hey guys, im lookin for a new airfilter for my 1965 289 with stock hood. its got a holley 4160 carb and a regular HIPO style aircleaner on it now :ic::

I want to put a taller filter, and i dont know what to order! i went to the site of the cleaner i want to buy (S&B) and they offer a base that is either 9/18ths or 1 1/2 inch drop base...wtf? so i said 1.5 with a 4 inch filter...will this fit under my stock hood but still be larger than my filter now? here is the one i built on their site, can someone help me out? http://www.sbfilters.com/custom_asse...=217%7C79-9464
thanks guys!

 

How about a K & N filter?

Like mine.

 

i like the style, but its not big enough (tall i mean)

 

It's pretty tall compared to a stocker. I can't close my hood all the way in the rear now. The bad of the hood sticks up about 2 inches when the hood is shut. I could tell that it added some pep when I installed it.

 

To see your height you have to play with under your hood get some plastercine and make 5-10 clumps place on air cleaner close hood and the plastercine will be squashed and you can work out your lowest point on your air cleaner add a safety margin and that is the highest air cleaner you can have.

 

This is a fourmula from a K & N filter catalog for air cleaner selection. The answer is the area of filtration required for an engine of a specic displacement, CID, and RPM. The formula goes like this -
A = CID x RPM/20839
A 351 CID engine at 5500 RPM would need about 93 square inches of filtration. To get the height of the filter use this formula -
H = (A/D x 3.14) + .75
The area A (from above), divided by the diameter times 3.14 (pi) plus 3/4 inch.
So a 12 inch dia air cleaner element would need to be about 3 and a 1/4 inches tall.
When I played the off road game, we multiplied the answer by 1.5 to handle the dirt and dust accumulation.
