Catch-22 is that if its a plated cylinder one won't find much in the way
of overbore pistons.

The problem is making full contact all the way around the sleeve. Any
place the sleeve fails to contact, or contacts lightly, will run hotter
than others. Sleeve will distort when heated unevenly. Maybe this will
be a problem, maybe not. No matter, sleeves were better for aluminum
block Chevrolet Vegas than the factory's bare aluminum cylinder because
the block was such a sorry design in the first place. Cast iron cylinder
head only made matters worse.
