GMP-TH400ZZ427-4X - Pace Prepped & Primed ZZ427 480HP Dual Quad Satin Finish Engine with 4QT Oil Pan & TH400 Transmission Package

There are few engines that conjure up images of greatness like the 427 Chevy big-block. The ZZ427 big-block crate engine brings back all of the good things that you remember about the 427 with a few modern new upgrades. With an updated cast iron block, a 10.1:1 final compression ratio, and an aggressive hydraulic roller camshaft, the ZZ427 offers you outstanding performance while still living on low octane fuel.

The ZZ427 is an exciting trip back to one of the high points in the history of the Chevrolet big-block. With a rating of 480 horsepower and loads of torque, it's still one of the best crate engines for just about any big-block application.
