America's favorite big-block crate engine is now available fully assembled. All the same great parts used in the ZZ502 kit engines, but fully assembled for easier-installation in your hot rod, street rod or sportsman racer. Available in two versions: base and deluxe. The base engine is a fully assembled long block with valve covers and valvetrain. The deluxe is a complete engine from intake manifold to pan. (Carburetor and starter included, but not installed because of crating.)
