I had a motor built for a friend for his 64 impala ss by a reputable machine shop.

11 years later I bought the impala with the rebuilt motor still on the engine stand (wrapped in a bag).

I pulled the pan just to make sure it looked ok to run, it looked like the day it was put together.

11 years after rebuild, put it in, runs *****en to this day. However, I think I have a head gasket that is marginal so my recommendation is to install a quality set of head gaskets.
