Rover V8 Engine - 4.5

4.5

Not to be confused with the later 4.6 litre engine which TVR badged as a '4.5' for the Chimaera, there also existed a version with an 80 mm (3.1 in) crank and 94 mm (3.7 in) bore giving 4,444 cc (271.2 cu in) capacity, which was used by TVR in the low-volume special 450 SEAC, the race version thereof and the subsequent Tuscan Challenge racers. A tiny number of Griffith and Chimaera road cars were built with a version of this engine, known as the '450 BV' (Big Valve).
