I decide to make a cold air for my 1979 with a 383 SuperRam . I mocked it up with florist foam. After shaping it I covered it with 4 layers of fiberglass. Ive just gave a thin coat of body filler. Then Ill remove the foam and clean up the inside. The plan is to finish it with carbonfiber hydrographics. Ill find some type of seal, maybe C4 front wheelwell weatherstriping?

I like it! I have an LT1 and plan on doing something similar. Might try and put an scoop in the front of the hood to feed it some fresh air. From the looks of that mesh in the picture, it kinda looks like you have one.

Any more pictures of that engine?

Looks like a nice job!

The ducts in the hood wont be able to feed cold air into the cleaner because they are right above the A/C compressor and the alternater. There just isnt any room. it should benifit from positive pressure from ahead of the radiater. The core support is sealed pretty good so im hoping it works out,,,

Ok. It looks like you have a twin turbo hood. I found this a while ago, and think it would work great for a forward facing throttle body.

I like a unique engine, and I can't say I've seen a Superram in a C3 before.

Pain to assemble but man do they make huge torque even on a 406

I make up new swear words when I have to assemble it,,,lol. Even locktite doesnt keep all the bolts tight.

Is this how you have been spending your time? I never got a response for my last message for a beer!! I guess I will have to bring a six-pack to your house and just supervise your project. LOL

Pretty cool idea using the florist foam , make sure to post pics of the finished product!

QUESTION: How good do you guys think the factory cold air induction system is onthe '81?

I was thinking of using the front two pieces of the factory system, then replacing the acordian tubes that went to the air cleaner w/ smooth either plastic or insulated sheet metal and making an air cleaner. Have prints f/ a very good air induction air cleaner that will receive the smooth tubes straight on.

I had a different approach to cold air intake on my '79. I decided to go with cowl induction. Of course, you have to be willing to cut a hole in your cowl. I was, since I can always fill it if I ever wanted to change it back(I don't think so!). It fits perfectly under the stock hood and works fantastic - all for $165 total! I have solid motor mounts, so engine torque isn't a problem. I have an Edelbrock 800 carb and Performer RPM manifold. I used Spectre parts - all polished aluminum 4 inch system - capable of at least 900 cfm flow. Parts: #9849 4" plenum, #9604 4" velocity stack, #9709 4" x 4" tube, #9749 4" 45 degree elbow, #9776 4" couplers(3), #4208 low profile air cleaner nut. A real increase in acceleration vs. my previous Edelbrock foam carb-top filter. I was shocked, I had no idea it would work as well as it does, especially when the engine gets warm! I have pictures, and will post them if I figure out how. I recommend this upgrade to anyone that can afford it.

That sound interesting. Look forward to the pics.

Here are more pics of my cold air intake system. First I'll show my old underhood Edelbrock filter:

And now the newly placed Cold Air Intake w/ Velocity Stack in the Cowl. True Cowl Induction!

Close-up of the Velocity Stack in the Cowl(cut 1/2" off of bottom of velocity stack for clearance):

As long as you have solid motor mounts, this system will clear the stock hood. All the parts are Spectre Performance stuff, and the whole thing costs less than $170!
I guarantee you will feel a very noticeable increase in power and acceleration - I sure did!
Also, it doesn't cover up half of your engine, like some of the over-the-radiator systems. And you really don't get cold air from the top of your radiator. That area runs nearly as hot as the rest of the engine compartment.

Where's the filter? Is there a cone filter inside the tubing?

And what's the significance of the solid motor mounts? Does it let the engine sit lower?

I was able to clean out the foam today and found a couple thin spot that need re-enforcing. It looks like it should be pretty sturdy. Now I need to figure out how to clean the foam out so I can add some glass.

I have a screen filter between the velocity stack and straight tube, where the blue silicone connector is. That's all I want for my application, as I only drive paved roads, and am not concerned with dust. You could put a foam filter somewhere in the system if you wanted though.
The solid motor mounts keep the plenum(on top of the carburetor) from hitting the hood during acceleration when torque twists the engine. I had the solid mounts in place long before I decided to put this system in my car, but since clearance is limited between the hood and plenum, I would have added them if I needed to. I measured with clay on the plenum when I slowly closed my hood, and found I had about 1/4" clearance. I cut away some of the hood blanket where the plenum and pipes run, since it was squishing against the parts. It doesn't look bad though, in fact most people don't even notice it's cut. And it doesn't droop because there are retainer clips all around where it needs to be cut.

I like it !!

Acetone should take care of your remaining foam issue.

Finally found time to finish air box. Looks better in photos, will clean it up over the winter. Might have it wrapped in Hydrographics like carbon fiber
