What size ball/flex hone did you use for 3.78" bore? and where did you get it?

After doing some reading, I have determined that I need a 240 grit ball hone to clean up the cylinders. I was thinking the ball hone would be better than the stone hone because I am not using a torque plate to keep the cylinders true while honing. The balls would more evenly hone the cylinder wall than the stone hone.

The standard bore for a 5.3 is 3.78". Looking at the Brush Research website, there are 3.75" hones, and 4.25" hones. My assumption is that I do not want a hone that is smaller than the bore. However, I do not want to put a hone into the cylinder that is too large.

I think a 4" would probably be best, but I am having trouble finding one at a reasonable price. Which one did you use?

Ball hones don't "cut" the cylinder wall like a finger/blade hone does. If your only looking to deglaze and cleanup the walls (meaning not repairing damage), the ball hone will be fine.

I see Grainger and most other places with a 4" hone, which is fine. The balls are flexible, so they sorta bend in resistance fit against the cylinder wall. Don't go crazy and you shouldn't find yourself in a hole you can't dig out (pun intended)

I think Graingers public pricing was like $60.
