I have a set of STD 428 pistons, all usable, all came out of a rebuilt 428 I bought to build a 462.
The issue is, they do not seem to be a matched set. However, send me a PM if someone needs them, there is some value
I have:
5 Ford "Super" pistons 4.13 bore, used, but measure good, I measured both ring lands and skirts, should be an original Ford cast SCJ piston
2 L2287P pistons, pretty sure forged, 4.13 bore, very nice shape, measure good, almost look new, standard as well, but seem to have about 1-2cc more dish than the Supers
1 No part number matching piston to the L2287P, also very nice shape, seems to match the 2287P in dish and shape
All pistons are 428 pin height, standard bore (4.13) with good pins and c-clips and are clean. I would not hesitate running any or all of these, but they clearly aren't a matched set. If you need them, let me know, I'll go easy on price
