This is a street motor going in my 2000 Durango. Bores are good no need for overbore. OEM pistons only have 35k on them not afraid to reuse. This engine will never see NOS or north of 5500 rpm.

All other things being equal, would you have the block squared and decked to bring factory pistons to even w deck, or would you buy KB107 and have the rotating assy rebalanced?

Thanks in advance.
