Description -

Box Stock Motor, Stage 3

The Ultimate BSP motor. This is the motor that separates 1st Place from the rest of the pack. Motor is completely disassembled, inspected, parts replaced where needed, and reassembled with special attention to insure maximum performance. Head & Carb are specially selected & prepped using a Superflow flow bench. Motor is assembled with longer connecting rod, max stroke crank, and several other "tricks". These Stage 4 motors will produce over 1/2 hp than the typical "blueprinted" BSP motor, but are still 100% legal.
