The RPO is P28
Look at the thread” Identifying a 68 L78 Camaro?” I think it’s called. The option on the window sticker says Spec 15” wheel & Tire. It’s a big revelation as a previous unheard of option on a non Z/28 Camaro.

So what would you call this car?

I would call it a beautiful car.

Sure looks like a 67 Z/28.

Not sure what that flat hood has to do with the "ducted hood" "cowl induction hood", "super scoop" hood discussion. If the pictured 67 has air coming through the cowl vent, then it is from a cowl plenum intake set up. Has nothing to do with the hood.

I was curious because he didn't think it was proper to call a car with a cowl plenum "cowl induction" since the term may not have been marketed till 1970, but the Z/28 didn't truly fall into its own until the middle of the 1968 model year, no? So what would a '67 with package Z28 be called?

1967 Camaro Coupe with RPO Z28BA or 1967 RS Camaro Coupe with RPO Z28BA. With Air Plenum: RPO Z28BB. With Headers: RPO Z28BC. With Air Plenum and Headers: RPO Z28BD.

In 1967 Chevrolet made two body style Camaros and 4 models: Plain, RS, SS and RS/SS. There are no emblems on a 1967 and partial 1968 saying Z/28. Just the stripes. You know all this Diego.

As you said, the moniker didn't appear until they changed the front fender emblems from "302" to "Z/28" and added the Z/28 emblem to the rear panel in 1968 published this ad. That's when it became an additional model: Z/28, which joined the other 4 models.

It's the need/desire by many (especially here) to add monikers to performance cars. It's a 1967 L88 Corvette as opposed to a 1967 Corvette with RPO L88. Or a Tri-Power GTO. Or . . . A COPO Camaro/Chevelle. Option/option packages that weren't visible/emblemed (like 1969 - 1972 W30 442s).

They all were optional packages, not models. But they all changed the identity of the Camaro so, like the Judge package for the GTO, we kinda see them as models. I think the Z/28 fits that role well.

But my question was pertaining to retroactively applying a name to a similar car. If he's not keen on calling a '67-68 with a cowl plenum "cowl induction" (I guess with a little c and I), would a Camaro with the Z28 package be approached in the same manner?

Up until 1970 Chevrolet never used the moniker "Cowl Induction." The Air Plenum first appeared on the 1963 Z11 Impala. Borrowed from Chevy's NASCAR and designed by Smokey Yunick.

All you're trying to do is retro-fit a moniker Chevy used in 1970 to an option on a 1967/1968 Camaro. Cowl induction describes what it does but it was called "Air Plenum." Don't move the goalposts.

I'm not trying to do anything but ask questions and learn.

So would you suggest if it's not correct to call a pre-1970 car with an air induction system "Cowl Induction," would you also say it's not correct to call that green '67 I posted a Z/28?

It's all semantics. Doesn't bother me what anyone wants to call it.

To me Chevrolet just confuses the issue calling it a special ducted hood and the very next year called it cowl induction on the Chevelle.

Thinking of it in a literal sense a special ducted hood could apply to just about any style hood that grabs fresh air, from any place. They were all special for all models. At least calling it Cowl Induction or Cowl Plenum tells you "where" it's grabbing fresh air. With that said it seems to make the most sense, whether it's grabbing it through the rear facing scoop, or through a hole in the firewall, it's coming from the cowl area and you can differentiate it from other brand fresh air hoods.
I think that's why that moniker is heard the most. Interesting discussion though seeing different points of view on it. I say call it what ever makes the most sense to you. No matter how you refer to it, a real car guy will know what you're talking about, shucks even most non car guys know.

Learn what? When it comes to car specs I strongly doubt there is anyone that can give you a run for the money.

You want to be factual or do you want to allow "urban lore?" That green 1967 RS Camaro (with the wrong tires and NA rear spoiler) is a Z/28 even though no emblems say it is. The stripes say it is. And if equipped, it has the Air Plenum option.

If I showed you a photo of a 1969 Camaro Pace Car, I would say it had the Ducted Hood/Super Scoop. And a photo of a 1970 Chevelle SS with stripes, hood pins and the rotating hood "door" would be equipped with the Cowl Induction option - it says so right on the hood bulge, sales brochure and marketing ads.

If people want to say the 1967/1968/1969 Z/28 had Cowl Induction, are they describing the operation or are they attaching an incorrect moniker? Just like when they say a car is "radio delete." The correct moniker is: "no radio ordered."
