Moly is good for assembly, and depending on what the base lube is that carries the moly, it could make for a good run in lube, but Moly is a dry lubricant and washes off easily, so you want to be careful not to use too much or it will glob up in the housing and collect junk. Moly doesn't "stick" to metal, so even though it is one of the best lubricants, it doesn't work well in these engines. Now it were a wet sump with a quantity of oil to splash around, then it would be a great way to lube the engine for break in.
