Every great engine build begins with the right foundation. Whether you’re assembling a boosted track motor or restoring a classic, our range of long blocks and short blocks provides the precision-built core you need. Billy’s Speed Shop supplies LS, small block and Ford configurations, each manufactured to exacting tolerances, dyno-tested and ready for you to finish your way.

What’s the Difference?

A short block includes the block, crankshaft, rods and pistons assembled and balanced, giving you a ready-to-build base for high-performance or custom applications. A long block adds fully assembled cylinder heads and valvetrain components, saving you time while ensuring factory-level precision. Both formats let you tailor the top-end setup, from induction to ignition, for your exact goals.

Built for Performance & Flexibility

Whether you’re chasing a reliable street motor or a forged race-ready foundation, our long and short blocks cover every type of project. Choose from LS-based builds for lightweight strength, classic small block Chevys for period-correct restorations, or modern Ford assemblies for Coyote conversions and retrofits.

Professionally Built, UK Supported

All engines are assembled to the highest standards, fully inspected, and backed by UK support. We can also supply compatible parts such as intake systems, ECUs, oil pans and accessory drives to complete your setup with confidence.

Reliable, adaptable, and ready for power, our long and short block engines are built to give your project a proven, performance-driven start.
