Now you all have me really curious as to bore clearances, will a bore that is .0004 or .0007 really cause an engine any real hp problems or sealing and wear problems.
Maybe not, but his was more than twice that extra...which is more critical on very small bores like he is dealing with.

Lol, did you add another zero again? Just remember, in fractional decimal representation, there's one less zero! 1 thousand = 1000 -> 3 zeros. 1 thousandth = 0.001 -> 2 zeros.

:wink:

Or I suppose you could say one of the three zeros lives on left side of the decimal... :-k
