i am in the process of getting my 81's 300 modified soon, for better peformance etc. i am installing the offenhauser intake, with efi exhaust manifolds, and a edelbrock 650cfm carb. i am now looking for an air cleaner for her. i have an old edelbrock open air cleaner. i have really been interested in doing an oem ford snorkel type air cleaner setup, for a factory type look. i have an eye out for a dual snorkel from a 82-85 ford mustang 5.0l. but i do not know if will properly fit in my truck. if you guys have any other options i would be greatly appreciated. thanks again for everything

 

How I would do it because the carb is off set you would need to know the OD of the filter assy. you are planning to use to see if it will fit the carb and not hit anything like the HVAC box.


BTW if you are looking to get rid of the stock filter assy I would be interested in it asI have nothing for my 81 300 six.

yeah i was planning on doing that , but i was hoping someone had did the same thing. yeah i actually have 2 81 air cleaner setups so i may sell them. i have not really thought about it though lol

 

You might be able to use a centered dual snorkel air cleaner or add a snorkel to a stock single inlet style such as Gary Lewis did. Using a spacer
(between the carb and the air cleaner) might solve the off-set issue if there is clearance for the added height. I had to have a 1 3/4" spacer machined to re-install a factory air cleaner after installing my HEI distributor which was taller than the factory distributor. It is simply a machined aluminum "ring" along with a longer wing nut stud.

 

yeah i saw gary's his is what gave me the idea to use a snorkel air cleaner again. i will have to test fit alot

 

I assume you saw the page on my web site: Air Cleaner - ???Gary's Garagemahal

 

oh yes gary i did that is what gave me the idea . did you install on the v-8 or the 300?

 

It has yet to be installed, but it'll be on the 400 for Dad's truck. Engine should dyno at 500/500, and I figure that air cleaner should support that level of power just fine.

 

oh okay i thought so. do you think the mustang or a 5.0 liter truck air cleaner would work with my setup?

 

I don't know what diameter the carb throat is on a 1bbl carb, but I would have thought it is smaller than the 2bbl and 4bbl throats. If so, you will need an adapter to fit the air cleaner to the carb.

 

i am putting a offenhauser intake with the edelbrock 4bbl carb on her

 

I missed that. Given that, the air cleaner will fit. BUT, you may need to put the 2nd snorkel on at a place that will clear other things under the hood. So, I would consider starting with a single-snorkel air cleaner and modify it. Take two air cleaners and meld them. Put the cleaner on with the existing snorkel pointing where it should be to work with the stock ducting, and then see where the 2nd snorkel should be.

 

yeah i was thinking that also. i remember seeing an episode on powernation of them converting a olds single into a dual. i was planning on an idea if i got the mustang one i could run both air intake hoses into an open area of the inner fenders similar to how dodge did with my 99 ram that i own.

 

The inner fenders would be getting dirty air from behind the tire - right?

 

True but all the ones that I have seen go into the fender well is to the front side.
I also don't think it is in the open wheel area but a void between inner fender skin and wheel well were the air would be cleaner.


If you cant duct it forward to the grille area how about under the front bumper to pick up cooler air?


Now I have to ask has any one done a test on air flow CFM of a filter assy. with just 1 snorkel? How much CFM do you think your air pump (motor) can pump? What do the modern Hi Po cars use for filter openings?


My take un-less fill on race and even then there is no need for 2 snorkels on the filter assy. other than WOW!
