65 dart gt RPM

Going to try some taller tyres hopefully next week (27inch) current tyres are 25.6. just to see what difference it makes. Problem is that a taller wide tyre will not fit on the car. But if the test tryes reduce the revs I will look at changing the gearing to 2.76 which should give a similar rev reduction to the larger tyre. Just wanted to make sure the high revs were to be expected with the current set up.
