SPS is a Chevrolet Performance Authorized Reseller!

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. 

The SP383 EFI incorporates a port-style injection system, with the injectors plumbed in a carburetor-style intake manifold and the throttle body mounted in the conventional position of the carburetor, which allows for a traditional air cleaner and a classic appearance. It’s a vintage look that offers contemporary drivability and strong performance. The SP383 EFI Deluxe kit includes the distributor, damper, and flexplate, ready to install. (Does Not Include Water Pump)
