[TR] advice needed on chains for pulling engine

[Paul Tegler]

each chain regardless should be rated for the lift. The 'multiple' is 
nothing more than balance.
If each chain were only rated at 250, and you were relying on 250 
x4....  and one breaks on you... they all will go as you just over 
loaded the remaining chains.
with one point on hoist and one on engine, several chains, or loops is 
another story.  PAYOR!
