With over 45 years of engineering and motor racing experience with Aston Martins, the name Richard Stewart Williams is synonymous with performance – performance that has been demonstrated from club and historic racing through to the Aston Martin factory World Sports Car Championship effort including the Le Mans 24 hours.
Using this unique development experience, we are proud to offer our customers the 7.0 Litre Aston Martin Engine
Our 7.0 Litre engine conversion is offered in 3 different configurations.
- Automatic specification which concentrates on mid range torque to suit the automatic gearchange characteristics. Punchy 440 bhp and a hefty and desirably flat torque curve peaking at 520 lb ft
- Manual specification based on a 580x Vantage offering a blistering 510 bhp and 530 lb ft torque
- Fuel injected specification for the ultimate in both performance and refinement.
When your engine is converted in our workshop everything is carried out in-house, from the removal of the engine through to the machining, balancing, reassembly and testing. Now is the ideal time to carry-out engine bay cosmetic enhancements.
After assembly the engine is installed on our dynamometer, run in and power-run to optimise carburetion, ignition timing and other variables. Customers are welcome to view any of the work being carried out but we strongly recommend they don’t miss out on seeing their engine undergoing dynamometer testing.
The package includes upgrades to engine mountings, differential mountings and differential carrier.

We also offer the optimum braking packages for your car to provide the ultimate in stopping power within the constraints of the car’s original wheels and appearance.
After fitting the engine to your car we carry out an extensive road test prior to handover.
