Chevrolet ZL1 · Convertible
6.2-liter V8 with Eaton TVS2300 supercharger, direct injection, variable valve timing — the final evolution of the small-block architecture. 650 hp at 6,400, 650 lb-ft at 3,600. Blower pushes from 1,800 rpm, wall of torque at 3,500. Charge cooling via water/air system: perfect on street, track needs bigger coolers after lap 3. Same AFM lifter risk on automatics. The LT4 is the last factory-supercharged Camaro engine — production ended 2024, collector piece.
650 hp ZL1 convertible — for those who want it all
Everything from the ZL1 plus retractable hardtop. Heavier, less rigid than coupe. The supercharger sound top-down is impressive. Not a track car but the ultimate GT cruiser.
Engine Weaknesses 3
Same AFM risk as LT1 despite supercharged engine. Automatic versions affected.

Factory intercooler heats up from lap 3 — budget aftermarket coolers for track use.
