Built for Boost. Forged for Power. 🔥 Meet the Boostmaster 396, the Gen V LT short block built for one thing — pressure. This isn’t an aluminum block, this is iron, chosen for its unmatched strength, ring seal, and cylinder integrity when the boost hits hard. We didn’t stop there. Our exclusive lightening program cuts 23 lbs from non-critical areas, keeping it strong where it counts and lighter where it doesn’t. Strength without compromise — that’s GPI engineering.
