I asked my dealer if i could buy my shortblock back from d/c. Im getting a new shortblock put in this week under warranty, the # 1 cyl is scored alittle bit. They thought broken wristpin but they dont know for sure since they got the ok to replace it they didnt look for the cause. Anyway what is a fair price to give for the old shortblock? It ran and idled fine it just started ticking( slight knock)not smoking or anything,@ 70000 miles. I cwould like to buy it back for a good rebuilt backup, i just dont know what its worth?
