I want to cut a hole in my hood and put a functional scoop in kinda like this one but the filter will stick up just a little bit higher.. will there be a problem with rain getting in there? or can i fashon up a deflector sort of thing that will deflect the water but still allow good air flow into the carb?

Unless you are driving in a real hard rain, it should not be a problem. I have one on mine with an air filter mounted in an air cleaner unit that is sealed around the scoop.. I get only cold air to the carb. Any water I get in from a rain actually will drain ont the drain holes in the rear although, in Az., I have yet to find rain to drive in. A little water will burn on thru the engine.
 
What i did was intsall an original air filter housing with no lid and I lifted it with spacers untill it was really close to the hood. Then i took some weather stripping and sealed it to the bottom of my hood to keep heat out. You will need to block off the inlet tube hole if you really want to keep out the heat though. I did not notice a difference in performance but it was a neat project to do myself. Just thought i would let you know some more options
 
i have a similar set-up to bleedfordblue65 but i will be using a stock (or close to it) 68 1/2 CJ mustang or ram air 68-70 cougar type seal with the air cleaner base at stock height although the lid sits a little higher because i'm using a taller filter. i've been running mine for several years without a seal and have driven in rain a bunch and haven't had a problem yet. i would not use the K&N X-stream filter lid like the one you posted though, i'd be worried about water with that set-up but a steel air cleaner lid is fine.

I have a similar setup (se garage) but using an oval K&N filter thru a 66 Shelby scoop. The filter base is level with the hood and sealed with weatherstripping on the cut out edge of the hood. We get rain here quite often so I have a wad of K&N filter foam stuffed into the front of the scoop to break up drops. The engine runs fine with some "water injection". :rolleyes:
 
The only potential problem would be with using a paper-filter. You don't want those getting too soggy since they will plug up and not flow well. The K&N should have a film of oil on it so it wont absorb water like the old paper ones did.

I would not worry about getting water into the engine at all.
 
I'm using the original base with the snorkel blocked off and drain holes drilled with a 14" air cleaner. No problems what-so-ever. The original base clears the fuel inlet on the edelbrock carb without the need of one of those crappy plastic spacers.

What little water will probably increase performance. hehe. Between the filter and carb the water will probably get turned into vapor pretty quickly. It's not like you have one of those 5.0 ram airs that have a scoup under the front passenger side bumper which sucks up puddles. If your filter lid gets waterlogged, your engine will probably end up drawing air from the round aircleaner anyways because of less air resistance anyways. Ram airs that face forward really don't capture/force a lot of air because the middle of the hood is a low pressure area. If it was facing backwards(cowl induction) or the scoup was at the nose of the hood like the 68 Shelby it would probably be more apparent.
