My 1360 Hypatecs look like that too, but remember the piston diameter there is a lot less than at the skirt, so when fitted there is a (little) bit of clearance. :D

+.030" pistons are not a common size for Minis nowadays. It is/was popular with racers because it's just within the 1300cc capacity limit.

So your engine builder is a twat.


I generally don't argue with professional even when I know I'm right. They are old, and forgetful you gotta give them a break!

And Isn't 40thou 1312cc? If we bother to be more accurate with 1299cc, 1275cc, 1293cc, shouldn't we atleast give 1310cc it's correct number, to 4 significant figures?
