Yea, the piston size stays the same. They bore the block, OR, some blocks come sleeved from the Fak Toe Ree,, Then all they hafta do is get the old sleeve out & slap a fresh one in. IIRC, Detroits are that way,
The block has to be very close size to the sleeve, or there will be hot spots. The sleeve cant just slide in, it needs to be Tight,, for physical support and heat transfer.
