V8 5.7, 6.3 & 7.0 litre conversions

To some owners of high performance motor cars, sufficient is simply not enough. And in an attempt to satisfy the constant demand for more power, Aston Martin Works and Richard Williams (RSW) have offered an aftermarket package to increase the capacity, power and torque of the 2 valve (and later 4 valve) V8 engine. Whilst such cars are not 'production models' in the strictest sense, I have included them for completeness.

V8 5.7, 6.3 & 7.0 litre conversions

The main photograph is an outstanding V8 Vantage Volante was photographed during to preparation for the 1999 Parade des Pilotes at Le Mans. The crackle finish black cylinder heads indicate a Factory original (Works Service) 6.3 litre engine conversion. In this case, the engine is tuned to provide 470bhp with 479lb/ft torque at 2,750 rpm (i.e. set up for maximum acceleration). As with many other cars on this site, the owner is a visitor to this site and has kindly provided additional information.

In the gallery is an example of a later series 2 BBS Vantage but fitted with an RSW 7.0 litre conversion based on the 580 X-pack engine. The 7.0 litre usually have the cam covers painted in a green crackle finish. Also cars sometimes have badges with a logo ‘SEV8N’. Although this car is a V580 BBS example, it currently has Ronal wheels, more typical of the X-pack V8 Vantage.

Also in the gallery is an example of a V8 Volante with an RSW 7.0 litre conversion, this time tuned to suit the automatic gearbox. The RSW engine is also available with fuel injection – an example is shown on the V8 Vantage Zagato page.  Needless to say, if you were to take advantage of any engine performance enhancement, you would be wise to consider the suspension, brake and cooling upgrades also available.

More recently, RSW have also introduced a 5.7 litre conversion for the AMV8.
