Well if nothings rubbing, and if the magnets were put back in correctly (e.g. N-S-N-S-....), then a little sloppiness won't hurt (it may make it slightly out of balance).
So I'd suggest a quick kV run, if you can do it. Use the lowest cell count pack you have (like a 2s if you have one, since there is no reason to go too high of an rpm). If the measured kV is close to the original specs, and if the no-load current draw is ~1-2A (I'd look at the specs too), then it is hard to see what is wrong.
