There are still tens of thousands who buy cars that don't know a new Camaro even exists.
It is the best kept secret in the entire lower case gm lineup.
BUT, in fairness there are a great number of foreign owned companies who sell cars in the USA that I am oblivious to as well. If there isn't a moniker on them I have zero idea what they are because the majority of them don't command a second glance. I don't think the Camaro is a bad looking car, it's just that the lower level Camaro is basically an also ran in appearance. Lower case gm could have easily given the car some nicer exterior trim. Their sales tactics of "Packaging" would cause me to pass on by on certain Camaro models. If I want a car with rally stripes on the hood vs an all black hood I should be able to order the damned thing that way.

The L8T 6.6L, which is based off the the other LT1/L86/L87/L83/L84 Gen V V8's, is basically a stroked LT1/L86/L87. You add stroke and RPM... you are going the wrong direction for robust high-RPM engine. It can be done, but costs a lot more time and money to carry out.

-Increased relative piston speed.
-Increased frictional losses between the cylinder wall and rings and piston skirts.
-Increased relative stresses on the rods and crank.

You're better off, for where Camaro is currently, taking the LT2 and just adding RPM - new camshafts, modified heads and new valvetrain.

A DOHC, VCT, large-bore, short- or medium-stroke V8 is, really, the way to go for something like a next-gen Z/28 though.

A FPC adds in additional investigation towards the NVH put into the vehicle in respect to driver/passenger experience and also the vibrations into the powertrain/drivetrain attachments (engine mounts, front cradle, exhaust, exhaust mounts, transmission, clutch/converter, transmission mount... all down into the rear diff). All of that was a HUGE deal for Ford with the GT350 and GT350R-C.

The 6.6 has a shorter stroke than the LS7, which had a 7,000 rpm redline. At 3.86” stroke, the 6.6 would be capable of more RPM at the same piston speeds as the LS7. You could get another 300 rpm at 3.86 for the same piston speeds as the 4.0 at 7,000.

Where did you find these?

I recall a Z/28 for the 6thGen was a non-issue after the ZL1-1LE came out. Remember all the camo-spyshot-videos from the 'Ring back then? If they didn't build, or call it a Z/28 then, I don't see them doing it now.

The ZL1 1LE filled the bill for an all out track car, wouldn't have been a surprise if they had called it Z/28, and made a new Camaro called a Z/28 rather unnecessary. Just my $.02.

I totally agree that from a track car perspective, the ZLE made the Z28 a non-starter. Could be that the reason for calling it ZL1 1LE instead of Z28 is the supercharger. Z28 has tended to be an NA track car. But then again, so was ZL1 until it wasn’t.

Valid points.

The problem is that the ZL1 has pretty much all the equipment the Camaro can have and makes it heavier, they should have offered a Z28 variant with only 1 speaker, being able to delete ac, smaller screen, less sound deadening, lighter seats and recalibrating stuff to account for this.

Another reason people want the Z28 is because of how damn good the LS7 was, LT1 and LT4 are amazing, but add an hypothetical LT7 for the Gen 6 Z28 and suddenly you have an extra special model that will appreciate over time since it'll be so limited.

The existence of the GT2RS didn’t stop the GT3RS. The ZL1 1LE should have no bearing on the Z/28. My guess is they knew a Z/28 wasn’t realistic, so the ZLE was the next best thing. In all likelihood, the obesity of the C7 made a naturally aspirated, AFM, automatic friendly n/a engine a tall order. Especially one limited to the lower RPM range of a cam in block V8. That rolled down to the Z/28 not having an engine.

That is old, it has an upper case GM in the casting. Lol

The LT2 has GM as the casting mark. I have seen no motors with a lower case.

Comparing Porsche portfolio to Chevrolet portfolio is comparing apples to tree nuts. Porsche is a sports car and SUV company playing in the really high dollar range. They slice the bread ridiculously thin. There’s about a dozen models of 911. About 8 or 9 models of Panamera. Chevrolet is a family SUV/truck/sedan company that happens to offer a couple cool sports cars. We’re lucky to get 4 Corvette variants and 6 Camaro versions.

The ZL1 1LE had a slash like the Z/28. Purist didn't want the name used, so they didn't. The suggestion was there.

Following on the Mach E thing, watch the seventh gen be the E/28...
