Why shift at 7000? Just been reading 'Shelby Cobra Gold Portfolio" with road test data from R & T, Sept 1962. The 260 engine in that first Cobra is rated at 260bhp at 5800 rpm, but I've seen the same bhp figure at 6500 in the same compilation. The interesting thing though is the maximum speeds and revs quoted:
4th...153mph at 7000rpm
3rd...112 at 7200
2nd...89 at 7200
1st... 67 at 7200
Why not shift at 7000 if the little rocket will pull those revs in top gear!
OK, admittedly this was a 'Press' car, and it's paper figures would not match its actual figures, but this is 1962, remember, and these figures are sensational! Can we not have this rev-ability and apparent mild enough temperament now?
Cheers!
