The Aston Martin V8 Vantage was annouced on 18th February , 1977. The V8 engine having proved to be an exceptionally reliablle and robust unit, it was clear that there was scope for a significant increase in the power that it could deliver. Revised camshafts, air-box, larger inlet valves and carburettors, new inlet manifolds and different plugs, claimed to provide an increase in power of 40% and 10% more torque. The same ZF manual gearbox as in the Aston Martin V8 Saloon was standard equipment. This was enough to give a top speed of about 170 mph and accelerate from 0-60 mph in 5.3 secs.
