Editing Rover V8 engine (section)

==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 {{convert|80|mm|in|2|abbr=on}} crank and {{convert|94|mm|in|abbr=on}} bore giving {{convert|4444|cc|L CID|1|abbr=on}} capacity, which was used by [[TVR]] in the low-volume special [[TVR 450 SEAC|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).
