Chevy Small-Block V-8 SP383 Deluxe - 19433035
Modern Technology Adds Range to the 383 Stroker!
Chevrolet Performance’s SP383 Deluxe uses LS-inspired valvetrain technology to expand its rpm range, matching the stroker combination’s traditional torque with more high-rpm horsepower. Lightweight aluminum cylinder heads based on the proven Fast Burn design are at the heart of the SP383’s performance capability.
They feature beehive-style valve springs to enable great high-rpm performance and durability, allowing the SP383 to rev higher and build more horsepower. The engine also features a forged steel stroker crankshaft, an aggressive hydraulic roller camshaft and a high-flow aluminum single-plane intake manifold. The Deluxe kit also includes a cast-iron water pump and steel balancer. The assembly includes a Holly 4-barrel carb, HEI distributor, ignition wires and spark plugs (not shown in product photo).
INSTALLATION NOTES
- Requires addition of fuel pump and starter (not included)
- 435 horsepower rating achieved during GM testing with the high-rise single-plane intake manifold (P/N 12496822) and a 770-cfm carburetor with vacuum secondaries (P/N 19420445)
- Chevrolet Performance dual-plane intake manifold (P/N 12366573) may be used to avoid hood clearance problems, but peak power may decrease by approximately 15–20 horsepower
- Comes with 12.750" externally balanced 153-tooth automatic transmission flexplate. Requires externally balanced flywheel for manual transmission.
- Not intended for marine applications
