400 Sonic Test Results

The difference in the .020 and .032 overbore is .006 per side. If you can’t get .006 more out of an overbore, you are going too big to begin with.

IOW’s, if it will go .020 and be safe, an .032 overbore is fine.

You know, I completely spaced and didn’t think about splitting the .03 overbore in half to reflect the actual amount removed. I feel a lot better about the 0.32 overbore. Thanks

what would be a definite “too thin” measurement? Anything less than .100?
