If you’re building an LS engine meant to dominate the strip, carve canyon roads, or simply crush the scales on any dyno, the BMP‑086515 Aluminum LS Engine Block is your ticket. Built from high-strength 357T6 aluminum alloy, it weighs a mere 135 lbs with caps and sleeves, giving you a rock-solid foundation without the ballast of a cast iron block. In short: strength where you need it, weight where you don’t.
