I'd like to see some pics from those who have functional hood scoops, single or dual, on their truck. Also, if anyone has a cowl induction hood sealed to force the air intake from the cowl area, I'd like to see that as well.
-
I'd like to see it too.............
-
ehh give me a year or so and i'll post pics in this thread...:D

Thanks, do you have plans to seal the air intake to the hood? I'm a big fan of cold air induction, but don't like how restrictive the factory arrangement is. I'm leaning toward getting a cowl hood and fabricating a box that will seal the air filter assembly to the hood, to force it to use air from the cowl instead of the engine bay. A ram air hood would be nice, except it would allow so much water in the engine.

they sell a top that go's on top of the carb and it looks like a cold air set up its about 60$ but than you got to buy a pipeing and filters and im not tryn to spend 80 or so on more k and n filters haha but it looks clean right now im working on painting my driverside after getting hit but that looks like its next .. ill run across the article agine and ill post it!
-
Sweet, thanks.
-
Wow. That's a beautiful 75.
Wereworf, did you ever thinh of a dual snorkle setup? http://performanceolds307.tripod.com/id3.html
-
Yeah, I had one that looked almost factory on my '84, but a 4"x14" open element filter offered a more noticeable improvement in performance.
-
My first 1976 Scottsdale had a factory corvette dual snorkel breather with the hoses and pods installed in the core support... man was it sweet, especially once I cut the bug guards off of the core support mounts. BTW, unless you want to buy A LOT of air filters/ K N Filter Recharger kits, leave the bug guards on.
-
i will be doing a functional cowl in the spring, once i get the steel hood ill be doing some fab work to make it work ;D, only thing im skeptical about is sealing it without extream wind noise
-
I've moved to the idea of using a ramair box setup, with bug guards.
Heres the company's website http://www.ramairbox.com/ (http://www.ramairbox.com/)
And some pics from 73-87.com of an install for our trucks http://www.73-87.com/7387garage/drivetrain/ram_air.htm (http://www.73-87.com/7387garage/drivetrain/ram_air.htm)
It utilizes a 14"x4" round air filter instead of the relatively small factory filter.
Though I'd still love to see anything anyone does to seal the intake to the hood.
-
Well this is my 1986 With a real hood scoop....Take the Red plug out and it goes to the carb

Nice looking truck, I really like the "practical" look, especially on a 4wd. ;) Do you have a way of sealing the air cleaner to the scoop, or do you just have it blowing air in around where the filter is? Or are you running w/o a filter? :o
-
Um no i use a Round k&N panel filter..and On top of that is a fiber glass Shroud...That Bolts under the hood scoop so when the plug is out and its not raining ..The air that is "filterd" goes into the carb...i love it to me its the best thing i could of done..and it gets alot of looks
-
Do you have any pics of the under hood parts? I think I can visualize what you're saying, but it would be nice to see.
-
No pics...But ill get some...I got the idea frome Horsepower Tv...It was a drag car anyways...And i made the fiber glass shroud my self with fiber glass and i made the mold out of foam...I think it all cost me 100$ 40 for the hood scoop 10 for bolts and washers and paint and the fiber glass and foam Sure beats the 500$ for a cowl...More bang for your buck
-
Did you fabricate a seal for the cowl induction hood yet?
-
I have seen more proven power with the ram air/ snorkel type setup Most core suipports on these trucks have another hole in the core support filled in with a dummy plug. I have removed the plug, added another norkel tube to my existing air cleaner, and the bug gaurd from the right side of a donor core support, and if done right, It actually looks factory. A big problem around here is young kids doing inspections and dumb rules about having the factory snorkel and heat riser tube in place, or no inspection. I can't get my wifes 81 inspected because the factory air cleaner will not fit the new 540hp 468 and clear the hood. I guess it's time for classic taggs that don't require inspections, but limit it to other than daily driving. The open element sounds more impressive, but the hot air ingestion kills the performance.quarter mile ET's prove that theory. I know race cars have open elements, but the don't run enough to get as hot as street vehicles.

Choptop, Something like this?

Yeah I've decided to go with a "ram air box" setup when I swap motors, since it utilizes a 14x4 element and dual snorkels..I've already got a spare 4" factory bug guard from my '84 that will go on the drivers side in that cutout. I currently use a 14x3 chrome air cleaner. Inspection stations here don't even open the hood. Doing it this way also saves me the expense of a cowl hood, and it'll also let my truck keep a lower profile to be less of a target for would be thieves and vandals. The Predator 10k thats going on a fender mount is going to make it stick out bad enough..
-
That is exactly what I am talking about. Love the OLDS. beautiful setup. was this originally a diesel setup
-
Choptop, No, it was originally a 4.3 V6. This is my second Olds powered pickup. The other one is a '78 4x4 longbed. Thanks for the complement, Lorne
-
hahah, that OLDS emblem in the grille is AWESOME!
-
I asked because the olds swap was common in the first diesel trucks, but after I posted I realized this was post 5.7 deisel. Had a friend with a 426 out of an olds toranado in his,and it was awesome. The dual snorkel setup will not only disguse your truck from theives,but also make it more of a sleeper. I can;t remeber the exact trucks, b ut many had a tall air cleaner( which is either a 3 or 4 " element, I never measured it) is perfect to modify to a dual snorkel, and will accept a k/n with no probs. should be able to get one in a junk yard cheap unless you already have one
