This one looks good. A big filter is only going to help to a point. From a logical standpoint which seems better?

A huge air filter that flows 10,000CFM but draws from a hot engine bay?
or
A cold air system that flows even just the same as the carb CFM rating but comes from a cooler source?

These are 2 basic rules:
-Engines are air pumps and can only move as much air as the greatest restriction.
-Cold air makes more power than hot.
 
driven - Okay, so you make 2 hp what gives?

The only thing flowing a certain cfm is the carb, not the air cleaner. Flow isn't the point, it's restriction.

You're gaining as much using a high pressure area of air, but restrictive CAI as you would with a less restrictive air cleaner. You put that less restrictive air cleaner in a setup with a shaker/ram induction or cowl induction, and there's not any CAI setup that can perform better on a carburetor. The point is high pressure air and less restriction. Both = better.
 
I can understand both sides of the arguement on this one. It's really up to what the owner wants. I went with the Cold air intake because I live in south texas and its always warm here except for two months out of the year. Having a set up like custom442 would be forcing a lot of hot air into the piston chamber for me. Now if your up north where you have some decent temps for some parts of the year, then his set up would be good in that sense.

My thinking with this set up was the air flow going through the tubes would cool down by the time it reached the carb. It helped with my gas mileage for sure which is why I'm getting 18-20 mpg. The styling I was going with for my car was a new old school look. I thought this system captured the old muscle car look while looking like a newer style. I also bought one of the classic stickers that are on the 60's chevy that say "350 turbo fire" to add that extra nostalgia. I added the cowl, as suggested by custom442, because it helps release hot air from under the hood even though I have a CAI.

My 2 cents, I wouldnt have anything sticking through my hood unless it was an 8:71 blower. Either way, its up to the owner and their preferences.

a lot of good points here, I really think it's personal taste. And that hood's not stayin on there guys, it's just temporary until I can afford a new 500$ cowl hood. At that point I'll rig up some way to make the cowl functional and keep the engine air outta the intake air.

It shouldn't be too hard to make the bolt on one from vfn functional, see how it's made underneath to where you could drill and bolt on the front/back braces:

Anything is better than stock, but like I said earlier I just can't see how a closed up box with a restricted air cleaner and tubing could be better than a high flowing air cleaner and a whole cowl or hood scoop (no disrespect to patmckinney racing, it does look nice and prob works well too)

personally i really want to do what custom442 has with this scoop:

wait till next week, I'll post in one of the old threads on how I made a cheap hood scoop for it, I keep putting it off along with the header panel but I'm gunna have to finish it sometime. It's similar to the one you might buy
 
If it were me, I wouldn't just because I never have been a big fan of those square scoops. They really take away from the styling of your cutlass, and rather than keep the few curves that our g bodies have, it would would make your cutlass look like a loaf of bread or box. But again it's up to you.

Now if your gonna go ahead with having an air cleaner through the hood, I personally like the finned hilborn air scoop that has the open mesh front. Don't use the triple butterfly flap or double barrel shotgun style if you don't have a tunnel ram or blower cause it looks ridiculous. Then when you cut the hole in the hood make sure you work the hood around the edges of the hole and make it look like it was tailored or stamped that way from the factory. You can used body filler, door edge molding, or another type of trim. I'm sure someone out there is making some or has come up with a good product for that.
 
if i go with the hilborn scoop. id face it backwards. kind of like the trans am shaker scoop. so if i drive in the rain it wont be such a big deal. kind of like this:

I think it'd look cool, but that's not a high pressure area so the performance gain would be nill. It'd suck air just fine though much like a stock air cleaner

Try one of these: front of car (bumper area), forward facing scoop over 1" above the hood, and of course there's induction at the cowl
 
umm what if i make a tunnel going from the cowl to the scoop. this way i get the looks and the functionaslity of it?

of course the tunnel will be under the hood so it wont look wierd.

I think that'll work vlad, if you can make it work. It'd be something different too. See if you could make some sort of catch under your hood to direct water away or seal it with some weatherstripping so the rain won't be pouring on the intake if you get caught in a downpour
