Vintage Forged True pistons 1957 1958 57 58 Hemi 392 Set (8)

Description

Vintage Forged True pistons 1957 1958 57 58 Hemi 392 set of 8 + 1
This is a set of 8 forged pistons. They are Art Sparks creation from back in the day. They are flat top, no dome with reliefs, so I would ASSUME they may be for a supercharged application, but don’t hold me to it. They measured out at 3.96 with a set of calipers, which should put them right at standard bore 392.
I listed them as used, however, they appear only to have handling marks and forge lines. You be the judge. I marked the stamp on the dome with a marker so it would show up in a photo. They are not marked with STD or an oversized, so my measurements the best I have.
I additional Piston included, appears to have pre-ignition marks on top. See last photo in listing.
Came from a group of early hemi and Donovan parts I picked up.
If you have questions or need other measurements, just let me know.
Good luck and bid to win!!
