I recently read two seperate threads about guys having machine work done on engine blocks and in both cases, after a good deal of cash changed hands defects in the blocks were found that made thier use in a high performance application, impossiable, in one the cylinder walls were really way to thin even thought the block appeared to be in great shape, in the other there were micro cracks in the main webs.....heres the sad part, in both cases the shops said the owners took the parts, and stated they would re-coupe much of their machine work cost by dumping the blocks on EBAY or craigs list.
On a differant thread a crank was machined for a differant damper retention thread size,because the orriginal threads stripped out. The machinest broke off a drill bit tip deep into the crank snout, durring the repair, same deal.....on its way to resale to un-suspecting buyers.
The point here, is that this crap goes on all the time, ebay has become a dumping place for crap that would be generally un-saleable elseware or locally so Don,t assume things are as described.
