im going to be gettign an air cleaner pretty quick for the 327, does the diameter matter? i was thinking about getting a little one for now, does it suck less or starve the engine of air? any facts would be great, btw this is a pretty stock 327 engine...

thanks dudes

it appears so...hmmm now the next question..do they make like an 8-10" diameter filter? i dont like those 14" beasts too much, they seem to bulky for a small block...maybe you guys could post pics of yours to give me an idea ...

thanks, Derek

I have a 14x4 K&N on the longhorn.....probably a little overkill, but with no inner fenders there is a lot more dust. I cant post from webshots, but there are some pics with a 14x3 k&N (last yrs filter)...... http://community.webshots.com/user/hotrodhorn

Here is my 350 w/ 14x4 K&N....

Stano · 02-03-2003, 09:45 PM

Heres my 14 incher. 14x3 I think. I have the tall valve covers so that may make it look a little different too.

Reumster · 02-03-2003, 09:46 PM

I run a 14X5 K&N on mine. Maybe over kill, but not if you don't clean it very often! LOL But I think that more important than size would be cold air intake set-up. The worst thing you can do is pull in hot air from your engine bay.

Big is cool!

Longhorn Man · 02-04-2003, 12:12 AM

I think the little dinkey ones look funny, and a 14 inch that is only 1 or 2 inhes tall looks way funny.
But that's just me though. Here's mine. This is the engine I'm running now, but in the old Longhorn.

Lippyp · 02-04-2003, 12:26 PM

Here's my dinky little K&N, does the job much better than the crappy triangular edelbrock foam thing that was on there before. Had to stick with a small one because of clearance issues with coil etc, besides I got it cheap at a show!

67cst · 02-04-2003, 08:43 PM

lippyp- you raised another question, im runngin points and of course there is a coil there, will this limit the diameter i can go?

Lippyp · 02-05-2003, 06:05 AM

The easiest way to gauge your maximum filter size would be to hold a piece of string on the centre of your carb and swing it around, shortening it until it clears everything, then measure and double it to get the maximum diameter allowing a little clearance for engine movement .

My V8 is in the I6 position so clearance is a little tighter than if it was in the normal V8 position. I guess I could have moved the coil and fitted a larger filter, but as I said I got the top and bottom plates cheap from a K&N stand at a show.

69sixpackbee · 02-05-2003, 03:00 PM

Heres mine on the 402..

Guess what it originally came on?
And yes it does fit the standard q'jet carb.

Longhorn Man · 02-06-2003, 12:19 AM

Personally, I'd swap over to HEI...best bang for the buck you could ever do.
And if you don't do that, at least relocate the coil so you can get a full size filter.

Lippyp · 02-06-2003, 07:01 AM

My K&N is 9" diameter btw and is supposed to be good for up to 250hp according to K&N's rep. My engine is pretty much stock apart from a Mallory twin point distributor and the Carter AFB as far as I know. (I am two owners down the line since it was built)
