I didn't really check for any before I put the engine together :(

Is the oil pan still off or have you installed the engine already? The only way to find out is look at the underside of the piston for a part number . Maybe a Ford guy can recognize them.

Doubt if Ford guy can tell. It's a small block chevy. Pistons look like cast replacement from here. As mentioned, check for brand/no. on inside of skirt.

They dont look like cast rebuilder pistons to me. They have a knotch on the one side and the ring looking thing in the middle. Is this an old build they look like old style after market pistons.

With the marks and the thing in the center of the piston. I would not run them unless they were my last choice. They look like they will cause hot spots and preignition. Are they drilled for expansion. Might be for extreame heat.

But without the exact part number there is no way to tell if they are good or bad. So anything answer will be a WAG on my part.

Pistons w/the machine tooling locating divot like that aren't seem much any more, but they used to be common. Mainly on pistons like Badger and Silvolite. Good chance they're cast non hypereutectic.
