Chevy Big Block & Small Block Builds for Street or Strip
At Box Performance, Chevy engines are at the core of our craft.
We build engines the way real Chevy power should be—custom, powerful, and built to last. Our custom Chevy’s feature premium internals, aggressive cam profiles, and custom machining that deliver massive torque across the RPM range—without sacrificing reliability. Built to handle boost or stay naturally aspirated, these big-inch builds are proven performers.
We offer full Chevy engine builds and precision Chevy engine rebuilds tailored to your specs. From legendary Chevy small block engines like the 350 and 383 to hard-hitting Chevy big block engines like the 454 and 502, our builds deliver streetable torque, track-ready horsepower, and long-term reliability.
Popular Pick: Chevy 383 Stroker Engines.
If you're after big power from a small block platform, the Chevy 383 Stroker is one of the most popular choices we build. By combining a 400-style crank with a 350 block, the 383 delivers impressive torque and horsepower gains without going full big block.
Perfect for street-strip applications, hot rods, and muscle cars, our 383 Stroker builds are custom-tuned for your goals—whether you're looking for all-around performance or off-the-line punch.
Big Block Chevy Custom Builds.
If you're looking for power and durability, our custom Big Block Chevy engines deliver. Built from proven platforms and designed for performance.
Our 540 and 565 big blocks feature premium internals, aggressive cam profiles, and custom machining that deliver massive torque across the RPM range—without sacrificing reliability. Built to handle boost or stay naturally aspirated, these big-inch builds are proven performers.
Our high-performance Big Block Chevy builds use aftermarket blocks to create serious street and strip combinations. Popular low deck options include 540, 565, 562, 582, 602, and 622 cubic inch engines, delivering power with streetable reliability. For those who want even more displacement, our tall deck Big Block Chevy engines are built up to 638 cubic inches.

Common Chevy Questions:
Q: What’s the main difference between a small block and a big block Chevy engine?
A: The biggest difference is size—physically and in terms of displacement. Big blocks have larger bore spacing, bigger heads, and more overall mass. That allows them to support more cubic inches and more torque. Small blocks are lighter, more compact, and often rev higher, making them a great choice for street cars, lighter vehicles, or builds where space is tight.
Q: Which one makes more power—big block or small block?
A: Big blocks typically make more torque and higher horsepower at lower RPMs, which is great for drag racing, heavy vehicles, or low-end pull. Small blocks can still make serious power but usually require higher RPM and more aggressive tuning or boost to match a big block’s grunt. It really depends on how you want to drive it.
Q: Should I go with a small block or a big block for my build?
A: It depends on your goals. If you want something lightweight, responsive, and street-friendly, a small block is hard to beat. If you’re chasing big horsepower numbers, towing strength, or just want a nasty-sounding powerhouse with massive torque, go big block. At Box Performance, we’ll walk you through the best fit for your ride, budget, and driving style.
At Box Performance, we live and breathe Bowtie power.
