Brush Research - GB334240AO GB Standard Duty Flex Hone for Block Cylinders, Aluminum Oxide, 3-3/4" Diameter, 240 Grit (Pack of 1)

Q: Will 3.75 hone work on a 5.3 ks. With bore of 3.78?

Note that the hones are manufactured oversize, on purpose. The 3-3/4" (3.750") hone, if you physically measured the diameter would be about 3.890". The hone would work in the 3.780" bore but the life of the hone in the 3.78" bore will be diminished because of the larger than expected use bore. The globules (abrasive balls) wear quickly on a new hone due to the tips of the balls (small surface area) wear on the bore walls. As the balls wear there is also less wall force applied to the cylinder wall so the honing action will be reduced. With that said the best choice is the 4" labeled hone. If you are only cleaning up a couple of cylinders then the 3-3/4" hone will work. If you are doing more than 4 cylinder bores then the next size (4") is the best choice.

Q: Will this work for my 84mm cylinder bore?

Yes the 83mm hone will work for your 84mm application as the hones are manufactured 0.140" oversize.
