Bill,

Are the float vent tubes the only problem with the Holley off-road?

I've been playing with some brake-line to connect the vents, but the hose is
a better idea. I'm trying to make a Holley 4160 600CFM on top of a chevy 350
(stock) work in a CJ7. Last trip (the first real off-road trip) I had to
gently lowered of a slope when the engine died om me.
I have a Quadrajet laying around as well, but that one has to be rebuild,
all the little thingy-parts are toast.

Brake flex line will dissolve in gasoline, use regular 3/8"
gasoline hose.
That is what makes the Holley have a bad reputation for not be able
to be tilted like climbing a steep hill. Their power jets are what make
them the only carburetor used on the drag strip, but it is also it's
weak point, it's diaphragm can't take even one intake backfire cause
many times by just a weak spark plug or floating intake valve. Although
Chris, here wrote there is a check valve that will cure that, but I
betting at the expense of it's performance. Another big problem with
Holley is their gaskets will shrink if left dry, that may happen in the
car, if the fuel pump check valve leaks and sucks the fuel back out of
carburetor. Plus those huge vent pipes that make run comparable to
injection will allow the gas to evaporate, drying the gaskets, then
usually it leaks, causing the owner to tighten the float bowl screws
squeezing what's left of the gaskets into the main jet channels, further
pissing off their owner. So, once it sits dry for an hour you must
install a new kit.

Bill,

The check valve will not hinder performance. It is basically a little ball
bearing that you put into the vacuum signal channel for the power valve. You
first counterbore the hole with a drill bit that they supply in the kit.
Then you set the baseplate on a flat surface and tap the bottom of the
counterbore with a Phillips screwdriver and a hammer. The "X" pattern in the
bottom of the counterbore will allow the vacuum signal to pass around the
ball when the manifold vacuum is trying to pull the ball down. In the event
of a backfire, the ball will push up against the gasket and small hole in
the main body of the carb and seal the power valve from the backfire
pressure. Also another note, the new generation of power valves are made
with a different diaphragm material which is more resistant to backfires.
The check valve kit works, and in fact, all new Holley carbs have this
implemented into them, and have for 3 or 4 years.

A note on the gaskets, if you use non-Holley gaskets, you're asking for
trouble. If you buy a kit and they gaskets are made of cork type paper, they
won't work long. The Holley kits now have a reusable blue gasket for the
metering block and float bowls. They don't stick to the carb like the old
brown and black gaskets do. They are also much more resistant to any
shrinking or swelling.
