Build Maximum Power with Factory-Engineered Parts
Chevrolet Performance has engineered and built Big-Blocks longer than anyone, so you can trust our parts to deliver the power and durability you demand – whether you’re on the street, strip or trailering your vintage Chevy over the Rocky Mountains!
Our lineup of Big-Block parts starts with brand-new GM cylinder blocks that are stronger than previous production designs, combining design elements of the Mark IV and Gen V blocks.
That means they’ll stand up better to the high horsepower and monster torque levels a big-block is capable of generating. We’ve
even got an updated version of the legendary aluminum ZL-1 block that’s perfect for resto-mod projects and COPO tribute cars.
When it comes to the best-performing rotating parts and cylinder heads, including rectangular-port and oval-port and lightweight aluminum versions of the heads, nobody has the Big-Block covered like Chevrolet Performance. Don’t settle for used, reconditioned or “seasoned” parts. Our parts are competitively priced and often deliver greater strength and performance than used production components.
When it comes to Big-Block power and durability, trust the factory. Trust Chevrolet Performance.
