I have some 4.060 pistons and rods that I want to use on a engine and debating on a 340 or 360. I would prefer to use the 340 but it seems to be difficult to find a 340 in either a standard bore or a ready to go .020 340 (4.060 bore). I could use a 360 but curious if anyone has issues with their blocks that prevented them to bore that much. I know I will need to get it sonic tested but if everyone is having issues going that big, there is no reason for me to explore that route.
Thanks in advance.
