I prefer "TunaBoat" . LOL. That would be the LD5, a distant cousin pushing 225HP. The engine has actually been around since 1962. With a lot of versions in between. It started as a 3.2L in '61. Sold to Jeep in '65. The bought back by GM and punched out to a 3.8L in '75. Viva the "Buick Fireball" . The "Garret" fed GNX version pushes 300HP out of the factory.
