1967 fresh air intake question

[Teal68]

I'm building a 67 Bronco I have into a half cab, and trying to use as many of my parts I have laying around from all the Broncos over the years. I'm using a later model, not sure what year, air cleaner and air cleaner snorkel. I also have a fresh air intake tube in great condition that I'd like to use. To be specific, the plastic rectangular tube that goes along the inner fender on the passenger side. I don't see an advantage because I do not see an opening in the core support. Did 67's not come with a fresh intake of any sort?

I don't mind cutting a hole if I insist on using it. This just has me wondering what the deal was in 67.

Thanks!

No the 67 didn't come with a fresh air vent, the snorkel pulled air from the engine compartment.

I cut the hole in the Rad support to fit one of those tubes on Clifford and on a previous Bronco build, a fresh air supply to the EFI filter. You can just barely see it in the first picture.

Fresh cooler air means more HP and if you can directly hook to the tube with a later version Air cleaner assembly, why not...

My 73 has a fresh air intake. But I don"t think it's stock.

Interesting. No hole like that on my '69 either. When did they add that?

73. . .ish

Correct. It was a 73 item.
The actual holes in the core support, along with the little bump-out for power steering, started appearing in the core supports of very late 72 models. But the snorkels and power steering only came on 73 models.
With just a very few making it to extremely late 72 models.

All good stuff guys! Thanks for the info. Since I have all the pieces I'm going to open the core same as 904 suggested.

I'll have to relocate the regulator, but that's no big deal since I'm doing wiring, too.

Some people put the regulator on the wheel well facing the battery, but that’s still a little awkward. And since you’re re-doing the wiring anyway, 73 and later models usually have it on the firewall just behind the wheel well.
You could also put it further back along the fender skirt/apron. Basically several inches behind where it is now.
Or if you’re updating things anyway, you may want to upgrade the alternator to a more modern internally regulated one. Which eliminates the external regulator altogether.
Now would be as good a time as any.

I'm definitely considering that. Thanks for the added info.

If you're not doing a true restoration then I'd just do it.

And, pre digital pics age, so no pics, but I built a ram-air intake system for the '67 Ranchero that I owned in the 90's. Moved the battery slightly, which exposed the battery vent holes in the core. Built a piece that was screwed to the core support that transitioned from the roughly rectangular shape of the vent holes to a Ø4.0" It had a "bleed" tube in it that blew some air across the top of the battery. Added a plenum with a Ø4.0" inlet tube to the air filter assembly and ran some simple plastic ducting between them. Used the flat sections from a bent (as most are) Square Body Chevy truck hood for the sheet metal to make all of that.
