I have a set of 312 (ECZ) rods that I took from an engine that I bought for the crank.  I have no idea what they are worth, so if anybody needs a set, make an offer.  Two of the rods had been replaced at some time or other because there are two "7" and two "8" rods.  I'm pretty sure they need to  be re-bushed so take that in consideration.  The engine also had a set of .030 over pistons that look to be ok.
