Chevrolet 383ci Stroker V8 Engine
The Chevrolet 383ci Stroker is arguably the most popular “performance” small-block Chevy (SBC) in existence. It isn’t an engine Chevy ever built on a factory assembly line; rather, it’s a “cocktail” made by taking a 350ci block and installing a 400ci crankshaft.
In 2026, the 383 remains the “Goldilocks” engine—offering significantly more torque than a 350 without the weight and size of a Big Block.

The Chevrolet 383ci Stroker V8 is one of the most respected and widely built performance versions of the legendary Chevrolet small-block platform.
Unlike factory-produced Chevrolet engines, the 383 Stroker is a custom high-performance combination created by:
- Using a Chevrolet 350 small-block block
- Installing a longer-stroke 400 small-block crankshaft
The result is:
- Increased displacement
- Stronger low-end torque
- Improved throttle response
- Excellent street and racing versatility
In 2026, the 383 remains the “Goldilocks” small-block Chevy setup:
- More torque than a traditional 350
- Lighter and more compact than a big-block V8
- Excellent aftermarket support and tuning potential
