MP 557/296 small block cam, advance or straight up

Thanks for the replies, I think it will end up advanced if there is room to run it that way. The 273 rockers would be nice to replace but going to run them cause that is what I have for now. I did change out the adjusters that have lock nuts on them to keep them from loosening up. They have seen 7k with the old cam more than a few times.
