They seemed to do quite well with a Rover V8.
Definitely - a quick car in its day. The last Plus8 used the BMW 4.4 litre V8 which must be properly accelerative, even by today's standards. They've just done a final run of 50 (stupidly expensive and all sold) as apparently BMW have ceased production of the engine. The 'everyday' Morgan now uses the 3.6 litre V6 from the Ford Mustang.
