A couple of days ago I picked up a batch of Mk 1 and Mk 2 Cooper S blocks with matching caps to add to the collection. They all have surface very minor rust & years of dust on the bores. What size are they?

70.58mm
71.55mm
71.55mm
70.55mm
71.36mm

many thanks

74 is on the limit, but at 72 you have 72.5, 73.0, and 73.5 left. Without offset boring.
The 72.5mm are Graham Russell's pistons.

GR told me he can sleeve them back to standard - can that be done when they're at 74?

Need to ask him, I know he can do this from 73.5mm.
Waste of money unless it's an S block, IMO.
