One gram is darn close for your application. You will notice a
difference when ya fire up the new beast.

The machine shop found the biggest discrepancy in couple of rod big
ends - 10g?.

Was this engine a first time run motor and never been into before?...

I got this engine in pieces with 1500 loged hours and rebuilt it. I
put about 85hrs on it since then. But the vib got annoying above
2400rpm. Here in SD its not ideal flying weather till Feb. so I decided
to use the time to improve the engine.
