Brian;

I don't have the spec sheet with me at the moment, but there are multiple Donaldson options that would work. EASILY handle the airflow of a 350.

Tomorrow night when I get home I'll post up the options. About $120 retail for a brand new Donaldson housing and filter.

The other reputable industrial air filter is a Mann-Hummel. If you can find an industrial junkyard, look for forklifts and airport ground equipment for used housings.

Donaldson filter can be obtained in the US. This catalog is really helpful. Has parts for the filter assy, mounting bands, elbows, connectors, precleaners etc. The FPG model is what is similar to what's on my HJ. Landcruisers used in mining industry converted to these filters due to their hard life.

Here's one I purchased today. Sitting on the fender of my 45.... FPG070017 is the model. The FPG is the series.

Look closely behind the fender. The small tube pointing down at an angle is a dirt/dust drain and is the only part that must point down. The rest of it can be rotated just about any which way along it's longitudinal axis. This drain tube is one of the features of the new Donaldson filters. It's supposed to make the filter element last even longer.

And here's the details on it. This is a kind of big model, but it has a 3" outlet, which matches the inlet on the turbo for this truck.

I purchased it locally at Albuquerque Filter for just under $120. In addition to the filter, I've got an intake cap, and a 90 degree tube attached to it.

Further note: this setup will, I think, be installed under the hood of Dad's 40 (with a 3B/turbo in it--see the sig for more info).

In addition to what you see here, there's a clamp that goes all the way around the filter and mounts it to the truck.

How about the adapter that fits on the carb (in my case a QuadraJet)?

Good question. I think I'd just measure the diameter of the ring on your quadrajet, and buy a rubber hose that fit it. Alternately, you could fab one out of metal pretty easy if you've got a plasma cutter and a welder.

All I see online are air cleaners that attach directly to the quadrajet. Apparently, hot rod guys don't like to use anything that isn't cheap, round, and chrome. There looks to be more options at JEGS?

All you've got to do is get a tube from your Quadrajet, after that it's nothing more than a big tube to the Donaldson.

Dan, I downloaded the Donaldson catalog, and did the CFM flow specs, etc.

Your FPG070017 is made of plastic. I'd prefer metal, so the closest metal version is the G065551. Price is very close to the plastic version. It's an inch less in diameter, and not quite 2.5" longer. I think it will work out better on the fender, because that allows the vacuator valve to be placed further to the rear.

I'm going to make cardboard templates of both units, and see which I like best. Unlike your 45, I have marker lights on my side apron that I'd like to clear, and I'm running a second battery, so the plumbing to the carb has to be between the battery and the master cylinder.

Prices are as follows:

G065551 $123.40 (this is the metal unit, but does not include a safety filter)
G070017 $129.78 (this is your plastic unit)
G070018 $128.68 (this is like yours, but has a 90 degree outlet, which I'm curious why you didn't go with this model?)

The downloaded catalog gives part numbers, but no illustrations, for the accessories, like bends, hoses, inlets, etc.

-------------------

The question was asked about the benefits of a Donaldson air cleaner. In addition to what was posted, I want a cold air package, meaning I want to bring in fresh, unheated air to the engine, rather than intaking hot engine compartment air. This can be done in several different ways, not just by using a Donaldson air cleaner. I also want to have decent fording ability. Instead of running a snorkel and fitting it to an internal air cleaner, a Donaldson not only makes more sense, but compared to snorkel kits it's a lot cheaper.

....Apparently, hot rod guys don't like to use anything that isn't cheap, round, and chrome....

Yeah, LOL, that's what's on there now.
