LT5 Platform Overview The C4 ZR-1 LT5 combines a 5.7L V8 with aluminum construction, dual overhead camshafts, four valves per cylinder and electronically managed port fuel injection. Its distinctive architecture makes it a specialized choice for a ZR-1 restoration or a carefully planned performance project.
For a classic-car conversion, the LT5 offers a distinctive DOHC V8 alternative. The installation must account for the engine’s dimensions, hood and exhaust clearance, mounts, fuel delivery, cooling, intake controls and the intended transmission. Match the wiring and calibration to the actual engine; this package’s cut harness requires repair. Contact Hawks Motorsports for package details and available supporting parts.

Have the cut engine harness inspected and repaired for the actual engine and control configuration before installation or operation. Verify connector condition, circuit continuity, insulation and routing. Match the engine controller/calibration, injectors, fuel supply and return, throttle linkage and applicable intake/secondary-port controls to the LT5 version.
Confirm engine mounts, oil-pan and hood clearance, cooling, accessories, manifolds, exhaust connections and the buyer’s intended transmission. The supplied manifolds and catalytic converters require vehicle-specific compatibility checks. Installation notes do not establish that unlisted components are included or that testing has been performed.
