Good deal. Done right they run forever. What I have seen is the old timers that had these motors (348-409) tended to run them too long without changing oil. My 409 block was good, but all the internals were worn, and the oil pan and inside was dirty. Some folks keep the oil canister (100% original) but I believe a spin on does a much better job of filtering the oil.
