Here are the specs as best I can tell. Wiseo doesn't put any markings on their custom pistons, so they have no way of telling what was ordered. The weights were taken from a kitchen scale, not a shipping scale. If you wanted them closer I could weigh them at the USPS.
They are custom Wiseco pistons I bought used in a short block. The original owner said he wanted to build a nitrous motor to take a 300 shot and then changed direction to go with a stroker. The machine shop which ordered the pistons advised that they were ordered custom because there was a lack of shelf pistons with that much dome at the time, and the guy wanted nearly 12:1 compression for the nitrous.
I was told the motor had a 1000 miles on it when I purchased it back in 2004. I suspect I've added about 20K miles to it in that time.
The pistons themselves I have not yet cleaned and there is some minor scuffing on the skirts. I would have reused them, but I did not know how big the dome was until 5 months after I ordered new heads & cam. And my SCR would've been upper 12's with them which is too steep for me on pump gas with my 59cc chamber and .040 gasket. The rings still have good tension but I don't know what they were gapped at, but I think it'd be silly not to re-ring them. I have the Spirolox as well, but I think you're supposed to replace those once removed as well.
