A strong platform was needed for Ray Lichtenberg's 03 Suburban, so a GM LSX block was choosen. A Magnussen supercharger was to be added, but was still in the development stage at the finish of this engine build. This engine was impressive naturally aspirated even with only 10 to 1 compression. 587hp & 531lbs/ft. Internals include Callies crank, CompStar rods, Manley pistons, Lingenfelter GT-19 cam, and ported L92 heads by West Coast Cylinder Heads. With the supercharger on, a recent trip to the dragstrip netted a very impressive 12.83 in this monster of a vehicle.
