Engines & Blocks

Crate Engines & Engine Blocks — Complete American Performance Powertrains

Whether you're dropping a brand-new crate engine into a classic truck, building a race-ready stroker from bare iron, or converting a tired factory motor into something that makes real power, Billy's Speed Shop has the engine and engine block solutions your build demands. We stock an extensive range of complete crate engines spanning Chevrolet LS and LT families, traditional Small Block and Big Block Chevrolet, and Ford performance applications — alongside bare engine blocks for those who prefer to build their own combination from the ground up.

Crate Engines — The Fast Track to Real Power

A quality crate engine is one of the most transformative upgrades you can make to any American performance vehicle. Whether you're planning a ground-up restoration-to-performance build on a classic C10 or square-body truck, swapping into a hot rod, or breathing new life into a tired muscle car, the right crate engine gives you a known, dyno-tested power level from day one — with no guesswork about wear, tolerances or hidden problems.

Our crate engine range covers the full spectrum of American V8 performance. The Chevrolet LS and LT platform remains one of the most popular engine families in history for a very good reason: extraordinary power density, a massive aftermarket parts ecosystem, compact external dimensions, and a track record stretching from street sleepers to world-record drag cars. Whether you need an entry-level LS3-based unit producing healthy street power or a more aggressive LT4-derived combination capable of supporting forced induction, we have the right engine for your application and budget.

For builders with a connection to the classic iron of the muscle car era, our Small Block Chevy and Big Block Chevy crate engine range honours that heritage with modern manufacturing standards. Traditional SBC 350 and 383 stroker combinations deliver dependable torque and power that suits classic trucks, early Camaros, and Nova builds perfectly. Step up to the Big Block for those builds where cubic inches are non-negotiable — boulevard customs, heavy-duty haulers converted into performance machines, and traditional drag cars that live by the motto that there's no substitute for displacement.

Engine Blocks — Build Your Own Combination

For the engine builder who wants complete control over every specification, we stock bare engine blocks that form the foundation of a custom combination. Starting from a quality block allows you to specify your own bore size, deck height, cylinder preparation, and clearances — giving you an engine built precisely to your intended application, whether that's a tight-tolerance street engine built for long-term reliability or a purpose-built race combination where maximum power is the only priority.

Engine blocks in our range are manufactured to modern quality standards with consistent castings, properly prepared oil galleries, and the dimensional accuracy that professional engine builders rely on. Paired with the rotating assembly, cylinder head, and induction components available elsewhere in our catalogue, a bare block purchase is the starting point for a genuinely bespoke powertrain.

Engine Assembly Lubricants

Every engine build — whether a fresh crate engine installation or a custom assembly — benefits from correct assembly lubrication. Engine assembly lubricants protect critical components during the first moments of start-up, before the oil pump has had a chance to fully pressurise the lubrication system. Camshaft lobes, lifters, bearing surfaces and cylinder walls are particularly vulnerable during initial run-in, and using the right assembly lube is an inexpensive insurance policy against costly damage.

We stock assembly lubricants suited to both flat-tappet and roller camshaft applications, including high-zinc formulas that provide the anti-wear protection that modern low-zinc engine oils no longer deliver in adequate quantities for performance applications.
