Unless you are really quite excellent post flop, I don't think 10x implied odds is enough. 8.5x is certainly not enough - since you would have to
a) get all/in 100% of the time you flop a set
and
b) never get out drawn (overpairs have 2 outs, not to mention he could hit a straight or flush.
c) he never flops an overset (which he will 1 in 8.5 as well!)

So, in order to call profitably at ~10x you need to make a little money on average even when you don't hit your set.
