I got a used 78 3.8 turbo motor for next to nothing. I pulled the oil pan off while installing some new gaskets. Looks like stock 3 dot rods but I don't think the pistons look stock. Supposedly the motor was rebuilt in the late 80s. Looks like the pistons say bohnalite se-6241. Never heard of them. Couldn't find any info online. They don't look forged to me. IDK if they are just cast or hypereutectic or what. Any one know anything about these?
