Mystery Pistons help ID

here is what I know
4.040 bore
.984 wrist pin
1/16 1/16 3/16 rings
compression height around 1.50

I thought these where for stock stroke 360 3.58
but with that size C/H they seem they are for 4.00 stroke?

have no idea who made them only markings are F/T with a lighting bolt cast in underside
They sure have one big dome?
Any idea's?

Unless they are not Mopar , what else would have .984 pin size?
