dose any one know
 

if there is a cold air kit made for a carb. 5.0. i have a 85 and i would like to put one on it. dose any co. make one?

IF your not talking about just getting a high flow filter setup like the regular round K&N filter deals. There is a company that sells kits to make your own CAi for carbed motors. They are ugly and add unneeded weight but they make them.

so should i just get a k&n filter, stay with the sock cover or go with an open one?

Its carbed so you just get the standard 14" round filter like this one:

And then get a 14" top and bottom plate like these ones from summitracing.com
This one is a combo with highflow filter top and bottom plate all for a great price. Or you can look at other ones like they have ford racing ones too.
