Hi R,
The rumour has always been the liners moves. But that's not true.
The problem is, when you liner a block. It makes the walls thinner on the bottom half of the water manifold side. This is were the block is shaped around the bore.
There is NO problem with a standard engine.
But when tuning, and putting more force through the block. They can break around the base.
But good blocks are now very scarce, and even the best engine builders are useing linered blocks for tuned engines.
But they bolt everything over the head to reduce the upward forces above the 8 block studs.
Tony.
