I HIGHLY doubt it will be called Z07. Z07 was a performance code for the Z06. The Z06 is its own model. Z06 was a code back in 1963.
The RPO Z06 package first offered on ’63 models included a 20 percent larger diameter front antiroll bar, a vacuum brake booster, a dual master cylinder, sintered-metallic brake linings within power-assisted Al-Fin drums cooled by front air scoops and vented backing plates, larger diameter shocks and springs nearly twice as stiff as standard.
