What kind of pistons? You can break a motor in, in about half an hour.
Lastly, how would we know? Just go find out.
no one can really answer this question. too many variables (driver, weather, weight reduction, bad rebuild, tranny, etc etc etc etc etc etc etc etc).
like said above, just go out and run it. then come back and tell us how well you ran.
