Product details
  • Type Performance Package
  • Vendor Vengeance Racing
Description

The valvetrain opens up here. Custom billet camshaft, dual valve springs, CNC ported blower, full exhaust, and a calibration that accounts for all of it. Stage 4 is where the LT4 gets the sound people recognize and the power numbers that back it up. This is not a bolt-on build.

Estimated power gain: +150–170 rwhp. Estimated peak: ~800–820 rwhp. Calibrated with HP Tuners and VR RTD.

Fitment: 2015–2019 C7 Z06 (LT4) only.

Fuel: 93 octane pump gas.
