That bay sure falls into the catagory of beautiful would like to look it over closer and hear the story behind the build.

Bringing this thread back to life to specifically ask about air cleaners. I've read hundreds of posts on the topic here, but I found this thread as i was looking for ideas as to what i'd use for mine.

Here's the issue, my motor needs to be lifted a bit due to oil pan clearance issues, easy enough. The air cleaner i'm using today is an oval OEM piece with a 3" K&N (E1963), aand it fits perfect. When i dyno'd the engine, Ford Racing 392, it made more power in this configuaration that without a filter at all. And when i ran the stock paper 1 7/8 or whatever stock is, it pulled almost 40hp. I know paper is the worst, but it got me thinking. I see quite a few pics on this thread alone with what appears to be 9" air cleaners with 2" or so height elements. Is it possible that's enough? I can't imagine it would be. The math says a K&N filter would need to be 3" tall with a 14" diameter for a motor at roughly 500hp at 6000rpm, roughly.

My issue goes back to my oval air cleaner with a 3" tall K&N. I'd love to keep it, but can't due to the leading edge hitting the hood. The next size down K&N is at the factory 1 7/8 tall. Is that enough?

Jeg's and Summit Racing supply drop down air cleaner base for this issue. I am having trouble downloading the link using my phone. But you will find a photo if you search.

The current air cleaner base leaves only 1/8" gap before touching the spark plug wires.

If you raise the engine you'll not only decrease clearance for your air cleaner, you'll change driveshaft angle and may need to modify your headers.

I had oil pan clearance issues as well, but solved them with a custom oil pan. Sump is about 80% of the length of the pan, with kickouts on both sides. Bottom of the pan sits 1/4" above bottom of frame rails. That's a much better solution, IMO.

100% agree! The C4 rear diff is fixed and the current angle is nearly flat now, so a little angle would help probably. But the sidepipes are a different issue, too close for comfort if I raise the engine a half inch or more, especially with rubber mounts.

I am going to just purchase a lower profile pan and be done with it. The Ford Racing pan is too low and is already listed here in the classifieds section, unfortunatley that's $600 that Summit won't refund on. Cobras aren't cheap!

That Ford pan is listed as 8.1" deep. Take a look at Armando's #406 pan - it's listed as 7.5" deep, so 0.6" shallower than the Ford pan. Armando can also make you one with a longer, but shallower sump if you need to gain more clearance than that.

I was under my car yesterday and I'd say the sump and kickouts are pretty much full length, except for the rear-most 3". It's relatively shallow on my BBF, with the bottom of the pan above the frame rails, and still holds 11 liters. I also had a bung added for an oil temperature gauge. Armando's price includes a crank scraper and the matching pickup.

Looks good, I had to go with a Performer RPM intake to get some additional clearance. At the engine dyno I had them swap between the original paper 1 7/8" filter and the K&N 3" filter. The paper filter dropped almost 40 HP. With what you have, I'd say the surface area is even less than the 1 7/8" filter on my 22" oval air cleaner. Do you know if you're losing power? I'm just trying to wrap my head around what the correct element size is as we see most cobras in the 351+ CI range.

Thanks for the reply!
