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.

my buddy gave me a great deal on a set of Molner rods and it has a set of 4.060 ractec forged pistons on them that are set up for a 3.79" stroke and I thought if I could use them it would make a killer small block.

I know, I am kind of working backwards... story of my life
