David,
Thats going to be a machine when you sort it!
We had them out here but they were a four door Falcon, but I reckon the two door looks great.
Regarding the right
oil and temperature etc, and as you say if you do the quick positive gear change, even at partial throttle, with the right
oil it should last, and I dont see a problem with changing the dogs when they need it, as everything wears out. You mention a Cup box, that would be a four speed? - I reckon with my engine five gears would be better, as I dont really want to change rear ends between race and road!
