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? |
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.
