Go ahead and do it , i would like to see what you come up with , im allways interested in air intake systems , i don't no if it will do much on a stock truck that dosn't turn much RPM , mustangs are another story , when you modify a motor with good heads , cam , and exhaust , then its time to start upgrading the air intake sysem , which usally will include a mass air meter , MA meters are very sencitive to air flow , so the meter needs a different tune for cold air intakes most of the time , any bends in the intake system will change air flow , so different air systems will need a different calabration on the air meter , or a custom tune , the tune being much better . Cold air intakes don't help much , after the truck reaches cruising speed the air moving though the grill makes the air intake temp about the same , this has been tested many times , so you don't need alot of special stuff , a good conical filter with lots of intake area will work fine , but on a stock truck a good flowing drop in filter will be fine..JMO...Lew

Musta been a full moon, from looking at the posts that came up in this thread last nite!

Anyways, all kidding a joking around aside, look at this pic and think for a couple minutes



The intake, air tube, air box design is not conducive to building a ram-air setup... your best bet for making a functional ram air is either try and find the aftermarket hood that had the 68 Shelby GT500 style scoops up on the front of the hood (I've seen em, but d@mn if I can find the website now) and modify a camaro air box to run the hoses over to the intake.





Otherwise, most anything that is done to try and run ram-air from the hood, to the airbox, and then to the intake is going to not only end up being a cobbed together mess, but will most likely not help and very well may hurt performance.

The other way to get to a functional ram-air would be to swap to a carb and do something like this

(These are pics of Sportruk's F series)










Also, in 23 years of customizing things, I have come to one BIG conclusion, the majority of the time (with exceptions like Sportruk's above) that I see someone take the "I did it ALL myself" route, the end result is usually not that good. Fit, form, function, performance, and safety are all usually lacking. This is not always the case, but more times than not, I have spent time undoing other problems caused by people who grabbed a six-pack, some torch's and some vise grips and tried to make something from scratch.

Damm i miss the holleydays LOL , back then they had some nice ram air set ups , had a 71 TA 455 HO ram air IV with the scoop on the air cleaner with the hole in the hood , had to rebend the stock air cleaner to get a double pump holley to fit under it , then modified the top of the air filter top to bring more air in , with another filter over it , simalar to the K&N filter tops they have to day , ..i really liked the 60s & 70s....Lew

Looking at some of these pictures, I think there is some confusion between ram air and cold air intakes. Either way, with a real ram air system, unless you have a laptop and the software for datalogging while driving at different speeds, you're not going to be able to tune it properly.

Like I said, I don't think you have a computer controlled tranny, and I am pretty sure your speed density....so if you really want the scoop style ram air like I said you could ditch all of the EFI, throw on an Edelbrock Air Gap intake, Street Avenger Carb, and then fabricate the induction to the hood scoop. IMO that would be about the only way to do a hood scoop ram air. Now if you are just looking for Ram Air, I have RAM Air Box for a carb, happens to be for sale...along with a Moroso Low Profile aluminum Air Cleaner and K&N 14" filter. You can check out the details at ramairbox.com. Only thing is you have to decide where to ram the air from, grille, etc. I had this on my '73 before I pulled the motor to go in my '95. I have pics somewhere on this site of the setup when I first put it on...

Agreed... The pics of hood scoops are nothing more than cold air intakes. To get any ram effect the whole intake tract has to be designed(shaped) to produce positive air pressure at the throttle valve, and to get any significant amount of air pressure vehicle speeds have to be well in excess of the legal limit, so these systems are primarally for looks.

...Im not sure what it takes to be true ram air , but the pontiacs said it did , 400 ram air III heads , 455 HO ram air IV heads & the 455 SD ram air V heads , the 455 HO TA would run 135 MPH at about 5800 rpm with 3.42 gears with a T-400 M-40 trans , would that be enough ? i don't know if you have ever driven one but at that speed the car is very stable , starting around 100 mph the spoilers start doing there job , i think it lowers the car about an inch from the down force...

That's pure marketing BS. There have been a few vehicles made with a true ram air intake system but none of them came on 4 wheels.
