This kit is made to suit vehicles fitted with the Rover alloy V8 engine with a manual transmission and includes the following:
- It will not suit the 4.6L BMW engine and later
- This kit will only suit Turbo pattern engines
- As the original GM flywheel and starter motor are used for the conversion. The bell housing will need to be modified to allow the starter motor nose to clear.
- The front coil springs on the Range Rover / Land Rover will need to be upgraded as the cast iron GM engines are heavier than the alloy Rover V8 engine.
The GM V8 engine kit consists of an adaptor plate that bolts to the rear of the engine. The standard Range Rover / Land Rover V8 bell housing then bolts to the rear of the adaptor plate. The transmission does not need repositioning for this conversion as the GM V8 engine has similar external dimensions as the Range Rover / Land Rover V8 engine.
Engine mounting kits are available to suit GM engines. The engine mounts have been designed to bolt to the side of the GM engine and then bolt directly to the original Range Rover V8 pre 1996/ Land Rover V8 pre 1999 engine mount rubber and chassis mount. The original chassis mounts do not require relocation.
The engine mounts have been designed to give you sufficient legal sump to differential clearance when used with a standard GM rear drop sump. See below for available engine mounts.
A standard 10.5" GM clutch kit can be used with the Range Rover / Land Rover 4-speed transmission as the clutch spline is the same (10 tooth).
A 10.5" GM clutch pressure plate and Rover 5-speed clutch plate can be used with the Range Rover / Land Rover 5-speed transmission.
A Range Rover / Land Rover clutch kit can be used but the GM flywheel will need to be re-drilled and tapped to accept it.
See below for available clutch kits.
The original GM flywheel and starter motor are used for the conversion. The bell housing will need to be modified to allow the starter motor nose to clear. If a hi-torque starter motor is used the bell housing modification can be minimized.
When fitting Chevy petrol engines the smaller 10.5" 153 tooth flywheel must be used as the larger 11.0" 168 tooth flywheel will not fit inside the original Range Rover / Land Rover bell housing.
Most Chevy petrol engines imported into Australia were originally fitted to automatic transmissions. Marks 4WD Adaptors manufacture flywheels to suit these engines.
