Product Details

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. They matched it with the driving convenience of electronic fuel injection!
Rated at 450 horsepower and 436 lb.-ft. of torque, the SP383 EFI also features a high-performance roller camshaft and lightweight aluminum, Fast Burn-style cylinder heads with modern valvetrain technology that includes beehive-type valve springs and aluminum roller rocker arms.
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.
Our SP383 EFI Deluxe kit includes the distributor, damper and flexplate, ready to install. The SP383 EFI Turn-Key kit is also available (P/N 19419199).
