1992 Super Sprint Ford engine, Imperial or Metric fixings

[JB052]

As per title,

I'm tidying up a 1992 Ford engined Super Sprint and unable to find my thread pitch gauge, are the thread sizes metric or imperial or a mixture?

I think you are probably right.

So far, most fixings appear to be metric as far as the bolt spanner size are concerned, I have not measured actual thread sizes but a 11mm spanner seems to be getting a lot of use.
