Bring extreme power and modern big-block performance to your next scale build with the Chevrolet 632ci Crate Big Block Engine & Transmission by MCS Design. Modeled after the newly released GM Performance 1000+ horsepower ZZ632 crate motor, this ultra-detailed resin engine is perfect for drag racing builds, tubbed street machines, pro-touring cars, and high-end show projects.
Designed completely from scratch, this kit captures the aggressive proportions and modern hardware of the real 632—bowtie alloy heads, 632-specific valve covers, raised single-plane intake, a Wilson 4-barrel throttle body, and a removable coil tray located underneath the intake for clean detailing and wiring.
This updated version adds a full billet pulley system, integrated belt drive, two-piece air cover, and an optional second fuel rail setup. Big-diameter equal-length headers, ignition wire holes, and fastener/bolt details make this one of the most complete and accurate 632 kits available.

Tremec TR6060 Automatic
Tremec TKO600 Manual
