Thanks. Do you know anything about the Titan 4.9? I would imagine that they would make the walls thicker.

There's no way to make the cylinder walls thicker. Boring the block=thinner cylinder walls.

Then the cylinders would be even smaller in diameter.

The only way to build a large displacement stroker is to make the cylinders LARGER in diameter. That means removing material, not adding to it.

you are correct but i was talking sleeve to keep the block strong . Then bore the sleeve to the max . thats what they do in large small block chevys and ford strokers.
