Have this used set of hypereutectics for a 40 over block. Went low 11s and never had any problems with them. Was going to re use them but am going with forged pistons now. They have no cracks and are stamped usa in them. Not sure what brand they are. They come with good wrist pins. They also come with a brand new in box set of Total Seal conventional rings. 150$ obo takes it all. Lots of life left in these pistons for someone on a budget! Text or pm, 785 806 2331
