340 Is done for

Well the machine shop has advised me while it is rebuildable its not worth it.

Look at a .40" over bore, the caps have been bounceing off the block... also needs a serious line bore as there are some huge variations in size of the caps.

The crank is already .10' under and needs to be cut but has cracks in the radius of #2 and #4 and they cant say for sure that the cut will clean them up... and the crank would be "soft" after that anyways.

In short I need to source a good 340 short block or I want a virgin 360.
