LS327 - 5.3 Liter - The 327 Rides Again!

First featured in 1962, the 327 was found in everything from fuel-injected Corvettes to the very first Camaros. It was renowned for its high-rpm performance and surprising torque from a comparatively small-displacement V-8. Today's LS327/327 crate engine delivers on the same virtues, cranking out 327 horsepower and 347 lb-ft of torque. It's a 5.3L LS power plant with the same 327-cubic inch displacement of the high-winding small blocks from the 1960s, but it is "breathed on" and updated by GMPP engineers with a hotter cam, Grafal-coated high-silicon pistons and more. In other words, it's perfect for re-powering your truck or dropping into your classic vehicle or street rod (check with your state or local regulatory agency for emissions regulations in your area).
