you are likely blazing a trail with this one. one way to find out basically. me? cut some cardboard up and hot glue tack it to the vents. then coat the cardboard in glass resin. then cut away from the vents at the hot glue tack points and now you have your vent contour that you can now kinda set on the hood and see if its close enough for government work and worth your time hacking up your hood.

 

make sure you have the wind deflector under the core support. It seems like a stupid little piece of plastic but it plays an important part in cooling.

 

Oh yeah that little deflectors down there making jacking a pain! haha

Good idea with the cardboard/resin there, that's a good starting point.

 

it is such a STUPID little pos, it has to be a big part right? I have known more than a few people that had temp issues while rolling after they tore it off thinking it was lighter/faster....

 

Yeah mine didn't have it when I got it, i didn't know for the longest time it was missing anything.

 

I think you're going to need more vent than those offer. On my '86 vert, I also run a 347, big 2-core aluminum rad with electric fans. I put a big vent on the hood which does work but not as well as I'd hoped. Looks good though.

 

I'm running the lmr 3 core and a mark vii fan. Underhood temps get pretty brutal here in the summer here still.
That is a sweet looking vent! Was it a universal one or is it a fox specific one?
I was also looking at getting a set of race louver ones if this didn't work out. But if anyone knows of an effective universal one I wouldn't be opposed. I was cooking up this idea because I really like the mesh to guard the engine bay from debris but I suppose I could add that to anything

My rad uses 1.5" cores, and the fans are dual contour, The vent is a universal I found on e-bay - they had several designs. The one I selected had the dimension and slight wedge that fit the Fox hood. When stopped and the fans on, you can feel the heat being driven out. But on the move, I'm not sure - never tested it with tufts of yarn.

 

Heck that's all I need is that air to not be stagnant under hood when we're parked and waiting. If I could get a little help while driving it couldn't hurt. I originally thought of these vents thinking putting them over the headers could help a ton

 

Interested to see how this looks...

 

Update for everyone we had big storm up here so the junkyard we were going to pull off of was mudded out. So next weekend we're going to go get the template/contour made up

 

I have gotten the vents in, and we're pretty sure they will fit about here.

they will go here without cutting any supports .Been raining like a sob so haven't been able to do much outside work. Just wanted to show you all a visual update and get any thoughts on a potential better location.

 

I think they will look good. But, given my experiance with the hood vent I have, I'm concerned that they will not provide the flow you'er seeking. This is because of the underhood flow around the inner fenders and other engine accessories.

 

You may be right, I'm hoping it'll be enough to help the air escape. If I'm not satisfied I'm not opposed to adding a vent similar to yours to help airflow. I'm gonna get this all figured out before we paint so I'm not chopping up a fresh paint job. I'm also looking at making a set of those rte looking intake turn signal lamps to help more air come in and because I like how they look. Found a busted set of lens housings at the scrap yard while I was there so I don't feel so bad chopping up old OEM parts
