Has anybody installed the Track Spec Louvers on their standard hood? I want to get rid of some of the heat in my engine bay and found this heat extractor on Summit Racing. It measures 15.5 by 15.5 and extrudes downward towards engine 7/8"
I have it on my L-88 Hood. And it is 1/4 inch away from hitting the air cleaner. Unless you have a High rise hood, I don't think it would work.
I would put some clay or foam on the air cleaner and close the hood to see how much clearance you have first. Then go from there.

Did you position it way down in the front or near upper back? I am guessing this vent works well?
Sorry for the dust. lol.
I put it more up front to help with lift at higher speeds. The L88 hood has an opening toward the windshield with the high rise hood. Plus I think it looks better more up front.
They also have a smaller version at Overall Length (in.):
10.60 in. Overall Width (in.):
15.50 in.
I don't think the smaller version would look as good.
Any vent will help with heat issues. I haven't pushed mine to see how much of a difference it makes yet. Just put it on over the winter.

Another way to check for clearances is to wad up some aluminum foil to see how much it compresses.
Not my idea but saw it on a car show on TV and thought I would add the info as another option. .
The real question here should be, after more than 40 years. Suddenly there is a issue with heat under the hood? How did the car get by for the last 44 years?
Perhaps you like the look of the louvres ?
I found that removing the tar paper-like material covering the A arms made quite a bit of difference in my 81, allowing hot engine air to escape through the gills as originally intended.

Always was an issue
1968 Road & Track review.....Let's get down to the test cars at hand. The first car we borrowed from Chevrolet Division was the growling 435-bhp 427 model. From the beginning it was a problem: it seems the stylists didn't provide for adequate flow of air through the engine compartment, and even though the local people had installed a great windmill of a fan it had a marked tendency to overheat both itself and the passengers.

I installed a mild camshaft and some headers, so heat is an issue. It gets worse when I turn on A/C.
I have electric fans and have made an airfoil to divert air from going to the bottom and go to the top instead.. This helps a little, but if it had a way to get air to go free on the top. Imagine the possibilities.
What about water issues...like when you wash it or drive it in the rain?
Good question, I believe I will just wash it very carefully. I think my car engine would be happier running cooler than getting a little wet every now and then. Who knows, maybe my a/c might even cool better.

Hope this helps.
It looks pretty awesome. That makes your car look meaner looking. It kind of says don't mess with me, I have power under this hood.
I didn't want to cut up my custom painted hood. So I bought the 1981 twin turbo hood with vented cowl induction. Sitting at a stoplight I can see heat waves coming out. It helps flow through the radiator because the vents are back in the lower pressure area.
I put a vented high rise hood on my car waaaayyy back when. When I first started to raise the power in my car. So perhaps I don't realise the issues guys have with the stock hood.
I just know how many times people post on here. "Will this fit under my stock hood".
And everytime I think, just F off that stock hood!

I put C2 big block vents in my hood. There wasn't much room with the cold air induction. I can see and feel the heat coming out. I put the right above the headers. Wish I could have squeezed bigger vents in but the engine stays cool with the giant dewitts radiator and twin seal fans.
For some reason CF won't upload pics, I'll try again later
I have a Baldwin motion hood open in the front and the cowl. It really moves the air through and with the 5 inch high air filter the carb gets cool air. .

Who knows, maybe my a/c might even cool better.
