About the LY6 6L90 Liftout Swap

The LY6 is GM’s iron-block 6.0L V8 from 2007-and-later heavy-duty trucks. It uses rectangle-port heads like the LS3 and variable valve timing, producing strong power and torque for towing. The 6L90 is the heavy-duty version of GM’s six-speed automatic, built for high torque and heavy loads. Together the LY6 6L90 liftout swap is one of the best heavy-duty LS drivetrains available.

The iron block and rectangle-port heads also make the LY6 a favourite for turbocharged builds.
