Let a competent machinist determine if you need to bore the block, maybe a hone will do the trick. Try to match weights with the new/old stuff to avoid major balancing on the crank later. Look for " off the shelf " parts rather than custom. Consider a matched bal. crank, rod, piston kit with bearings and rings. Could save you in the long run. Fatigue is hard to measure.
