    I think they use the same as a KB 6. Maybe someone else will answer. Robert ? I have some that could be bored to 4.310.

    It might be a good idea to accurately measure the block bore top and bottom and the register depth to verify that the original sleeve design will work. It is remotely possible that the block has been modified or rebored from the original sizes. Just my .02
