Installing a K&N X-Stream air filter on an Edelbrock 1407.

Post by robroy »

Good evening!

Perhaps a project this small wouldn't normally be newsworthy. Yet when I began, I hadn't yet found the K&N instructions, so I started to photograph everything. Now I don't want my documentation efforts to go to waste!

Up until now I'd simply been resting the K&N X-Stream Custom Assembly on the Edelbrock 1407--I hadn't fastened it down properly. I noticed that I received a sack of odds and ends with the K&N but figured it would be self-explanatory when I got to this stage; it wasn't (for me at least)!

Y'all can click on any of these images to see much larger editions.

Here are the K&N instructions:

Image

Here's how it had been resting. I screwed the long stud in to the carburetor just to make guide the assembly for easy filter re-installation.

ImageImage

And here are all the K&N doo-dads! I put letters next to each of them anticipating some expert FORDification advice on how K&N intended the parts to go together--then I found the instructions. I would have never figured it out on my own, without the instructions. Not fully shown in the photo is a neoprene gasket that goes between the filter's bottom plate and the carburetor.

Image

This doo-dad sack had this label on it:

Image

Before the instructions, I'd reasoned that the rubber washer was probably related to the similar cavity in the top of the filter. I eyeballed it in a primal fashion, waiting for my brain cells to jolt in to formation--they did not.

ImageImage

This photo has no meaning, yet the focus came out too nice not to post it.

Image

Here I'm on K&N Step 5, using the straight edge to set the proper height for the lower nylock nut.

Image

And for K&N Step 6, I measured 1 and 1/4" out from the nylock, and marked it with an opaque paint marker.

Image

I then applied a fine machinist's instrument for a precise cut.

ImageImage

After cleaning up the end with a file and running a grade eight nut over threads a few times to ensure their suitability, I re-installed the stud (using an included jam nut at the bottom, to hold it down in the carburetor). After re-setting the nylock nut to the proper height, I got to K&N Step 8--I placed a steel washer on the stud, which rested on top of the nylock nut.

Image

Then the mysterious rubber washer finally appeared, right where it seemed most natural; here I'm finishing steps 9 through 12.

ImageImage

The finished product! It will be nice to run the engine without the air cleaner tap-dancing on the carburetor! Not to mention the profound peace of mind I'll feel while driving slowly through a vast, dense cloud of duck feathers.

Have a fantastic weekend!

Excrutiatingly detailed!!

Nice looking motor, BTW...
A 72 F-250 Hi-Boy "project" ( that means sitting untouched for 3 or so years)

And a little 94 F-150 Flareside, 7" higher and 35's...

Good morning WaynaFerd, thanks for replying!

Thank you very much!

I have an insane, humor-based impulse to document every detail of things, and am actually trying to skip over as much stuff as I can stand to--for example, I didn't even mention the old gasket that was on the carburetor that I replaced with the neoprene gasket, or the minute finger pressure that was required on the brake cleaner can to yield tiny amounts of solvent to dissolve the glue that held it down!

Thanks! In case you haven't happened to see it before, you can read all about it here: 390FE (406ci) for #50, built by Tom Lucas at FE Specialties.

WaynaFerd, thanks for your excellent reply!
