This is an engine rebuilding and modification guide that includes sections on history, engine specs, disassembly, cylinder block and bottom end reconditioning, cylinder heads and valvetrain reconditioning, balancing, step by step engine reassembly, torque values, and OEM part numbers for the popular Chevy LS series of engines.
