When my first 409, turned a bearing in the 70's, I got fed up, and I pulled it out and laid it upside down, with the lifter gallery, facing the floor. Dumped some oil on the crank and rods. I then, threw a kid's plastic swimming pool over it and forgot about it When I decided I wanted to use it again, in the 90's, it was so stuck, I had to drill holes, in the piston's, to get them out.With the swimming pool over it, the mice had a commune in there.
