connecting rods.

klrfish1968, your experiance with KB pistons is not an isolated one. I have heard similar stories from two other people. That's another reason why I dropped my 360 project and jumped on the 340 stroker with the forged pistons.

If you read the tech articles on the KB site, it says that because they run such a high (close to the piston top) 1st ring groove, you have to run a large ring gap. This is because of the heat expansion issue. But if the rings ever do bind, it rips the top of the piston off.
