JE Flathead Pistons 3 3/8 x 4" stroke

Finally thinning out leftover parts from Dad's garage. So I don't know the background on everything.

These are very slightly used JE pistons.

Measure 3.375. 1.436 compression height. So 4 inch stroke from what I can tell. Marked LC for Low Crown and they have buttons, not circlips. So I'm assuming these are a blower piston.

No idea what market value is. Shipping on your dime.
