Built With Quality Components

This isn’t just a bare engine block. The short block has already received important machine work and quality internal components, giving you a solid starting point for your next 454 big block Chevy build.

The fresh .030″ bore gives you a clean foundation for assembly, while the 4-bolt main block provides the type of bottom-end foundation many performance builders look for.

The factory GM steel crankshaft is paired with factory dimple rods that have been polished and fitted with 7/16″ rod bolts. Inside the cylinders are Speed-Pro hypereutectic pistons, with King rod and main bearings supporting the rotating assembly.

New Dura-Bond cam bearings have also been installed.

Why Buy This 454 Short Block?

Building a high-performance big block from scratch can quickly become expensive once you add up the cost of a block, machine work, crankshaft, rods, pistons, bearings, and other internal components.

This setup gives you a head start.

Instead of starting with a completely bare block, you’re getting a fresh 454 short block foundation with many of the major bottom-end components already in place.

It’s an excellent option for someone building a:

• Classic Chevy muscle car
• Street performance car
• Drag racing project
• Pro Street build
• Big-block swap
• Custom hot rod
• High-performance truck
• Weekend race car
• Restoration project

Finish It Your Way

One of the biggest advantages of buying a short block like this is that you can choose the top-end combination that matches your goals.

Heads and camshaft are NOT included, allowing you to select the combination you want rather than paying for parts you don’t need.

Whether you’re putting together a traditional naturally aspirated 454 or planning a more serious performance combination, this short block gives you a strong starting point.
