340 Piston identification. Silvolite?
pretty sure based in searching threads they are Silvolite, the only markings is the 60 over and a B296 on the inside. I came across an insane mostly Mopar parts hoard, one of the 340’s I picked up had been machined, crank turned (to not sure what) and 1.88 j heads rebuilt but I don’t think they were planned, it came with these pistons, does anyone know what these are and what compression ratio they are. Would they be good in a j head motor? What’s the ideal compression ratio trying to build a pretty hot but streetable 340
