1100+HP 632ci Big Block Chevy

At Prestige Motorsports, we were inspired to take on the challenge of outpacing Chevrolet Performance’s ZZ632 crate engine—a 1,000-horsepower powerhouse that turned heads upon its release. While the ZZ632 is impressive, its limited availability and locked ECU present challenges for tuners, voiding the warranty if modifications are made. In collaboration with Holley, we developed an engine package that not only rivals the ZZ632 but surpasses it by 100 horsepower. Built using readily available off-the-shelf components, our engine is both powerful and tunable without the restrictions of the factory system. Jeff Huneycutt of The Horsepower Monster was there to document the build and testing, showcasing the exceptional performance of this remarkable engine. Article on build
