Holley off-road, I hadn't ever heard great things
about how their carburetors perform. In fact, just the opposite
has been the case. Many people have ended up switching back to
their stock carburetors or have bitten the bullet and gone to
fuel injection.

One look at
the Truck Avenger tells you that this is not your ordinary Holley.
The first thing that catches your eye is the one-piece vent tube,
designed to "eliminate fuel spill-over during extreme maneuvers."
Other not-so-obvious features are a built-in fuel inlet filter
and Viton transfer tube seals, clear site plugs for easier float
adjustments, spring loaded needles and seats, an adjustable vacuum
secondary, High Vacuum Signal (H.V.S.) annular boosters, electric
choke, and metering blocks designed to "eliminate fuel spill-over
through the boosters at extreme angles."
