Where would you plan to put vents that length?

Remember, it's a rather shallow area between the rad and the front of the spare tire compartment.

I can't comment on the Mustang vents, but from the layout, there isn't going to be much airflow through the radiator with it at that angle. The air will be like a rock skipping across a pond. Without airflow through the rad it will become a heat sink rather than a heat exchanger. Personally, I think you'd be better off with a wider, less tall radiator that's more upright, but if you're determined to keep the current layout, then putting a shroud in front of the radiator to redirect the air upwards and through it rather than allowing it to escape around the sides of it would be a big help.

Yeah that's a very old picture. I just didn't have any that are recent of the radiator there is a big air damn now in place that funnels air up threw the radiator while the car is in motion . I have a big hole cut out of the hood so the moving air can escape from under the hood. I was connaught cover the hood with a cowl but thought that these might look pretty cool instead an still relive under hood pressure and hot air

This. That looks like someone didn't understand the Fiero cooling system or air flow, when building it. The only way I see that being able to keep the car cool is by sheer luck of the fact that it is so huge and has two full Fiero shrouds and fans sitting on top of it. But even cruising on the highway, it looks like the fans would need to be running constantly to keep the temperature regulated, due to the huge disturbance in air flow created under the front of the car.

Is the engine running ridiculous compression, or running a bit lean? I don't see why a normal Champion 3-core radiator designed to fit in the stock Fiero radiator location, couldn't keep a 454 cool, especially if it's running ~9:1 compression and the right air/fuel mixture. If it can keep a supercharged LS7 running at the right temps, it can work for a big block.

I sell these if you're interested:

http://www.embraceracing.co...ecvent.php?e=0,3,9#0

It's a decent surface area. If you wanted two they might look pretty cool one behind the other. I could give you a deal on a pair

No I have absolutly no cooling issues . I run a 165 thermostat and on a hot summer day never get warmer then 190 200 max. I have a air shroud that I made out of fiberglass that redirects the air threw the radiator . Before I had cut the hole in the hood the Temps were considerably higher . I use to just leave the hood un latched so the air would flow threw an out but I had the hood pop up one time an stay latched on me while I was drag racing someone so I cut a hole in it. The cooling system works very well now. There were issues at first yes but they have now all been worked out the system is rather massive . But very functionable.

There's also the Lumina Z34 hood vents: http://www.fiero.nl/forum/A...050818-1-051266.html

And plenty of people have done the Sunbird Turbo hood vents on the Fiero, as they fit nicely in the forward section of the hood between the headlights.

Wouldn't directing the air flow up create undesired lift? Hood vents help address this, and I guess it's better than the factory drag of an upright radiator.

I saw a Fiero with the ”radiators” in the back, behind side scoops. Only a small block V8 engine, but it seemed to cool OK.

Pressure build-up under the hood creates lift, yes. Hood vents, and vents into the wheel well help address this. Remember, the factory radiator installation isn't quite vertical. Drag is created by turbulence more than pressure. Removing the entire front bucket to install horizontal radiators does create more drag. Hood vents also help with this. Radiators in general create extra drag, when it isn't necessary to have air flowing through them.

Several Lambo replicas have radiators in the rear, particularly the tube chassis kits, with the BMW V12. If it takes such a huge radiator to keep a carbed 454 cool, then something is wrong with the cooling system. But whatever works and makes one happy, I guess.

I can say that there is a serious lift at like 130 mph before i cut a hole in the hood. now its a lot better . as for the size of the radiator . i believe in better safe then sorry . why have what will just cover your needs when you can go above an beyond an make sure that nothing ever goes wrong. once all the air pressure was bleed out of the system this cooling system has been a champ . if you think the radiators too big you should see the cooling tubes LOL. But on a positive note I just got off the phone with V8 Archie im now getting a Hatchback made . Im Soooooooooo over joyed. an i think i changed my mind on the vents im gonna do 4 firebird fender vents

A 2 row champion radiator for a 4 cyl auto Fiero kept my 383 stroker cool very well with a 160* stat too. Never ever got hot. It did not have a/c.
