Please I really need some help here. I have a couple nos set of main bearings and cannot figure out which car they are for. I cannot find the part # anywhere. I have been searching for months and no one seems to be able to figure it out. So someone told me to come to the experts here. So if someone can find it in their hearts. Hopefully someone has some vintage books?? I was told they were for a 348 chevy engine but just not sure.
Here are the specs. Thanks in advance.
