Original OEM Application Reference

The completed application table identifies the original donor configuration. Replacement compatibility depends on the engine code, year, controls, sensors, accessories, mounting and drivetrain arrangement. A conversion into another vehicle requires its own parts and integration plan.

Factory power figures, when entered above, are historical ratings for the identified donor configuration. They do not represent measured output of this used engine. Review the individual condition, modifications and any documented testing.

V6 Platform Overview This six-cylinder engine package provides a starting point for a replacement-engine project built around the verified donor configuration. Review the engine size, factory specifications, controls and recorded components to choose a package suited to your vehicle and intended use. Benefits and operating characteristics depend on the particular V6 engine family and its condition.

For a classic-car conversion, a V6 can be considered where its verified dimensions, output and drivetrain arrangement suit the build. Matching the mounts, fuel system, cooling, exhaust, throttle hardware and supplied transmission is essential. For an electronically managed engine, match the controller, sensors, wiring and calibration to the actual donor. Contact Hawks Motorsports for available supporting parts and package details.

Confirm the actual engine identity and donor configuration before ordering installation parts. Verify mounts, bellhousing and transmission compatibility, oil-pan and hood clearance, accessory alignment, exhaust routing, cooling connections and fuel-delivery requirements. Match cable or electronic throttle hardware to the configuration. Where electronic controls apply, verify the controller, harness, sensors, ignition and calibration together; do not assume every V6 shares the same electronics.

Confirm the supplied transmission designation, identification, drive configuration, shifter, clutch or converter, output connection, mounts and control requirements against the package contents. Record any modifications and follow the appropriate donor-specific installation and service information.

Which V6 and transmission are supplied?

Review the recorded donor year, model, VIN, engine code and displacement for this stock number. The supplied transmission is identified by its designation and tag. The individual photographs and This Product Includes identify the confirmed package contents.

Will this package fit my vehicle?

Compatibility requires comparison of the actual engine code, donor year, drive configuration, mounts, controls, accessories and transmission requirements. Similar displacement or appearance alone does not establish interchange. Contact Hawks with your vehicle details and stock number.

Can I order a compatible new wiring harness?

For applications requiring engine wiring, ask sales about a new standalone harness matched to the actual engine, controller and supplied transmission. The original GM harness is excluded under the package policy. Additional charges apply and availability must be confirmed.

What should I review before a replacement or conversion?

Review donor mileage, condition, running video, documented tests, modifications, warranty terms and supplied components. Confirm fuel delivery, throttle hardware, cooling, exhaust clearance and the drivetrain arrangement for your installation. Factory ratings are reference figures rather than a measurement of this used engine.
