Experience with Edelbrock air filter
 
I have a Kirkham 427 Street with Shelby 468 ci engine, and wondering if anyone has experience, both in fit and performance, with the 14" air filter below:

PRO-FLO HIGH-FLOW 14" ROUND AIR CLEANERS (black)

Accessories - Pro-Flo Series Round Air Cleaners - Edelbrock, LLC.

Thanks

TNTaylor,

With a 2" filter, you may be ok. Definitely not a 3" filter.
You can use a K&N drop base. They come in 2 drops. The piece is the same, just different cuts on the throat. Buy both and return the other.
With the drop base, you'll actually have to use a 3" filter, because otherwise the carb will suck the lid right down on it, choking the engine and denting the lid with the fuel vents.
My suggestion would be to get a Ford 14" air cleaner assembly (and a 427 sticker while you're at it :D), ditch the stock 2" filter and use a 3", and get a K&N drop base.
I think I just said the same thing twice. :JEKYLHYDE

Rodney -

Thanks. Where do you suggest I get the Ford Racing set up?

And 3" filter?

I presume I get 14" drop bases from K & N.

TNTaylor,

I think Ebrock actually makes a 14" round, 3" high filter. Try Summitracing.com. If not, get a nice K&N, and if SR or Jegs doesn't stock it, have K&N make it (from their website).
The K&N drop bases are also on Summit and or Jegs.
The Ford 14" assembly, try Cobranda.com, Scott Drake, finishline.com, maybe Cobra Restorers.

Look for an L88 base that was used on Corvettes , Chevelles etc back in the late 60`s . Repops are made today . That base is one of the best flowing bases available .... has just under a 2" drop and will fit a Holley 4150 with a few minor modifications ( cut off the PCV tube , plug it and some minor trimming ) . IMO , much better than the K&N base .
Tried 5 different drop bases on mine and didn`t find any that worked as well as the L88 base . I`m running that with a spun aluminum lid and air director I made with a 3" one layer/pass K&N element .... what they call their racing element . Has very little delta P across it . Those factory guys back in the late 60`s really did know what they were doing .... GM put tons of money making those engines run , take advantage of their research .
Also , do a search on Speedtalk on lids and bases .... there is a ton of info from serious engine builders over there on this subject .

Back in the 90's during the dail-in phase of my car put a call into K&N about the cfm requirements of the 468" their response was minimum 3"x14" with Extreme top it by the way is good for 500cfm. This engine now never lacks for air the filter sits up inside the grafted on much modified Harwood scoop.

Bobcat - where might I find the L88 base you suggest, as well as spun aluminum lid?

Corvette America - Online Catalog

Lid:
- Aluminum - Pretty much everywhere - any hot rod shop, many auto parts stores, Summit Racing, Jeg's, etc.
- You may want to consider a K&N xStream top as well, as pointed out by mdross1.
