What is the bore size after you pull the sleeve? Can you bore the block large enpugh for a four inch piston?

Should be the same as a 301 which is 3 13/16 you pick up 1/4'' more bore.You have to cut out another .1875 or 3/16 for 4''.I know a 301 block can be bored 60 over their a different casted block.You could make your 263 into a 301 without the sleeves I think.
