Cylinder bore wall chipped

I have a 400 small block that was seized. While I was attemping to get the piston out, I chipped the bottom end of the bore wall.

The piston still have enought room to lower in the bore with out exposing the chipped portion. Can I still use the block?

yep just roll the sharp edge off the chip .long as the skrit of the pistons is still some what covered by the lowest part of the bore your ok

okay thanks... jus wanted to make there will be no pressure problems
