Chevrolet Performance ZZ572 Base Long Block Crate Engines 19331581

The ZZ572 Base displaces 572 cubic inches, built around a cast-iron block with aluminum cylinder heads, a forged-steel crankshaft, and a hydraulic roller camshaft. Compression sits at 9.6:1 with internal engine balance, and Chevrolet Performance notes the combination can support well over 600 hp once a buyer adds the induction, ignition, and tuning to match their build.

Why this is a "base" long block

Nothing beyond the long block ships on this unit: no carburetor, no throttle body, no distributor, and no water pump, which keeps it open to carbureted or EFI plans and to turbocharger or supercharger projects without paying for induction hardware you would likely replace anyway. The oil pan, valve covers, timing cover, and harmonic balancer are installed, along with spark plugs.

Before you commit to a combination

Because so much is left to the builder, line up your intake, ignition, and water pump sourcing before the engine arrives, and budget for professional installation and tuning given the scale of this big-block. Chevrolet Performance recommends a minimum of 91 octane fuel for pump-gas street use.

Q: Does this come with a carburetor or fuel injection already set up? No, this is a bare long block; you add the induction system that fits your plans.

Q: Is it suitable for forced induction? The cast-iron block and forged internals are built to handle that kind of project, but plan your own supporting components.
