SP383 Chevrolet SEMA 2019

Chevrolet Performance will be taking the time to celebrate the history of the small block V8 during the 2019 SEMA Show. For 65 years the small block Chevrolet Performance crate engines have found their way into the engine bays of everything from pickup trucks and muscle cars, on up to motorhomes, import vehicles, race cars, and various watercraft. In order to properly mark this anniversary, Chevrolet has just unveiled its all new all-new SP383 EFI crate motor on the eve of the 2019 SEMA Show.

The new SP383 EFI aims to mesh the fan favorite big torque capability delivered by a long-stroke 383 cubic-inch (6.2L) motor with the modern convenience and drivability of electronic fuel injection. The new SP383 EFI is largely based on the Chevrolet Performance ZZ6 EFI crate engine, utilizing the same high-flow cylinder heads with modern valve train technology. The new 383 features a longer, 3.800-inch stroke which helps the motor to produce more torque than the ZZ6 EFI crate.

Other engine features include a port-style injection system, with injectors plumbed in the carburetor-style intake manifold. In order to maintain the vintage appearance of the engine for use in classic vehicles, the throttle body is now mounted where a carburetor is traditionally found. Chevrolet states that the SP383 EFI is rated at 450 horsepower and 436 lb-ft of torque, not far off from either the LT1 V8 found in the sixth-generation Camaro or the LT2 found in the new mid-engine Corvette.

Two versions of the engine will be available through Chevrolet Performance: the SP383 EFI Deluxe and the SP383 EFI Turn Key. The Deluxe kit is the more basic of the two, and it includes the throttle body, a distributor, as well as the damper and flexplate. Opt for the pricier Turn Key variant, and the kit comes with the Deluxe parts, but adds an air cleaner, the front-end accessory drive, a breather, and the PCV valve and starter. Chevrolet states that both crate engine kits include a “plug and play” engine controller and harness.

The small block Chevy V8 has been a part of American car culture since 1955, and we love that Chevrolet is still dedicated to producing these motors for car enthusiasts. The SP383 EFI will join a lineup of over 50 crate engines currently offered by Chevrolet Performance, which is something special in this age of fossil-fuel uncertainty.
