LSR/LTR Builder Blocks

The Freedom Series LSR and LTR aluminum engine blocks are cast from a proprietary 356 T6 Aluminum and feature spun ductile iron sleeves. Reinforced from top to bottom, our blocks are built for maximum performance with added features like added cross bracing in the lifter valley, maximized crankshaft saddle radius and a 40% larger footprint for the main cap contact surface to the skirt wall. 100% cast, engineered, machined, and assembled in Indiana.
