Given that the first Z/28 was a vin code for a performance package to compete in the Trans Am racing with a limit on HP, my request would be this:
1. Eaton four rotor SC DI V-6 with 415 Hp.
2. Pedders Coil over suspension Lowered 1.5 inches.
3. Low restriction Cats and exhaust.
4. Z/28 spoiler similar to the dovetail.
5.Z/28 unique front fascia
6. Custom colors like Dupont hot hues or house of kolors.
7. Z/28 badging on outside and interior.
8. Z/28 special wheels.
This car would be priced somewhere between a fully loaded 2LT and 2SS.
Anything with more HP and equipment than a 2SS let's just call it a ZL1.
