I purchased the 5.3L V8 LS Engine + 2WD Automatic Transmission from Power Drive Engines, and the results exceeded my expectations. The engine runs strong with smooth idle, and the transmission shifts flawlessly. Installation went smoothly, and everything arrived clean and well-prepped. Power Drive Engines clearly knows how to deliver quality drivetrain packages.
