Now this is how I see it!..I feel that SS is to Camaro as the ZR1 & Z06 (of late) have been to Corvette.
For example: If you go to the corvette build web page, and you choose the Z06 (LS7 @ 505hp)...you can't add the Z51 package (I’m using the Z06, as you can’t build the ZR1 as of today), which we all know if the handling package. If you choose the Standard V8 (LS3 @440hp) corvette, you then can add the Z51 Package.
From my understand the Z/28 package back in ’69 was the sport handling package
With a 327, The SS had the 350…am I wrong; please correct me if I am!
So if GM follows that pattern of thought, and history as I know it...I believe it will go like this.
Base Model (V8) = LS3 @400hp
Z/28 = LS3 @400+hp (Sport Tuned) + Handling Package. Maybe some reduced weight by have the basic interior package. Like the “1lt” interior package on the Corvette…better for Autocross (if you want to do that)
SS = LSA (Super Charged w/the Handling package & Maybe Luxury Interior)
Just my 2 Cents…and I’ll say no more!

Little off on the 69 Z/28.
GM had a bunch of weekend racers working for them and wanted to go SCCA Tans Am sedan racing. The rule book dictated cars had to be production sedans with a maximum engine displacement of 5.0 liters. So they took the 327 block, stuck a 283 crank in it (making a 302) with the best production (at the time) heads, intake, a huge cam and high compression pistons to build a super easy revving high RPM banshee of an engine. To keep to the rule book, they offered it to the public in 1967 as an option called "Special Performance Package" R.P.O code Z28. Every option had a code. Even stripes, head restraints, etc.
They under rated the HP at 290 but most people agree it was more of a 400HP motor but needed a steep rear end gear to stay in the power band. And you’d need to pull the valve covers to adjust the valves about once a week if you actually drove it daily. Not really street friendly.
In 1967 the Z28 didn't even have emblems but as word got out an polularity grew into 68 and 69, the Z28 became legendary and more ended up on the street than in Trans Am racing.
In 1970, GM pulled out of Tans Am Racing and the Z/28 ever since as been various street option packages not geared toward any form of sanctioned racing except for the IROC-Z in the 80's.
