Push the legendary LS7 platform past factory limits with this high-output 660 HP LS7 427ci V8 engine package, complete with a brand-new-in-box installation kit to streamline your swap.
Built on the ultra-lightweight 7.0L aluminum block architecture, this package retains the core DNA of the C6 Z06 track machine—utilizing forged steel crankshafts, ultralight titanium connecting rods, and CNC-ported aluminum cylinder heads with titanium intake valves—while upgrading the camshaft profile and calibration to extract a screaming 660 horsepower.
To ensure your installation goes smoothly from the garage floor to the first startup, this setup includes a completely new-in-box installation kit packed with all the essential hardware, gaskets, brackets, and accessories required to mount and plumb your new 427 powertrain correctly.
