CLASSIC SMALL-BLOCK STROKER WITH MODERN EFI

It’s hard to beat the classic 383 “stroker” for Small-Block torque, but Chevrolet Performance engineers found a way by matching it with the driving convenience of electronic fuel injection. The SP383 EFI also features a high-performance roller camshaft and lightweight aluminum, and Fast Burn-style cylinder heads with modern valvetrain technology that includes beehive-type valve springs.
