4.600 x 4.250 = 565
4.600 x 4.300 = 572
4.560 x 4.300 = 562
4.600 x 4.300 = 572
4.560 x 4.300 = 562
OK next question. How far can a A460 block be bored?4.600 x 4.250 = 565
4.600 x 4.300 = 572
4.560 x 4.300 = 562
It could be worn out if it was a 4.560" bore, not sure I understand your question? What's the piston to wall clearance?So its possible that this could be worn out??
