I'm trying to help a widow id and value some 1st gen hemi stuff. I think it is all 354 stuff. I have some casting numbers so any help would be helpful. I have a long block with the casting numbers of 1619629-2 and head numbers of 1619823-2. I have an extra block with the same 1619629-2 and another block with casting numbers of 1327429-1. There are also two extra heads with numbers 1731528. The are some misc rockers and stuff and may be some more parts. I was hoping to find some 426 stuff but he had sold it years before. Is there a website or group that deals in these motors specifically? Thanks for the help.
