Also accompanied by a change of rev counter with a different red line - 6500 rpm on the 3.65:1 early cars and 6000 rpm thereafter on the 3.44:1.

The change from 3.65 to 3.44 occurred around May/June 1971 at the same time (give or take a week or two) as dry replaced Hydro.

The 6500 to 6000 rev counter change meant that the GT could use the Marina 1800 TC rev counter. 1.8 Supers were 5500 iirc.

Here’s a good question for you GT Guru’s ( at least I think it is)
The early GTs were rated at 59 BHP then from 74 to 80 they were 54BHP how did they loose that 5 brake?

Cheers for now Gray.

Early GTs used an AEG 538 cam, later ones used an AEG 523. Also there was a change in distributor type.
