Worlds crustiest HEMI build

Any idea why a 1 yr old motor ended up like that (pulled and in a manure pile) so soon?
The farmers Dad wrecked the car...they saved the engine and some bumpers and sheet metal.

Over the years the 2x4 setup and the adjustable rockers were salvaged and the rest of the parts sat there rusting.

When I got it all the parts were on top of the manure pile turned top soil that remained after the Grandfather stopped milking cows in the 50's.

That block is what I used in my blown Hemi I put in my F100
