Posted: Tue Sep 15, 2015 9:20 pmAre you asking how many millimetres around the outside of the flywheel, or how many millimetres of travel before TDC?

Should have said I meant piston movement, which is what I'm after, as it's for setting the timing with a dial gauge as opposed to the 'positive stop' method prior to strobing
