one thing good about this issue is the thin cylinder shouldn't move around much, preventing any cracks. maybe I could add a power adder and put the boost right to it. with the aluminum caps I would think it should be a solid piece.
JMO... but the filler shrinks a bit so dont think you
wont crack a cyl.. I did it twice on the same cyl on
the same block.. but it wasnt a tall fill.. so I dont
think it was up where you need to help stiffen the cyl
walls
EDIT
Thats why some dont see any change in the bore
because it shrinks back a bit and doesnt PUSH
on the walls
