Which flexible ball hone to purchase?

[dibbons]

For a small block 340 .040 overbore piston (4.04 + .040 = 4.08") what size AND grit (moly ring set) should I look for in a ball cylinder hone? Thank you.

I used a Flex Hone in 4 to 4.5 inch. I "think" it is 400 grit but could be mistaken. Here is the results I got.

320 or 400...

Brush Research Manufacturing is the best there is. They are also expensive. You may be able to rent one from a local rental store as long as you can get the proper grit. Brush Research Cylinder Hone Tools

Yup get the "flex-hone" they work great the one you want is 4.00-4.500" if you look around you can get it for about 75$ worth every penny. I have a 320 grit I use for moly rings.
