Anyone help ID this piston?

We were given this piston. It was shipped to the past owner many moons ago. It was in a (Bell auta parts) box. He said Bell sold performance parts years ago. Bell California to be exact.

He does not remember what he ordered it for. It has a part number stamped inside the piston JE 130 They are into Fords so my guess would be something along those lines. It is 3 15/16 in diameter.

Chev small block 4"
Mopar small block 4"

BUT the answer is Ford flathead .
