57 Fresh Air Ducks.

[acardon]

I have eleminated the fresh air ducts between the inner fenders and firewall and welded the firewall holes shut. Now, what to do with the holes above the headlights? Would there be any advantage to putting the vent in, open to the engine compartment? (I don't intend to have any cold air vents to the throttle body (350 ramjet).) Would this create a back pressure in the engine compartment and prevent some air from going through the radiator?

What about the "fowl" air "ducks"?

Don, I don't see any harm at all in leaving those vents open. It might help keep the engine compartment a little cooler. Are you planning on just having your RJ pull warm air in? If you're not interested in max performance, that's probably fine. But it will help of you pull cold air into the TB.

We have a lot of geese this time of year here as well as fresh air ducks.

I'd recommend a cold air duct to the tb from one side. Free hp (kind of).

As far as your exact question, think about the relative area of the grille vs. the headlight grilles. Not much comparison. Leave them open if you don't do a cold air intake to the engine.

I only installed both front ducts in hopes of using them someday to feed the intake. But they have to be installed onto the inners and then the fenders before you install the fenders(found out the hard way). Good day, Henry.

I used the front part of the front duct, I cut about 5" long, because you need some of it to mount your headlight bucket

That just quacks me up.......

Thanks, guys. I just wanted to get my ducks in a row. I'm not really interested in getting max. power, just a street driver, so no cold air inlets to the TB. After all, I bought a Corvair new and still drive it almost daily.
There's not a lot of air can get in those grills above the headlights, is there?
Cutting them off behind the headlight may be something to think about. It would give more room to run the A/C, heater hoses and wiring, under the fender. The drier is going in the wheelwell also.
Of course, the ducts on a 57 do protect the fender eye brows from rusting out from all the mud and water that my car will never see.

I think you'll be good either way. It's not like you sealing off the front of the radiator. You could use them as people suggested or you can cut them off for more room like you are thinking about.. Either way, I think this is a matter of preference.

Route new lines from the back of those and point them towards your disk brake caliper...NASCAR style. :eek:
