When only brute force will do, a Chevrolet big block is still the ultimate choice. Built for torque, durability and sheer presence, these engines embody the golden era of American performance.

Legendary Displacement

Our big block range covers 454, 502, 572 and even 632 cubic-inch options. With power levels exceeding 600 horsepower and torque to match, they deliver relentless acceleration whether you’re building a drag car, race boat or custom muscle project.

Modern Engineering, Classic Character

Today’s big blocks feature improved aluminium heads, roller valvetrains and modern sealing, offering old-school muscle with contemporary reliability.

Built and Tested for Performance

Every big block crate engine supplied by Billy’s Speed Shop is dyno-proven and supported by manufacturer warranty. Choose from long blocks or turn-key packages complete with ignition, carburettor or EFI systems.

Raw, unmistakable, and unmatched, nothing commands attention quite like a big block.
