More stroke, more size, more cam, more power. More is better!

This stroked Small-Block is the latest triumph from Chevrolet Performance. Improved Fast Burn-style cylinder heads and a specific high-flow aluminum intake manifold combined with the extra cubic inches from the longer stroke, push horsepower and torque to 445!

The updated aluminum heads feature 2.00/1.55-inch valves, a unique combustion chamber design and LS-style beehive valve springs for greater high-rpm performance and durability. A hydraulic roller camshaft with more the 0.500-inch lift optimizes the airflow enabled by the high-flow head design.

The 4L70-E four-speed automatic overdrive transmission backs the SP383 with strength and durability. Put this combo to work in your classic cruiser and enjoy a great balance of performance and efficiency!

When it comes to factory-engineered performance and convenience, nothing beats Chevrolet Performance's industry-exclusive Connect & Cruise powertain systems.

The specially calibrated controllers for fuel-injected engines are designed for retrofit installations in older vehicles, for easier and quicker installation – and more importantly – operation without the need for third-party tuning.

We did the work to design and calibrate perfectly matched powertrain systems and covered them with a 24-month / 50,000-mile limited warranty.

Chevrolet Performance pioneered the performance crate engine, so when it comes to performance innovations that save time, money and guesswork, we once again lead the way! All you have to do is install, connect, and start cruising!
