GM LS
Compact, lightweight, durable, and highly upgradeable, the GM LS Gen III/IV small-block produces robust power with simple modifications. Launched in 1997 in the C5 Chevrolet Corvette, it replaced the classic SBC Gen I/II platform and established itself as the modern standard for engine swaps. Despite ending factory production, the LS remains a leading performance V8. Its deep-skirt block and straightforward single-cam design deliver exceptional durability, supporting aggressive tuning and forced induction. Boasting compact packaging, versatile fitment for classic muscle cars and trucks, and strong upgrade potential, it remains the premier platform for restomod, swap, and drag racing builds.
